RESULTS PRESENTATION, TESTS ABOUT AIR CONDITIONING

EQUIPMENT MADE IN METAPLUS (BEPENSA- COCA-COLA) IN MERIDA,

YUCATAN, MEXICO.

MERIDA, YUCATAN

AUGUST 2006

Objective

The purpose of this document is to present the results of the test made by Grupo Energético Mexicano

in the unit YORK, serial number NFYMD37370 of 7.5 tons, treated with our MaxR 100 additive and

located in the Human Resources area in Metaplus, in the city of Merida, Yucatan.

The unit is 7.5 tons. The objectives of the test were:

Increase the equipment´s useful life by increasing it´s oiling (lubrication).

Reduce it´s Energy consumption.

Increase the skills and speed of cooling, using less energy.

After making the test, we conclude that the three objectives have been accomplished, demonstrated

by measurements taken before and after the use of our additives.

II. Test description

Two devices were installed to measure the temperature, they measured every 3 minutes during a time

line before and after the application of MAXR 100, using the ASHRAE 37-1988 procedure as a guide.

Output, Return, environmental and exterior temperatures were measured. The Energy used by the

equipment during the process in the same period of time was measured as well.

During a period of 7 days of measurement before and after the test, we looked for a segment of three

days, during which certain conditions such as the external temperature were kept as similar as

possible between the two periods. This was made to give more consistency to the test.

For analysis reasons, when PRE is mentioned, we will be referring to the measurements made before

the application of MAXR; and when using POST, we will be referring to the measurements made after

treating the equipment with MAXR.

III. Test development

The differences demonstrated in the results show that there are big differences in the unit’s operation,

comparing the PRE and POST periods. The cooling skills of the unit have increased, cooling faster and

in a more efficient way, using less energy.

The comparison period was from the 14th to the 17th of June for the PRE period and from the 12th

to the 15th

of July for the POST period. During this two periods the external temperature was similar.

Average the POST period was 2 degrees higher than the PRE period.

GRAPHIC OF EXTERNAL TEMPERATURE

USEFULL LIFE OF THE EQUIPMENT

The first analysis is about the use of the equipment. In a summary of 610 analyzed

cycles, we count how many times were the equipment’s compressors on by measuring

the energy consumption. In the PRE period compressors were on 91.64% of the time. In

the POST period they were on only 53.94% of the time.

We can conclude that the equipment is extending its useful life by keeping its

temperature and turning on 40% less of the times, as a consequence it will as well

reduce reparation needs. This is an effect of the importance of lubrication (oiling), it

allows it to work easier.

ENERGY SAVING

The next results are about the energy consumption on the PRE and POST periods,

(Metaplus rates in July 2007 and a sales price of 75usd. per oz).

We could find a 35% save in its potential consume in KWH between PRE and POST

periods, improving conditions and reducing effort. With a price of 65 American dollars

per oz, the pay-back time is one year and 12 days. This application assures that the

We have considered that Metaplus Works with a rate above 100KW. In the case of realizing the same tests in lower rates, the result

will be the following:

RATE LOWER THAN 100KW = 10.61 MONTHS GENERAL USE RATE = 4.08 MONTHS

THERMAL CONDITIONS AND ENERGY

The internal temperature was kept between 21.20 °C and 23.97°C in both periods, with

an average of 22.68°C.

In the analysis of this tables we can conclude the following:

As we could see, The output, return and exterior temperatures were higher in the POST in

comparison to the PRE period, but the internal temperature remained in 22°C and the

equipment showed savings in its consumption.

This situation demonstrates that the unit has recovered its skills and speed of cooling,

the equipment has now a more efficient operation, which allows it to have better results

with less effort. This is the result of two conditions: A significant increase in the lubrication

(oiling) of the equipment, which allows it to work in a mechanically efficient way and the

thermal improvement in its coils.

IV. Conclusions

1. The unit presented savings of 35% in KWH consume.

2. The unit increased its life by reducing 37.7% its own use, because of its lubrication.

3. The pay-back time of the investment in the equipment would be of 12 months in the

highest rate (100kw), of 10 months in a rate lower than 100 kw and of 4 months in the

general use rate.

