Executive Summary The SEQL Project (Sustainable Environment for Quality of Life, www.seql.org ) is an integrated environmental improvement project in a 15-county North Carolina/South Carolina region surrounding Charlotte, NC. One aspect of this project is to explore using energy efficiency to benefit air quality. The SEQL desired to evaluate a new coating, Adsil, which previous studies have shown that, when applied to evaporators, condensers and fans of an air conditioner (A/C) unit, can bring the efficiency of that unit virtually back to that of a new unit, as well as prevent age-related efficiency loss due to the deterioration of heat transfer surfaces, saving both electrical power and early replacement costs. The ability to model expected energy savings with widespread use of Adsil in various types of locations (in relation to corrosive and fouling influences) would be beneficial and transferable to other communities nationwide. Energy savings reduce costs, limit the need for new generating capacity, and could under certain circumstances benefit air quality. However, quantifiable air quality benefits would depend on the amount of energy savings and the extent to which, and where, fossil fuel-fired power plants reduced emissions as a result of those energy savings. In order to further evaluate this opportunity, the United States Environmental Protection Agency (EPA), working with SEQL, competitively selected an engineering firm, MACTEC Engineering and Consulting, Inc. (MACTEC) to conduct a pilot program. This pilot was required to evaluate the possible energy-related benefits of coating A/C units in the SEQL area with Adsil and to provide a method to predict the energy savings from similar applications on a widespread basis elsewhere. The total tonnage of air conditioning units included in this study is approximately 2,500 tons. There were three primary objectives for this project: 1. Provide the EPA with a spreadsheet-based calculation methodology to accurately predict the degradation in energy efficiency ratio (EER) for air-cooled heating, ventilating and air conditioning (HVAC) equipment coils; 2. Document the EER improvement for air-cooled HVAC equipment cleaned and coated with Adsil cleansers and coatings; and 3. Provide a tool for estimating the energy savings for an HVAC unit cleaned and coated using this protocol. MACTEC evaluated the impact of Adsil application to 45 HVAC units in the SEQL area and to three units outside the SEQL area. The results of this evaluation show that the Adsil treatment can be expected to improve the efficiency of existing HVAC units by approximately 12% based on the ton-weighted average method used in this project. The

data was statistically evaluated and determined to be significant at the 99% confidence level. Utility bill analysis was determined to be an inappropriate measurement tool for EER changes and therefore actual efficiency measurements for each HVAC unit were performed. Three tests were used including a calculation method, a power and capacity measurement, and a refrigerantbased measurement using the Service Assistant as available from Honeywell Controls. Two baseline studies were conducted to establish the accuracy of each testing protocol and which involved repeated tests on two units. Repeatability in measurements was demonstrated in these tests and it was determined that the Service Assistant instrument provided the most repeatable and accurate measurements of HVAC EER. The generic compressor curve used for many of the SEQL area tests was found to underestimate the actual savings demonstrated in the pilot baseline study tests. The condenser test methodology was generally less accurate but showed greater increases in EER as a result of the Adsil treatment. A degradation prediction tool for HVAC units was created in this pilot program. This spreadsheet-based tool was calibrated against actual EER measurements and was found to be very accurate in predicting the EER degradation of a population of HVAC units in the SEQL area. An energy savings projection tool was also created based on the results of this study. This tool can be easily adapted by facility owners and operators to estimate their energy savings, dollar savings, and avoided pollution emissions as a result of the application of Adsil to air-cooled HVAC equipment. This tool estimates that annual dollar savings for the 150 units coated in the SEQL area will exceed $37,000 based on a blended electric rate of $0.08 per kWh.. MACTEC believes that this product demonstrated significant savings for air-cooled HVAC equipment.

1. Introduction and Project Objectives The SEQL Project (Sustainable Environment for Quality of Life) is an integrated environmental improvement project in the North Carolina/South Carolina region surrounding Charlotte, NC. This project is led by the region’s Councils of Government (COGs) —the Centralina COG on the NC side of the border and the Catawba COG on the SC side. One aspect of this project is to use energy efficiency to benefit air quality.

SEQL Region

The SEQL desired to evaluate a new coating, Adsil, which when applied to evaporators, condensers and fans of an air conditioner (A/C) unit, can bring the efficiency of that unit virtually back to that of a new unit, as well as prevent age-related efficiency loss due to the deterioration of heat transfer surfaces, saving both electrical power and early replacement costs. This coating has been well tested for this benefit in other climactic areas, including the Naval Air Station in Jacksonville, FL. The increases in unit efficiency in these tests has been well documented (this documentation is available at www.adsil.com). The ability to model expected energy savings with widespread use of Adsil in various types of locations (in relation to corrosive and fouling influences) would be beneficial and transferable to other communities nationwide.

savings reduce costs, limit the need for new generating capacity, and could be used in some areas to benefit air quality. However, quantifiable air quality benefits would depend on where and what kind of plants changed power production as a result of energy savings. In order to further evaluate this opportunity, the United States Environmental Protection Agency (EPA), working with SEQL, competitively selected an engineering firm, MACTEC Engineering and Consulting, Inc. (MACTEC) to conduct a pilot program. This pilot was required to evaluate the possible energy-related benefits of coating A/C units in the SEQL area with Adsil and to provide a method to predict the energy savings from similar applications on a widespread basis elsewhere. To develop a prediction model, additional data was required to be collected to supplement existing data. For example, to evaluate possible benefits, EPA required data to be collected on the degradation curve of A/C units related to pollution and other corrosive or fouling influences. This included data collection for units besides those being coated. This pilot, funded by the US EPA, was to include as many as 30 buildings’ units and be completed by September of 2004. The preliminary list of buildings/units is shown in Table A-1 in Appendix A for information purposes. The total tonnage of air conditioning units included in this study is approximately 2,500 tons. Project Objectives There were three primary objectives for this project: 1. Provide the EPA with a spreadsheet-based calculation methodology to accurately predict the degradation in energy efficiency ratio (EER) for air-cooled heating, ventilating and air conditioning (HVAC) equipment coils; 2. Document the EER improvement for air-cooled HVAC equipment cleaned and coated with Adsil cleansers and coatings; and 3. Provide a tool for estimating the energy savings for an HVAC unit cleaned and coated using this protocol. An overview of the tasks used to provide data to meet these objectives are provided in the next section.