MAXR 100 PERFORMANCE TEST 365 TON YORK SCREW CHILLER

What is MAXR 100? Manufacturer’s definition: MaxR 100 is an inter-metallic compound. The treatment process requires the removal of existing refrigerant oil in equal proportion to the amount of MaxR 100 to be installed. During the integration period, as MaxR 100 is bonding to the metal, existing oil fouling is removed and a permanent bond of the inter-metallic compound is created on the metal surfaces. As a result, MaxR 100 brings the HVAC or Refrigerant unit back to spec in efficiency producing a dramatic energy savings while improving overall operating efficiency.

Information Provided for Documentation of Test:

The existing air conditioning system for Silverado High School consisted of two 365 ton Chillers complete with adequate numbers of Temtrol Air Handlers to maintain comfort levels for the entire school complex. The original design and installation was intended for each Chiller to run alternately and independent of one another. Over time, the gradual degradation of efficiency for both units made it necessary to operate both units simultaneously, with one another, to meet the cooling needs of the building. Running both units at the same time not only increases the utility costs, but places a much higher demand on the operating system as the design had originally intended. One of the main contributing factors in efficiency loss is a phenomenon called oil fouling. As the oil fouling takes hold of the interior surfaces of the Chiller, the heat transfer properties are impaired to the extent that the capacity of the Chiller to produce cooler water is lowered. Air Handlers are devices that are equipped with a set of coils that accept cool water from the Chiller. Fans blow air across the coils of circulating cool water and pass directly to the area needing cooling. The fans usually blow all the time to keep the air in a re-circulating mode. The temperature of the water being supplied to the cooling coil is controlled by various thermostats, pumps, and valves. The Air Handlers were not monitored as part of the Test Procedure. Specifically for the Engineering Services Department of the Clark County School District, this section presents a summary of all the significant test conditions from the MaxR 100 treatment of one of the three-hundred-sixty-five ton YORK SCREW CHILLER (referred to in this test report as “Chiller #2”), located at the Silverado High School in Las Vegas, Nevada. The test procedure is presented in this section as follows:

A. Test unit, dates, location and identification.

1. The original Specifications for Chiller #2 unit is:

York International Model YSDBCBS3-CLA Serial Number: SNBM9216653087B Capacity: 365 Tons Entering (Return) Water Temp 55.01 degF

Leaving (Supply) Water Temp 45.0 degF Design kW/Ton (238 motor kW / 365 ton is .652 kW/Ton)

The performance test on Chiller #2 at Silverado High School was monitored with temperature, humidity and kWh meters in multiple locations. Cold Water Supply and Return and Outside Air Temperatures each were monitored and data was logged in five-minute intervals. A certified state-of-the-art BTU Meter was purchased from Onicon and installed to accurately determine flow rates and various temperatures. During June 23 through June 30, ENV measuring and logging equipment from Climate Automation Systems, 1570 Vivian Lane, Incline Village, NV 89451, was installed in the Chiller unit. All equipment had been tested for accuracy by the manufacturer and certified for use. Installation of all equipment was done by certified technicians from All-Star Air Conditioning and/or AJS Technology, Inc. for Climate Automation Systems in close consultation with Clark County School District personnel. The Outside Air Temperature sensor was installed on the roof of the two-story Silverado High School building above the Chiller room. INSTRUMENTATION: Flow Meter: Onicon BTU/flow meter appropriate for the expected flow range and factory calibrated. This is meter of choice by most equipment manufacturers. Accuracy: 0.5% at calibrated rate, 1% at 10:1 turndown and 2% at 50:1 turndown. 4-20 Ma, 0-5V or 0-10V output over operating range. Temperature sensors were calibrated and be accurate to + or – 0.15 Deg F.

INSTALLATION OF TEST WELLS: Two “hot tap” test wells were installed by CCSD at the appropriate location identified for the test. This location was selected in full accord with the flow measurement device manufacturer’s recommendations for length of straight pipe and other location criteria. The BTU/flow meter was installed, fully consistent with the criteria expressed at: http://www.onicon.com/pdfs/Insertion%20Turbine%20Flow%20Meters%20Selection%20and%20Site%20Selection.pdf DATA AND DATA RECORDING: All instrumentation are self-contained (i.e. independent of the CCSD EMS). Data is recorded at five-minute intervals. Recorded data values represent the

average value of the parameter over the five-minute measurement interval. Data is logged and recorded over the entire logging period and it is

downloadable such that continuous files of five minute readings are created for the PRE and POST test periods. Only data taken during chiller operation for a full five minutes is used to calculate the performance.