2. Description of Tasks A number of tasks were completed in order to ensure accurate and credible tools were created. These tasks are described below: Task 1: Baseline Testing MACTEC selected two units in the Gainesville, Florida area as control tests. One unit is a 1991 5-ton split-system air conditioner. The other unit is a 2001 split-system heat pump. The efficiency of each of these units was measured between 10 and 20 times at various outdoor air temperatures and differing indoor wet bulb temperatures to ensure that the testing processes were repeatable and accurate. Three methods were used (see Section 3 for description) to determine the EER of these two pieces of equipment before cleaning and coating with Adsil. Multiple tests were conducted post-Adsil application and the results were compared for repeatability. These results may be seen in Appendices B and C. Task 2: Test Procedure Comparison with Traditional Data Logger Analysis In order to further support the proposed testing process, MACTEC, in conjunction with the Adsil company conducted a multi-week study at a commercial property near the west coast of Florida. A 10-ton package heat pump was selected and sensors and data loggers were used to collect data for two weeks prior to cleaning and coating. Data was then collected for two weeks postcleaning. The units were then cleaned and coated per Adsil protocol. Data was then collected for a final two weeks. In conjunction with this test, MACTEC conducted our standard test procedure using the spreadsheet, condenser heat rejection, and Service Assistant methodologies. The results of these tests and comparisons may be seen in Appendix D. Task 3: Measure the Change in EER of HVAC Units in the SEQL Area After establishing the protocol for measurement of HVAC efficiency in Tasks 1 and 2, measurement of the EER of 45 HVAC units in the SEQL area was conducted pre- and posttreatment. Prior to treatment MACTEC graded the units using our spreadsheet calculation. Task 4: Develop a Tool for Prediction of HVAC Degradation MACTEC developed a spreadsheet-based tool for predicting the degradation of HVAC equipment based on objective data. This spreadsheet can be used by a facility owner or operator to estimate the degradation of air-cooled HVAC equipment based on objective data inputs. The algorithms used in this spreadsheet were correlated to the actual measured change in efficiencies of the HVAC units pre- and post-Adsil treatment. Task 5: Utility Bill Verification of Savings MACTEC determined that it would not be possible to use utility bills at the tested facilities for determination of electric consumption savings. There were many reasons for this, including an inability to collect utility bills for some of the facilities. Adding to this difficulty was the fact that

P:\EEG\Energy\EPA Adsil Project\Final Report\EPA Adsil Final Report with edits - v2.doc

MACTEC

Application of Adsil in the NC/SC Charlotte Area

many of the facilities shared a common meter. Shared metering masks the effect of the efficiency improvements since the savings would be attributed to facilities with units being treated as well as facilities with no units being treated. A third difficulty is attributed to an inability to collect a minimum of 12 months of bills posttreatment. Application of Adsil was completed in June of 2004, requiring collection of bills until June of 2005 to acquire 12 months of usage; however, this was not feasible based on schedule requirements of the project. In many cases the units were coated in two phases several months apart, rendering a meaningful comparison nearly impossible as 12 months of utility bills would need to be collected prior to any units being treated and requiring 12 months of bills to be collected after the last unit was coated. There would be 6-8 months of bills between events which would have to be disregarded. A fourth and final difficulty was that some facilities had only a small percentage of their total tonnage cleaned and coated. In these cases it would be impossible to measure savings on the utility bills. Even without the aforementioned difficulties, it would be difficult to use utility bill savings as a significant measuring tool in an experiment such as this one. The reason is in our experience the total amount of energy consumed by compressors and condensing units in the type of facilities in this pilot typically account for approximately 30% of the total electricity consumption. Based on measurements pre- and post-treatment, the typical energy savings with Adsil is around 10%. This HVAC savings would equate to an overall utility savings of 3%, a value very difficult to capture in utility bill comparisons due to natural fluctuations of 10% to 20% from weather and usage variations from one year to the next. Therefore, MACTEC used actual efficiency measurements for the 45 units in the SEQL area and three units outside the SEQL area to create the tools and form the conclusions presented in this report.

3. EER Measurement Procedures Initially there were 150 units included in the proposed SEQL area sample. In calendar year 2003, prior to MACTEC’s involvement, 75 of these units were coated with Adsil. EPA and MACTEC decided to determine the efficiency of as many of these remaining units as possible for the allocated budget. Traditional efficiency measurements of HVAC units require multiple temperature sensors, humidity sensors, kW sensors, and flow sensors to feed data to data loggers over a period of time, typically 1-2 weeks, and then repeat the data collection post-HVAC modification. Data is compared, analyzed, trended, and efficiency changes over a wide range of operating temperatures (ambient and inside) are recorded and efficiency changes are determined. It is easy to see why this methodology, while accurate, is expensive, and would have limited the number of HVAC units being evaluated to a small percentage of the number being treated. MACTEC proposed a different methodology requiring a one-time EER determination, pre- and post-Adsil treatment, for each unit. Three different methodologies were used, ranging from simplest to most complex. Results of the tests are provided in Section 5. A description of each of the procedures is provided below:

3.1

Spreadsheet Calculation

MACTEC developed a spreadsheet calculation to estimate the degradation of condenser coils. The spreadsheet uses a compilation of objectively acquired data (see Figure 3-1) including coil age, dirt accumulation, bent and smashed fins, degree of corrosion, presence of coil coating, and fin-tube attachment to estimate the degradation in efficiency of coils. Results were obtained from this procedure on a total of 45 units and the ton-weighted average degradation was calculated. Post-treatment, units were again evaluated and the EER degradation was compared to the pretreatment estimation. The difference in the values was recorded as the EER improvement. This method is the easiest to use but was determined to be the least accurate. It fails to take into account the effects of low refrigerant charge and other variables not visible in a site inspection. Its accuracy is also dependent on the algorithms used to project the EER based on the input. These were later refined, as described in Section 7 of this report.

3.2

Condenser Measurement

The second method used in EER calculation was a straight-forward condenser power consumption and heat rejection calculation. For this method, a Fluke 41 meter was used to measure actual power consumption of the condenser (total power of the condenser fan, compressor(s), and blower motor if a package unit). Heat rejection of the condenser was measured by determining the available flow area of the condenser, measuring the entry air velocity into the condenser, and measuring the change in temperature of the air flow across the condenser. Inaccuracies in this procedure include a calculated air flow higher than actual due to the coil restrictions, a measured air flow impacted by the presence of wind, and compressor heat rejection being included in the EER calculation. As a result, the EERs of the equipment using this methodology were on average almost twice what is expected (due in large part to the inclusion of the coil and fin obstructions in the available air flow area). However, as the compressor heat and available flow area were not germane to the comparison of before and after EER values (they cancel one another out), no effort was made to determine the values of these constants and subtract them from the equations. Every effort was made to minimize the impact of wind, but in some cases the tests were thrown out because the wind velocity was sufficient to impact our measurements. Ambient temperatures, return air temperature, and return air humidity were also recorded. Manufacturer’s data was then used to “adjust” the measured EER at actual conditions to an EER at ARI conditions of 95 degrees dry bulb (ambient temperature) and 67 degrees wet bulb (evaporator temperature). In cases where the supply air cubic feet per minute (cfm) was not available, MACTEC used the value most closely approximating a value of 400 cfm/ton in the manufacturer’s data.

3.3

Service Assistant Measurements

The third method used in EER determination was the employment of a Service Assistant as available from Honeywell Controls. This tool has five sensors for measuring the liquid pressure (downstream of the condenser coil but upstream of the expansion valve) or the discharge from the compressor; the suction pressure before the compressor; the suction temperature before the compressor; the liquid temperature after the condenser; and the ambient temperature. Supply air temperature and humidity and return air humidity are measured via separate instrumentation (not provided with the Service Assistant) and entered into a hand-held personal digital assistant (PDA) which provides the interface. Software on the PDA includes input for Copeland compressor models, or for the capacity and EER of the compressor for compressor models other than Copeland. Using the supplied input and the measured values, the efficiency index, capacity index, and power index are determined by comparing inputs with compressor tables stored in the proprietary software. These values could be calculated manually but the software does it quickly

and reliably with what MACTEC believes to be accurate results. A detailed description of the Service Assistant is provided in Appendix E. MACTEC believes that this method provided the most reliable results. Disadvantages of this method include disassembly of the HVAC units for access, thorough knowledge of HVAC equipment and circuitry for proper location of sensors, and EPA certification in order to attach refrigerant hoses to active HVAC equipment. Total instrumentation cost for methods 2 and 3 are considered to be approximately similar.

4. Testing Procedure Repeatability and Accuracy Achieving repeatable and accurate results is integral to the success of the HVAC efficiency measurement process. Many variables impact the measurement of the efficiency of an HVAC unit. These variables include outdoor air temperature (typically an increase in outdoor air temperature (OAT) decreases the efficiency); return air wet bulb temperature (generally higher wet bulb temperatures result in higher efficiencies); blower air flow rate (constant for these control tests); condenser air flow rate (increased after application of Adsil and generally decreases with air density increase); electrical measurements (power consumed is dependent on voltage, current, load factor, and power factor); and the presence or absence of low temperature ambient controls on individual units (simulate harsh conditions and decrease efficiency). In addition to these variables the instruments used are accurate to within a small error band with additional error being potentially introduced by the reading of the instruments. Measuring the capacity and power consumption of a dynamic piece of equipment involves professional judgment at times in conjunction with the methodology being employed. In order to minimize the magnitude of the errors associated with our protocol, MACTEC selected two units to use in a baseline study. Unit 1 is a 14-year old Carrier 5-ton split-system considered to be in good condition relative to its age. Unit 2 is a two-year old Carrier heat pump considered to be in excellent condition. Unit 1 Protocol This unit was evaluated 17 times prior to the Adsil application and the initial assessment is shown in Figure 4-1. The ambient temperature ranged from 64 degrees to 92 degrees F and the return air wet bulb temperature varied from 53 degrees to 59 degrees F during the testing period from April 2004 through July 2004. The blower air flow was held constant and the condenser air flow was observed to increase after Adsil treatment. The complete test results are presented in Appendix B. Three testing procedures were used in each of the 17 evaluations. The first procedure was the condenser test measurement described in Section 3.2. The second and third tests compared the compressor-specific Service Assistant test to the generic Service Assistant test. The generic test uses a generic compressor curve to determine the operating efficiency of a condenser based on the measurements described in Section 3.3. The compressor-specific test uses the actual compressor model of the identified piece of equipment to determine the operating efficiency. At the time of our study, only Copeland compressor models were available in the software. As many different compressor brands were encountered in our study it was decided that it would be necessary to compare the results of using a generic compressor with the results of the actual compressor model.

Application of Adsil in the NC/SC Charlotte Area

This unit was cleaned with a garden hose prior to initiation of pre-Adsil testing. After completion of pre-testing, the unit was cleaned and coated per Adsil protocol on August 3, 2004. Post-Adsil testing began at this time and continued through August 23, 2004. Twelve tests were conducted post-treatment and comparisons were made to the pre-treatment results. Condenser Heat Rejection and Power Measurement The protocol for this procedure is described in Section 3.2 of this report. Per this procedure, the power consumption was observed to increase as temperature increased, as shown in Figure 4-2 and Figure 4-3. It may also be seen in these two figures that the slope of the curve post-Adsil treatment is steeper than the pre-treatment curve suggesting that power consumption on this tested unit increased after treatment. The intercept for this phenomenon occurs at approximately 88 degrees F in Figure 4-3. A comparison of the measured EER values using this procedure shows great variation prior to Adsil application. EER values ranged from 3.5 to 7.5 in the 70-95 degree temperature range. This variation is due primarily to very inconsistent fan flow measurements prior to the Adsil treatment, as may be seen in Table 4-1. The average flow rate was measured to be 0.66 kilogram per second (kg/sec) with a range of 0.40 kg/sec to 0.94 kg/sec. Post-treatment the fan flow rate averaged 1.13 kg/sec with a range between 1.11 kg/sec and 1.16 kg/sec. Flow post-treatment was very consistent and uniform. The average EER gain using this methodology was determined to be in excess of 70% as shown in Table 4-1 for all temperatures and 49% for tests conducted at 85 degrees and higher. However, the high variation of the flow rates pre-treatment may invalidate the results of this protocol for this unit. Figure 4-4 shows a very large increase in EER post-treatment with a trend of the EER improvement to decrease post-treatment with increasing ambient temperatures. Figure 4-5 also shows a large increase in EER post-treatment with a trend of the EER to increase slightly posttreatment (with increasing ambient temperatures) when only tests 85 degrees and higher are considered. Service Assistant Test Description for Generic Compressor Model The results for this procedure are summarized in Table 4-2. The accuracy and repeatability in the tests improved with an increase in OAT using this procedure. At temperatures below 85 degrees, the data had greater scatter. For instance, in the generic tests the range of achieved efficiency as a percent of theoretical efficiency was between 80% and 102%. However, at temperatures of 85 degrees and higher, the range can be observed to be restricted to between 86% and 90% efficient. Similarly, in the post-treatment tests the range is 86% to 99% at temperatures 73 and above. At temperatures 87 degrees and higher, the range is 89% to 99% efficient. It was interesting to note that the greatest efficiency improvements occurred at the harsher conditions and at lower ambient temperatures there appeared to be little benefit from the treatment process.