Data is recorded continuously at the stated intervals during the PRE and

POST test period regardless of whether the chiller is in operation or not. Data is downloadable and archived or stored in files continuously so that a

continuous record of all five-minute interval data is available. The data is capable of being exported to Excel and other formats for analysis.

Data is downloadable and stored on hardware purchased from Climate

Automation Systems of Reno, Nevada and displayed on software supplied

5

and programmed by them. Connection to the Internet allows observation of current data and accumulated data is monitored by authorized personnel. Remote change of program is limited to only specific personnel. Security restriction was rigidly set and monitored.

CALCULATIONS: Chilled water data calculations is available for: Chiller CHW BTU’s for each five minute period

Chiller CHW flow (gpm) for each five minute period

Chiller average kW over each five minute period

kWh per day PRE = The total kilowatt hours for the PRE installation period per day = the sum of the measured kWh for all of the five minute intervals that the chiller was in operation for that day. Ton-hours per day PRE = The total ton-hours for the PRE installation period per day = the sum of the tons for all of the five minute intervals that the chiller was in operation for that day. The PRE installation kWh/ton = kWh PRE/Ton-Hours PRE kWh per day POST = The total kilowatt hours for the POST installation period per day = the sum of the measured kWh for all of the five minute intervals that the chiller was in operation for that day. Ton-hours per day POST = The total ton-hours for the POST installation period per day = the sum of the tons for all of the five minute intervals that the chiller was in operation for that day. The POST installation kW/ton = kWh POST/Ton-Hours POST DURATION OF TESTING: PRE installation measurements were recorded from July 1, 2008 through July 21, 2008, representing the PRE test period for Chiller #2. MaxR 100 was installed on July 22, 2008, initiating the POST installation test period. CONDITIONS DURING TESTING PERIOD: In order to collect comparative data, the protocol for operation required that Chiller #2 operate solely from 4:00 a.m. through 12:30 p.m. While this protocol

6

was adhered to during the PRE test period of July 1 through July 21, on July 23 (the first POST day following installation of MaxR 100), the protocol was interrupted due to a school function in the building. As was common practice to accommodate cooling comfort levels, Chiller #1 was set to run simultaneously with Chiller #2. This continued through August 3, 2008. On August 4, the test protocol resumed and Chiller #2 ran solo from 4:00 a.m. through 12:30 p.m. In the days following August 4, the building was open to faculty and students in preparation for the school year, as well as public functions. These occupancy levels interfered with the ability to provide “similar circumstance” evaluation for a PRE to POST period comparable analysis. August 4 therefore became the POST date for the purpose of this test report, representing similar PRE period circumstances and protocol of operation. The operating parameter set points; control strategies; settings and control algorithms were recorded at the beginning of the test and were not changed during the entire testing period. During the testing period, no changes were made including changing water or water treatment equipment or practices; cooling tower or tower water treatment modifications or repairs; evaporator or condenser tube cleaning; revisions to condenser or chilled water set-points or set-point adjustment (reset) strategies. CCSD did not perform any maintenance or repairs during the test period that might change factors that impact chiller performance with the exception of permitting All-Star Air Conditioning to change Chiller #2’s oil filter due to an increasing PSI. On June 2, 2008, All-Star Air Conditioning replaced the oil filter in Chiller #2 to prepare for the test. After MaxR 100 was installed, maintenance noticed that the PSI was increasing and called All-Star Air Conditioning to the site. On July 28, 2008, seven days after the MaxR 100 installation, All-Star Air Conditioning had to replace the oil filter which was found to be saturated with debris and was causing the increase in PSI.