Application of Adsil in the NC/SC Charlotte Area

Figure 4-6 shows the EER improvement associated with the Adsil process as measured with the Service Assistant generic compressor over the temperature range from 73 to 92 degrees F. The average EER improvement measured with this process is 4.4% and the average capacity increase is seen to be 5.1% in Table 4-1. When temperatures 85 degrees and above are considered, the improvement in EER is seen to be 5.0% but the capacity increase is less than before with a 3.6% increase. Table 4-2 and Figure 4-7 show these results. Service Assistant Test Description for Copeland Compressor Model The second test employs the actual Copeland compressor model currently in use on the unit. Comparing these results in a similar manner as before, the EER as a percent of the theoretical EER is seen to vary between 79% and 103%. The accuracy and repeatability in these tests also increased with an increase in OAT. At temperatures below 85 degrees, the data had greater scatter. At temperatures of 85 degrees and higher, the range can be observed to be restricted to between 81% and 85% efficient. Similarly, in the post-treatment tests the range is 83% to 96% at temperatures 73 and above. At temperatures 87 degrees and higher, the range is 92% to 96% efficient. It was interesting to note that the greatest efficiency improvements occurred at the harsher conditions and that at low ambient temperatures there appeared to be little benefit from the treatment process. Figure 4-8 shows the EER improvement associated with the Adsil process as measured with the Service Assistant Copeland compressor over the temperature range from 73 to 92 degrees F. The average EER improvement measured with this process is 6.1% and the average capacity increase is seen to be 6.0% in Table 4-3. When temperatures 85 degrees and above are considered, the improvement in EER is seen to be 5.0% but the capacity increase is less than before with a 3.6% increase. Table 4-4 and Figure 4-9 show these results. Summary of Test Results for Unit 1 All three test procedures showed a measurable increase in EER for Unit 1. Figure 4-10 shows change in EER after Adsil treatment for all three procedures. Consistent trend lines are observed when comparing the generic compressor curve test to the Copeland compressor test although the generic test underestimates the Copeland test efficiency gains. The condenser test in this figure shows a much larger increase in EER over the temperature range of 73 degrees to 92 degrees. Figure 4-11 presents the results of tests at 85 degrees and higher. These three curves are approximately parallel and indicate that the EER gains are higher for all three tests at higher temperatures. The condenser test continues to overestimate the gains because of the poor condenser air flow measurements during pre-treatment testing.

Figure 4-12 shows the variability in measuring the efficiency index of the unit pre-treatment over the temperature range of 73 degrees to 92 degrees. Figure 4-13 shows the same indices for the posttreatment unit. Results of this inspection show more uniform results after Adsil treatment. Figure 4-14 shows the indices for temperatures of 85 degrees or higher. Inspection of these graphs indicate that the efficiency index, a measure of the actual efficiency divided by the benchmark efficiency of the unit when new, increases with increasing temperatures. This increase is observed to be more pronounced after the Adsil application. Unit 2 Protocol This unit was evaluated eight times prior to the Adsil application. The ambient temperature ranged from 83 degrees to 92 degrees F and the return air wet bulb temperature varied from 54 degrees to 57 degrees F during the testing period from May 2004 through August 2004. The blower air flow was held constant and the average condenser air flow was observed to increase after Adsil treatment. The complete test results are presented in Appendix C. Figure 4-15 provides the initial assessment of the unit prior to Adsil treatment. Two testing procedures were used in each of the eight evaluations. The first procedure was the condenser test measurement described in Section 3.2. The second test was the generic compressor Service Assistant test. The generic test uses a generic compressor curve to determine the operating efficiency of a condenser based on the measurements described in Section 3.3. This unit was not cleaned prior to initiation of pre-Adsil testing. After completion of pre-testing, the unit was cleaned and coated per Adsil protocol on August 3, 2004. Post-Adsil testing began at this time and continued through August 31, 2004. Seven tests were conducted post-treatment and comparisons were made to the pre-test process. Condenser Heat Rejection and Power Measurement The protocol for this procedure is described in Section 3.2 of this report. Per this procedure the power consumption was observed to increase as temperature increased, as shown in Figure 4-16 and Table 4-5. It may also be seen in these two figures that the slope of the post-Adsil treatment curve is less than the pre-treatment curve suggesting that power consumption on this tested unit decreased after treatment. The intercept for this phenomenon occurs at approximately 84 degrees F. A comparison of the measured EER using this procedure shows great variation prior to and after Adsil application. EER values ranged from 7.6 to 11.2 for all temperature ranges before application and from 9.7 to 13.9 after application. This variation is due primarily to very inconsistent fan flow measurements as may be seen in Table 4-5. The average pre-application flow rate was measured to be 3.91 kg/sec with a range of 3.33 kg/sec to 4.63 kg/sec. Post-treatment the fan flow rate averaged 4.47 kg/sec with a range between 4.07 kg/sec and 4.92 kg/sec.

The average EER gain using this methodology was determined to be 17% for all tested temperatures as shown in Table 4-5. The variations of the flow rates tend to invalidate the results of this protocol for this unit. Figure 4-17 shows the trend of the EER to increase post-treatment with increasing ambient temperatures. Service Assistant Test Description for Generic Compressor Model The results for this procedure are summarized in Table 4-5. The Service Assistant test for Unit 2 showed an average operating efficiency of 96% for tests conducted prior to Adsil application. For these tests the efficiency index (EI) ranged from 95% to 98% and tended to increase with increasing ambient temperature. After application, Unit 2 had an average operating EI of 97%. The post-treatment range varied from 94% to 99% and tended to increase with increasing ambient temperature. The EER for Unit 2 had an average increase of 1% over the range of ambient conditions tested. Figure 4-18 shows the linear profile of the EER over this range and suggests that the unit performance (for pre- and post-Adsil applications) tends to converge around 83 F. The average Service Assistant capacity for pre- and post-Adsil™ applications decreased from 4.18 to 4.16 tons of cooling over the range of tested ambient conditions. The capacity measured tends to converge with increasing ambient temperature and has an average difference of negative 0.54%. The Service Assistant capacity measurement results are presented in Table 4-5. Summary of Test Results for Unit 2 Both test procedures showed a measurable increase in EER for Unit 2. Figure 4-19 presents the results of tests at all temperatures. The results show an increase in EER % change for the Service Assistant test with increasing ambient temperature, and a decrease in % EER change for the condenser test with increasing ambient temperatures. Figure 4-20 shows the variability in measuring the efficiency index of the unit for pre- and posttreatment over the tested temperature ranges. Inspection of these graphs indicate that the efficiency index, a measure of the actual efficiency divided by the benchmark efficiency of the unit when new, increases with increasing temperatures. This increase is observed to be more pronounced after the Adsil application. Conclusions-Units 1 and 2 Test results at temperatures of 85 degrees or greater are considered to be more accurate and viable for the process. The Service Assistant methodology was determined to be the most accurate method for measuring the EER of HVAC equipment.

Comparison with Data Logger Evaluation Traditional measurements of HVAC efficiency have been conducted by collecting data over an extended period of time. This method is believed to be the most accurate for measuring true operating efficiency of HVAC equipment, if the equipment is instrumented properly and sensors are accurate. Ideally, actual air flow and enthalpy changes across the evaporator will be collected and compared to the true power required to produce this cold air flow. Actual power measurements require that the voltage, amperage, and power factor be measured. In the comparison test performed at a commercial property in Clearwater near the Florida west coast, a Carrier 12-1/2-ton, dual-compressor package unit was chosen. Instrumentation of this unit was performed by a third party and the analysis of the data was also performed by a third party. This report is included as Appendix D in this report. The third party testing began on April 27, 2004 with the unit, RTU-2, being instrumented. On May 5, 2004 the unit was cleaned and coated per standard operating procedures of the owner. On May 19, 2004, the unit was cleaned and coated per the Adsil process. Data collection was conducted from April 27 through May 31, 2004. Unfortunately, the actual power was not measured, only the amperage; constant values of 0.85 for power factor and 208 volts for the voltage were assumed and used to estimate the power. Capacity measurements were not made although the data could be used to determine capacity if compressor curves and tables were incorporated in the calculation procedure. The unit had dual compressors which further complicated the measurement process since the cycling of the second compressor had significant impacts to both the power consumption and the condenser efficiency. Refrigerant temperature drop across the condenser, ambient temperature, and refrigerant low and high side pressures were recorded; however, capacity measurements of the condenser were not provided by the third party study. Consequently, EER values were not determined by this third party study complicating the comparison process. The study did provide a multiple linear regression model to determine the daily energy variation with ambient temperature for the unit pre-and post-treatment. Based on the results of this comparison, the energy savings resulting from the treatment process were 3.9%. MACTEC performed our standard Service Assistant and condenser efficiency determinations for this same unit. By using jumper cables on the panel board we manually controlled the compressor operation to energize both the first and second stage during our testing. We did pretreatment testing on May 13 (ambient temperature of 78 degrees) and post-treatment testing on July 21 (ambient temperature of 88 degrees). The data and results of this test may be seen in Appendix D. The Service Assistant test showed a 20.6% increase in EER and the condenser test showed a -5.9% change in efficiency.

Conclusions The low ambient temperature pre-test (78 degrees) during MACTEC’s pre-treatment test has been shown to have the potential to skew test data (see the Unit 1 Baseline Study in Section 4 of this report). For this reason MACTEC believes that the results of our Service Assistant test are not reliable for this site. The condenser test was conducted on a roof where there were measurable breezes present, compromising the integrity of the flow measurements. The third party evaluation predicted a 3.9% savings in energy consumption but used assumptions which, in MACTEC’s experience could skew the range of predicted savings by as much as 150%, giving a potential range of between -2% and 10% as the bounds on savings. MACTEC does not think that conclusive results regarding this comparison were obtained.

5. Measurements in EER The majority of the units evaluated in this study were under preventive maintenance programs. As part of these programs, coils are reported to be regularly cleaned. No specific cleaning of the coils was performed by MACTEC or Adsil prior to commencement of pre-treatment testing. Many of the units were graded out to be very clean according to MACTEC’s site inspection, supporting the claims for regular coil cleanings. The impact of cleaning alone on the performance of these units is not addressed in this report. In previous sections of this report it was determined that the Service Assistant testing methodology was the most accurate and reliable form of instantaneous efficiency measurement procedure. This section of the report will address the results of EER measurement in the SEQL area. Unless otherwise specified, results recorded here are based on the Service Assistant methodology. Initially there were 150 units included in the proposed SEQL area sample. In calendar year 2003, prior to MACTEC’s involvement, 75 of these units were coated with Adsil, effectively eliminating them from the subject population. MACTEC inspected each of the remaining 75 units and successfully completed testing on 45 of these units. The reasons for not testing the other 30 units included the size (either too large or too small for the instruments we were using); lack of electrical power disconnect at the unit; and inability to get the unit(s) to operate. Many of these units contained a single compressor and circuit. These units were the most straight-forward to test and data was collected and analyzed as described in the baseline tests. Other variations included multiple compressors with a common condenser, evaporator and power source; dual compressors in a single package unit with each compressor having a dedicated condenser but sharing the same evaporator circuit and power; and dual compressors sharing a common condenser, evaporator, and power disconnect. A description of how each of these types of equipment was analyzed is presented below. Multiple Compressors, Common Condenser Circuit Many of the package Trane units encountered at York Technical College possessed this configuration. Two or more compressors discharged into a common manifold which went into a single condenser coil. When only one stage was energized, the efficiency of this type of unit is higher than when both compressors are energized. All power measurements were made at the local disconnect and included all operating compressors and condenser fans as well as the blower. In most cases all compressors were energized during both pre- and post-treatment testing. The recorded tonnage was equal to the tonnage of the active compressors. All pre- and post-treatment tests were conducted with the same compressor configuration operating. If conditions could not