7

RESULTS: In order to make a proper and accurate analysis of the data, PRE to POST, a single day comparison was necessary. August 4 was the best possible POST day, as previously explained and July 17 was chosen as the PRE day, as it represented the best display of capacity for Chiller #2, reaching the lowest Supply Water Temperature during the PRE period between the hours of 4:00 a.m. and 12:30 p.m. The single day comparisons of July 17 and August 4 (demonstrated in the incorporated graph), reveal that MaxR 100 enabled Chiller #2 to reach a much lower Supply Water Temperature (the temperature it was originally designed to meet); maintain the lower water temperature and reach that set temperature in less time. The Chiller oil filter explains how these results were achieved and is incorporated as a part of the results. The raw, accumulated data is available upon request. CONCLUSION: Chiller #2 was markedly improved and restored to the original design capacity after being treated with MaxR 100. It is recommended that Chiller #1 be treated with MaxR 100 at the earliest opportunity. If this step is taken, the staff responsible for the operating parameters of the Chillers, can take advantage of the restored operating capacity and reset the units according to original design and spec to maximize their function. A large reduction in operating expenses for Silverado High School should be realized as the two chillers may be alternately cycled. Another benefit to the CCSD, is the tremendous reduction in maintenance and replacement expense. As verified by the necessity to change the oil filter after treatment, MaxR 100 was fully capable of restoring the test unit by cleaning out oil foulings that degrade the efficiency of the cooling unit and shorten the life of the system over time.

The purpose of this guide is to provide customers and specifying engineers with information about how to choose between ONICON's F-1100 Series Single Turbine Meters vs. F-1200 Series Dual Turbine Meters.

How to choose between F-1100 and F-1200 Series Meters: Choosing between the F-1100 or F-1200 Series is primarily related to the amount of straight pipe run available. The straight pipe run requirement for any flow meter refers to the number of "pipe diameters" required before and after the meter. Pipe size, types of upstream obstructions and application type can also be factors in the choice*.

In a location with enough straight run to provide fully conditioned flow, the F-1100 and F-1200 Series Meters will provide the same level of accuracy. The F-1200 Series Meters maintain accuracy in shorter pipe runs by using two contra-rotating turbines to cancel out the effects of swirl in the flow profile, as well as doubling the velocity sampling area.

Selection Criteria: Consider the selection criteria below when choosing between the single and dual turbine configuration. Please note that ONICON's recommendations on straight pipe requirements are conservative to provide accurate results with "real world" piping conditions. Contact ONICON to discuss applications with less than the recommeded straight pipe run.

How to determine the availablestraight pipe diameters: For each application, locate the longest straight, unobstructed section of pipe (no bends, tees, valves, other insertion probes, size transitions).

The longest straight pipe run in inches divided by nominal pipe size in inches equals "diameters of straight pipe."

For closed loop applications, consider both the supply and return lines as possible locations.

What happens inshorter pipe runs?

With ONICON's patented contra-rotating dual turbines, errorcaused by swirl is virtually canceled out, allowing significantlyimproved accuracy when compared to other meter types. For mostinstallations with less than 10 pipe diameters upstream, ourexperience has shown that the dual turbine meter provides accurate, repeatable results. Contact ONICON for installation recommendations on specific applications.

10 pipe diameters upstream, 5 diameters downstream, for themajority of pipe materials and upstream conditions.

What happens inshorter pipe runs?

Recommendation tomaintain specifiedaccuracies:

The error caused by short pipe runs depends on the pipe size, thethe specific type/quantity of obstructions, and their proximity to eachother. Contact ONICON for installation recommendations onspecific applications.

20 pipe diameters upstream, 5 diameters downstream, for themajority of pipe materials and upstream conditions.Will ONICON's single turbine meter perform well using theindustry's standard "10 up/ 5 down" rule? YES, as long as it reallyis the defined "typical" installation with only a single bend upstream and 9 diameters of straight pipe upstream of the bend.

All flow meter types have a requirement for straight pipe runs upstream and downstream of the meter location to maintain the specified accuracy. This is typically expressed as a number of pipe diameters. There is a standard "10 up / 5 down" rule in the industry that many manufacturers refer to as the "typical" installation. This is a little misleading, due to the fact that this "typical" installation allows for only a single 90 degree bend upstream of the meter location, with 9 or more pipe diameters upstream of the elbow! In reality, these conditions rarely exist in a mechanical room. With multiple obstructions upstream, the "10 up / 5 down" rule simply doesn't work for most insertion meter types.

ONICON Recommendations

ONICON has chosen to make conservative recommendations for straight pipe runs that addressthe majority of piping conditions encountered in typical HVAC applications. Following are ONICON's recommendations, along with a discussion on applications where insufficient straight pipe runs exist:

Series F-1100 Single Turbine Flow Meters

GENERAL PRACTICES

1) For best results, install the flow meter in a straight run of pipe,free of bends, tees, valves, transitions, and obstructions, for a dis-tance of 20 pipe diameters upstream and 5 diameters downstream.