Application of Adsil in the NC/SC Charlotte Area

be replicated in the post-treatment test, the data was marked invalid and was not used in this report. Dual Compressors, Dedicated Condenser Many of the York package units encountered at the Monroe Aquatic Center possessed this configuration. A single package unit contained two independent circuits housed in separate compartments with individual condenser fans and condenser housings with an intertwined evaporator circuit. These units shared a single power source. In some cases both compressors were energized and both circuits were independently measured and analyzed. In other cases only one circuit was energized. Pre- and post-treatment tests were conducted on the same number of circuits so as to ensure reliability of test measurements. Recorded tonnage was the nameplate value of the unit. In most cases both circuits were energized. Multiple Compressors, Shared Condenser Some of the units, including those at the York Technical College Library, had this configuration. In the event that only one stage is energized the condenser may work more efficiently than if both compressors are energized since the rejected heat from one circuit is not partially absorbed by the 2nd circuit as when both are energized. Pre- and post-treatment tests were conducted identically and in most cases both circuits were energized. Results-All Tests A total of 395 tons of HVAC equipment was tested in this sample of 45 units over a temperatures range of 70 to 96 degrees. The average increase in EER is presented in Table 5-1. The most significant number presented in the table is the increase in EER for the ton-weighted average. This value is seen to be 9.9% with a standard error of 1.5%. Results-Valid Tests at All Temperatures The validity of 15 of the tests was questionable due to several changes in conditions which were considered to be significant. These included nine (9) units with low refrigerant charge; one (1) unit which had refrigerant added after the first test; and five (5) tests with differing condenser and compressor operation. After eliminating these conditions, 30 tests were deemed valid representing a total of 287 tons of HVAC equipment tested over a temperatures range of 70 to 96 degrees. Table 5-2 summarizes the results of these 30 tests. The ton-weighted average EER improvement was determined to be 11.3% with a standard error of 1.8%. Results-Valid Tests at Literature Temperatures The validity of 15 of the tests was questionable due to tests being conducted at temperatures below those published in the performance data for the HVAC equipment. Different manufacturers rate their equipment over different temperature ranges with data being available for all of the units at temperatures of 85 degrees and above. Data was available at temperatures above 75 degrees on only three of the units and at temperatures above 80 degrees on only four of

the units. The most rigorous presentation of results requires that the results of these tests be eliminated since the determination of efficiency below the supplied data requires assumptions and extrapolations which may or may not be accurate. Additionally, test results in our baseline testing indicate that results are more significant when ambient temperatures exceed 85 degrees. After eliminating these conditions, 15 tests were deemed valid representing a total of 107 tons of HVAC equipment tested over a temperatures range of 85 to 94 degrees. A summary of these test results is provided in Table 5-3.

Application of Adsil in the NC/SC Charlotte Area

The increase in EER varied from a low of 9.9% in the Service Assistant test for all units to a high of 30% using the condenser test methodology on the same sample. It is MACTEC’s opinion that the test results from the Service Assistant tests conducted within the range of manufacturer’s published EER values provide the most reliable prediction of energy savings. The increase in efficiency of the units in this study is therefore estimated to be 12.3%. Complete results are provided in Appendix F. Figure 5-1 graphically depicts the change in EER based on the Service Assistant measurements on this sample.

Application of Adsil in the NC/SC Charlotte Area

6. Projected Energy Savings A total of 150 units in the SEQL area were cleaned and coated with Adsil representing a total of 2,545 tons of HVAC equipment. Based on MACTEC’s measurement of the change in EER, an improvement in efficiency of 12.3% is expected in this population. Appendix G contains the calculation details and assumptions but for convenience the key elements are repeated. The National Oceanic and Atmospheric Administration (NOAA) lists the cooling degree days (CDD) for the Charlotte area at 1,648. This number represents the amount of time that the temperatures are above 65 degrees with each degree above 65 being weighted heavier than the one before. Twenty-four hours of a 66-degree temperature represent one CDD; conversely, one hour of 89 degree temperature also represents one CDD. The American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE) suggests that the number of Full Load Equivalent Operating Hours (FLEOH) of a piece of equipment is roughly equal to 80% of the CDDs. Using these inputs and others detailed in Appendix G, MACETC estimates that the application of Adsil to this population will result in an annual energy savings of 461,400 kilowatt-hours (kWh) and an annual cost savings in excess of $37,000. These energy savings result in lowered production from power plants and should, consequently, result in decreased emissions. However, because of the complexities of the power transfers over the power grid, it is difficult to verify or quantify pollution benefits and to do so is beyond the scope of this project. A tool for projecting energy savings at an individual facility or group of facilities is provided in Figure 6-1. Required inputs are highlighted in yellow. Providing data to these fields will automatically estimate annual energy and cost savings for a facility or facility group.

7. Estimated Degradation in HVAC Performance The estimation of air conditioning condensing unit performance degradation was based on a combination of objective input factors. The development of degradation prediction equations was based on empirical data we collected from testing in this program. MACTEC has previously found that degradation of HVAC equipment is influenced by many factors, including compressor wear, evaporator coil fouling and deterioration (resulting primarily in increased equipment run time and decreased capacity) and condenser coil degradation (resulting in a decrease in efficiency and an increase in power consumption). It is inherently difficult to predict equipment degradation over time. This is due in part to the difficulty in conducting a statistically significant study that controls or measures the large number of variables involved (compressor type, age and condition; condenser coil coating and condition; evaporator coil condition; indoor temperature and humidity conditions; under/overcharge of refrigerant; ambient weather conditions; and quality of equipment installation to name a few). To begin the process, nameplate data for each of 45 units being tested was field-collected and the efficiency of the unit when new was determined from manufacturer’s literature at a range of ambient conditions. MACTEC then measured the efficiency of each HVAC unit and determined the degradation in EER, compared with published data at the same conditions (ambient temperature and entering wet-bulb temperature) when new. A spreadsheet was developed which weighted various condenser conditions, including age, coil cleanliness, fin condition, fin-tube attachment, and corrosion. These categories are objectively graded by algorithms contained in this degradation prediction tool, shown in Figure 7-1. The results of the spreadsheet EER degradation prediction model was compared with the results of the Service Assistant measurements for the two sample groups: Valid Test Results, and Valid Test Results at Literature Temperatures. The spreadsheet model predicted an EER degradation of 11.49% compared with a Service Assistant degradation of 11.50% (ton-weighted average) and 10.31% (unit average). These results are presented in Appendix H. A second comparison was made with the results compiled from the summary tests of the population of units contained in the tests performed within the realm of literature published temperatures. In this case, the spreadsheet model predicted an EER degradation of 10.45%. The Service Assistant measurements resulted in an EER degradation of 13.14% (ton-weighted average) and 11.00% (unit average). These results are also presented in Appendix H.