2) Longer straight runs may be required in applications where themeter is placed downstream from devices which cause unusualflow profile disruption or swirl, for example, modulating valves ortwo elbows in close proximity and out of plane, etc.

3) If there is insufficient straight run, allow 80% of the run upstreamand 20% of the run downstream. If the total length of straight runis less than 20 diameters, performance may seriously degrade,and consideration should be given to changing to the series F-1200Dual Turbine flow meter.

GENERAL PRACTICES

1) For best results, install the flow meter in a straight run of pipe,free of bends, tees, valves, transitions, and obstructions, for a dis-tance of 10 pipe diameters upstream and 5 diametersdownstream.

2) Longer straight runs may be required in applications where themeter is placed downstream from devices which cause unusualflow profile disruption or swirl, for example, modulating valves ortwo elbows in close proximity and out of plane, etc.

3) If there is insufficient straight run, allow 70% of the run upstreamand 30% of the run downstream. If the total length of straight runis less than 12 diameters, performance may degrade.

Minimum upstreamstraight run distance

Ove Summary of results: Storage and Cooling chambers(cameras)

Lattia!, Rancho Kankabchen November 2006

Attention: Ing. Alberto Barbosa, Service chief, Bepensa Industrial, Mérida, Yucatán, México.

1) OBJECTIVE.- Determine the Energy savings reached by the refrigeration units after being

treated by Grupo Energético Mexicano using the measurement methodology according to the ASHRAE Standard 37-1988 norms.

2) SETTING.- 2 FRIGUS devices in good conditions, feeding a storage Camera, which presented the following values before being treated:

Results Table “PRE”

Maximum Temperature 9.806 °C, Registered at 7:54 AM on 12/09/2006 Minimum Temperature -2.595°C Registered at 1:22AM on 13/09/2006 Average Temperature 2.961 °C (Results measured from the 11th to the 13th of Sept. of 2006). Daily Energy Consumption: 126.46 KWH (Results measured from the 11th to the 13th of Sept. of 2006).

3) DEVELOPMENT OF THE TEST.- Devices to measure Energy were installed in the unit and in the maintenance camera from the 11th to the 13th of Sept. of 2006. We have called this results “PRE” By the end of this phase, 2 oz. of MAXR were installed to each unit. After 50 days, measures were repeated, installing the devices during the same time and days, to have equal operation circumstances. These measures were called “POST”.

4) RESULTS / CONCLUSIONS.-

A Decrease in the consumption of kwh of 49.82% (126.46 pre V.S. 63.46 post).

The real annual savings of the Camera from NOV 06 will be of $21,102.84 without

considering the monthly increase (4%) in electricity tariffs.

The Camera’s temperature had positive variations:

Its new average temperature is -1.877°C, 4.83°C less than in the “Pre” period.

The minimum temperature reached in the “Post” period was -8.940 °C, 6.34°C lower than

the minimum temperature registered in the “Pre” period.

Results Table “POST”

Maximum Temperature 9.060 °C, Registered at 7:54 AM on 12/09/2006 Minimum Temperature -8.940°C Registered at 1:22AM on 13/09/2006 Average Temperature -1.877 °C (Results measured from the 11th to the 13th of Sept. of 2006). Daily Energy Consumption: 63.46 KWH (Results measured from the 11th to the 13th of Sept. of 2006).

After the explanation of our products and the obtainment of results, we can say that

the savings on Lattia’s devices will help the company to:

1) Save $21,102.84 pesos in one year, due to the energy savings in the devices of the

storage Camera.

2) The unit generates better temperatures, with less effort and lower cost.

3) An important increase in the useful life of the units.

4) In case of investing in this application (proposed by Grupo Energético Mexicano) the pay-back will be in 1.26 months. ($1,758.03 savings against $2,200.00 investment).

We can conclude that the project’s objective of saving energy has been accomplished.

*Technical Report*

Casino/Hotel Refrigerated Food Service Cooler

Background: Computerized monitoring was conducted on a food service cooler at the Luxor, a Las Vegas casino/hotel in March of 2001. This cooler provides refrigeration for a portion of the restaurant and food services department. The unit was a double door walk-in unit, three ton refrigeration capacity, using freon refrigerant gas.