The impact of various factors on the degradation of the unit are included in Appendix H. It is of interest to note that the age of the unit had little impact on the degradation of the coil (see Figure 7-2). Figure 7-3 graphically depicts the comparison of spreadsheet predicted EER degradation with actual measured degradation. This must be differentiated from the degradation of the unit as a whole because the scope of this project was confined to the recoverable portion of the EER due to Adsil treatment and did not address other contributing factors (compressor wear, evaporator degradation, refrigerant charge, etc.) which would not be impacted by condenser coil restoration. The fin condition and the dirt factor were observed to have the greatest impact on the decrease in performance, as shown in Figure 7-4 and Figure 7-5. Corrosion was observed to have a negative impact on the degradation of these units (see Figure 7-6); however, this may be misleading due to the almost complete lack of corrosion present in this population. Because the corrosion was minimal, other contributing factors controlled the degradation resulting in an apparent increase in EER when compared with corrosion factor as a stand-alone attribute. In aggressive environments or corroded coil units, this attribute would be expected to contribute to the decrease in performance. A comparison was also done to compare the EER Degradation vs capacity. Figure 7-7 shows that the larger units had greater degradation. This has a measurable impact on the comparison of the unit average degradation as compared with the weighted-average degradation. Further discussion on this issue will be presented in Section 8. There is a large variance in the data which is shown by low correlation coefficients for each of these comparisons. This may result in a potentially large error when a single HVAC unit is evaluated using this spreadsheet. However, this error should be normalized when used in larger populations resulting in a more accurate prediction of population EER degradation. This position is supported by the close correlation in EER population degradations (Spreadsheet vs Service Assistant methodologies) as discussed earlier. The accuracy of this tool has not been tested in significantly different climactic areas and there may be additional attributes which need to be considered in these cases.

8. Statistical Significance The results of the SEQL area testing were evaluated to determine the statistical significance of the study. This statistical testing was based on individual unit results; however, the EER improvements realized for the ton-weighted average were greater than for the unit average. A clearly defensible statistical method for evaluating units on a ton-weighted average was not easily discerned so it was decided to measure the significance based on a unit average and apply the results to the ton-weighted average approach. For each unit with both pre- and post-Adsil treatment EER results, the % difference in efficiency {100 x (EER, post-treatment – EER, pre-treatment)/EER, pre-treatment} was tabulated. Thus a positive change indicates an efficiency improvement. This data set (% Change in EER) was tested to determine if it exhibited a normal distribution. Statistical tests were performed in SYSTAT 10 (SPSS, Inc. 2000), and the test for normality was Lilliefors and the level of significance selected was 0.05 (indicating 95% confidence that the data were drawn from a normal population). If the data passed the test of normality, then the ‘t’ test was used to determine whether the average improvement was significantly greater than zero. This procedure is equivalent to performing a paired ‘t’ test on the two (pre- and post-) data sets. The significance was evaluated at a level of 0.05. In fact all data sets exhibited significant improvement with significance less than 0.01, indicating 99% confidence that Adsil treatment resulted in an improvement in efficiency. If the % Change in EER data sets did not follow a normal distribution, then the nonparametric equivalent of a paired ‘t’ test, the Wilcoxon signed rank test, was used to determine the effect of Adsil treatment. All data sets showed an improvement in EER post-Adsil treatment, when compared with pre-treatment EER. The model results are presented in Appendix I. The relationship between EER improvement and unit capacity (tons) was demonstrated in Section 7 and shown in Figure 7-7; therefore ton-weighted averages are expected to exhibit similar improvement as the results obtained from individual unit comparisons, and ton-weighted improvements are also expected to be statistically significant. After determining that each data set exhibited significant improvement, the average and standard error for each data set was determined, as well as the upper and lower confidence intervals of the average improvement. These results indicate typical improvements that may be expected in various populations, as well as the range in potential improvements.

9. Summary of Results and Conclusions MACTEC evaluated the impact of Adsil application to 45 HVAC units in the SEQL area and to three units outside the SEQL area. The results of this evaluation show that the Adsil treatment can be expected to improve the efficiency of existing HVAC units by approximately 12% based on the ton-weighted average method used in this project. The data was statistically evaluated and determined to be significant at the 99% confidence level. Utility bill analysis was determined to be an inappropriate measurement tool for EER changes and therefore actual efficiency measurements for each HVAC unit were performed. Three tests were used including a calculation method, a power and capacity measurement, and a refrigerantbased measurement using the Service Assistant as available from Honeywell Controls. Two baseline studies were conducted to establish the accuracy of each testing protocol and which involved repeated tests on two units. Repeatability in measurements was demonstrated in these tests and it was determined that the Service Assistant instrument provided the most repeatable and accurate measurements of HVAC EER. The generic compressor curve used for many of the SEQL area tests was found to underestimate the actual savings demonstrated in the pilot baseline study tests. The condenser test methodology was generally less accurate but showed greater increases in EER as a result of the Adsil treatment. A degradation prediction tool for HVAC units was created in this pilot program. This spreadsheet-based tool was calibrated against actual EER measurements and was found to be very accurate in predicting the EER degradation of a population of HVAC units in the SEQL area. An energy savings projection tool was also created based on the results of this study. This tool can be easily adapted by facility owners and operators to estimate their energy savings, dollar savings, and possibly avoided pollution emissions as a result of the application of Adsil to aircooled HVAC equipment. This tool estimates that annual dollar savings for the 150 units coated in the SEQL area will exceed $37,000 based on a blended electric rate of $0.08 per kWh. MACTEC believes that this product demonstrated significant savings for air-cooled HVAC equipment.

10. Recommendations MACTEC recommends that the units in this study be evaluated for EER improvements on an annual basis. The instantaneous results form the Adsil treatment indicated that the EER improved 12%. There is no data currently available to support or refute that these improvements will be maintained. It would be very valuable to conclusively identify the long-term impact of the product on HVAC efficiency.

EPA Adsil Evaluation Commercial 5-Ton System Tests

Appendix D Eckerd’s and MACTEC

Eckerd Rooftop Units Two rooftop units on an Eckerd drug store in Clearwater, Florida were instrumented by ADSIL, prior to a routine condenser cleaning (per standard operating procedures), and followed later by cleaning and coating using the Adsil treatment. The testing/cleaning schedule for the units was as follows:

Date April 27, 2004 May 5, 2004 (8:00 AM – 4:00 PM) May 19, 2004 (9:30 AM – 2:00 PM) May 31, 2004

Event Units instrumented and data collection begins Condensers cleaned using standard methods (per SOP) Condensers cleaned and coated using ADSIL treatment Data collection ends

Eight data points were collected at 10-minute intervals for each unit. Data collected included refrigerant temperature entering and leaving the condenser, refrigerant suction and discharge pressures, ambient temperature, and current for each of the three phases on the unit’s main electrical service. The current measurements were converted to power (assuming a constant power factor of 0.85) by:

Power (kW ) =

208 × 3 × Avg ( Ia, Ib, Ic) × 0.85 1000

Figure 1 displays the observed operating patterns of the two units during the monitoring period. The units displayed two typical operating powers near 8 kW and 15 kW, corresponding to first and second stage cooling operation. With the exception of a few hours where unit #2 operated the fan without any cooling1, the units operated the first stage compressor nearly continuously. The second stage compressor is observed to cycle on during the afternoon hours, coincident with the peak cooling load. The bottom plots are shade plots of the unit power. On the shade plot each day is represented by a vertical strip consisting of 144 10-minute data records. Periods of high power consumption are shown by darker shades of grey. Periods of missing data (such as where the units were being cleaned and coated by Adsil) are shown in bright white. The shade plot reveals that unit #2 operated in second stage cooling more frequently than unit #1. Periods where unit #1 was observed to be off (May 4-7 and May 27-30, midnight to noon) are readily observed.

In mid-May there were several hours with an operating power of 3 kW for this unit, a typical value for the supply fan on this size unit.

Figure 1. Rooftop Unit Operating Patterns

The following figure displays the observed condenser performance across the three periods. The data were averaged to hourly values to reduce the amount of scatter. No significant difference was observed between any of the periods. Most significant is the lack of any impact on either the saturated discharge temperature or liquid temperature leaving the condenser. These two parameters tend to have the largest impact on any increase in efficiency from condenser treatment. Also shown is the saturated suction temperature variation with ambient. Again, little change can be observed between the three periods, indicating that no change would have occurred in the supply air temperature.

Figure 4 and Figure 5 displays the daily energy variation with ambient temperature for each unit. The high degree of cycling operation between first and second stage cooling observed required summing the power data collected to daily data for analysis purposes. To assess the impact of the Adsil coating on the daily energy, a multiple linear regression (MLR) model was developed. The model incorporated a dummy variable to describe the impact of the coating (dummy = 1 for the Adsil period, dummy = 0 for the baseline period). Also shown on the plot are the t-ratios for the regression coefficients. The t-ratio describes the statistical significance of each coefficient. Coefficients with t-ratio with an absolute value greater than 2.0 indicate that the coefficients are statistically significant at the 95% confidence interval.

Figure 5. Unit 2 Daily Energy Variation with Ambient

The regression coefficients indicate that after the Adsil coating was applied, compared to the baseline, unit #1 used 35.6 less kilowatt-hours per day and unit #2 used 46.8 less kilowatt-hours per day. Annual savings were determined by applying the regression model to daily temperature data for Tampa, FL from the Department of Energy typical meteorological year data set (TMY2). Savings calculations assume no cooling operation when the average daily temperature is less than 50°F (15 days/year). Unfortunately, the t-ratio for the dummy variable (the savings coefficient) was not greater than 2.0, indicating that the savings were not statistically significant. Table 1. Annual Impact From Adsil Coating

Unit Unit #1 Unit #2

Baseline Energy Use (kWh/year) 384,402 439,142

Energy Use After Adsil Coating (kWh/year) 371,942 422,753

Savings (kWh/year / %) 12,460 / 3.2% 16,389 / 3.9%

Statistically Significant (t-ratio > 2.0) No No

A visual inspection of the daily energy data indicates that the standard cleaning had no impact on the energy consumption of the units. In fact, for unit #2 energy consumption appears to have slightly increased.

Appendix G Energy Savings Calculations

Appendix G- Energy Savings Calculations Increase the Life and Performance of Condenser Coils The outdoor environment can be harsh on heat transfer surfaces. The application of the Adsil corrosion inhibitor will decrease the environmental damage to the condenser coils. As such, the life and performance of the coils is increased. This protection is easily applied to equipment. Facility: SEQL Area 150 Units ECP Savings:

16. ABSTRACT

This report contains the results of a study in the Charlotte, NC/Rock Hill, SC region to evaluate the benefits of a new coating called Adsil. It was conducted as part of the SEQL Project (Sustainable Environment for Quality of Life), an integrated environmental improvement project in the 15-county NC/SC region surrounding Charlotte, NC. Previous studies have shown that, when Adsil is applied to air conditioner units, it can bring the efficiency of that unit virtually back to that of a new unit, as well as prevent agerelated efficiency loss, saving electrical power and early replacement costs. The ability to model expected energy savings with Adsil is beneficial and transferable to other communities. Energy savings reduce costs, limit the need for new generating capacity, and could under certain circumstances benefit air quality. The report includes two tools: 1) A degradation prediction tool (spreadsheet-based) calibrated against actual EER measurements and found to be very accurate in predicting the EER degradation of a population of HVAC units in the SEQL area. 2) An energy savings projection tool created based on the results of this study. This tool can be adapted by facility owners and operators to estimate their energy savings, dollar savings, and potentially avoided pollution emissions as a result of the application of Adsil to air-cooled HVAC equipment. 17.KEY WORDS AND DOCUMENT ANALYSIS a.