Test Procedure:Baseline data was recorded for over two days in order to establish current operating data of the unit. The operating schedule has a built-in 30 minute de-frost cycle every 12 hours.

The additive was introduced into the refrigerant gas flow, carried throughout the system, blending with the refrigerant oil and treating all exposed metal surfaces.Computer monitoring was continued for an additional three days after introduction of additive. Computer data was analyzed to determine the effect of the treatment.

Results:Baseline data shows that the system compressor operates essentially at all times other than the two scheduled half hour periods daily for defrost. Over a 24 hour day, the compressor was off for only 30 minutes (circa), having reached its thermostat set point. (See Figure 1. following page)

Subsequent recorded data shows that over a 10 hour period, the refrigeration system, before the MAXR 100 treatment, was running nearly 97% (circa) of the time, because the thermostat set point was rarely ever attained. However, after the MAXR 100 treatment, the refrigeration system was running only 65% (circa) of the time, because the thermostat set point was attained regularly. (See Figure 2. following page)

Additional 1 hour periods have been a monitored during heavy use times, where therefrigeration system, after the MAXR 100 treatment, was able to shut down for over 40% of the time. (See Figure 3. following page)

Assessment:Significant savings were recorded after introduction of MAXR 100 due to the increased efficiency of the refrigeration system's heat exchangers. Prior to thetreatment, the unit was rarely able to attain set point which would allow the compressor to shut off. After treatment, the set point of the system was attained 30-40 percent of the time, resulting in significant savings in energy and mechanical wear.

Important Note: On 28th July we were informed that the motors of the chiller burnt out and by the time our personnel

arrived at site the maintenance team dismantled the motors and oil has been drained out. The oil quality of ONE

compressor has turned black as shown in the pictures A & B.

Note: The rewound motors re installed on 20th August, 2017 and we installed data logger again on 21st August, 2017. As the lube oil of

two compressors removed during the dismantling of burnt out motors, and they have mixed the oil of the both compressors. With

MAXR100 the compressors have run only for 4 days till these motors failed hence, we let the run the compressors for 14 days and the

IV) Energy Savings & Reduction of Current with MAXR100

a) Reduction in KWH/Hour

Average Energy Consumption in KWH/ Hour without MAXR100 : 14.596 KWH Average Energy Consumption in KWH/Hour with MAXR100 : 11.536 KWH Improvement in kWh/ Hour : 3.06 Kwh Energy Savings with MAXR100 IN % : (3.06/11.536)x 100 = 20.96 %

b) Reduction in Current

Average Current in Amps Pre : 25.42 Amps Average Current in Amps (Post) : 22.06 Amps Improvement in Amps : 3.36 Amps Improvement % in Current (Amps) : (3.36/25.42) x 100 = 13.21 %

6

V) Actual Energy Savings Considering the change in average Ambient Temperatures post MAXR100 installation period.

For calculating the actual savings we need to consider the change in ambient temperatures of pre data period with

the post data period, which is 2.5 Deg C. Any decrease in the ambient temperature will affect the energy consumption of the AC unit. Hence for calculating the actual savings we need to consider COP- Coefficient of Performance principle which is most commonly used method.

COP- is the ratio of heat removed from a system to the energy required to remove the heat. The theoretical maximum is equal to the coldest temperatures of the refrigerant divided by the difference between its coldest and hottest temperatures are expressed in Kelvins. Even the perfect system decreases efficiency with increased outside temperatures, dropping about 2% per Deg C.

Considering 2.18 Deg C decrease in the ambient Temperatures for the post MAXR 100 installation period the

energy consumption has to be INCREASED by 4.36 % during the period.

7

Considering the above we have calculated the actual energy consumption during the post MAXR100 installation period. Total Energy consumption in KWH : 1615 KWH Increase in Energy consumption due to decrease in ambient temperature : 4.36 % Actual Energy Consumption in KWH : (1814 x 4.36)/100 = 70.4 KWH

1615.00 + 70.4 = 1685.4 kWh

Actual average Energy Consumption / Hour on kWh : 1685.4/140 = 12.03 kWh/Hour Actual % of Energy Savings with MAXR100 : (14.596 – 12.03 ) = 2.566 kwh

(2.566/14.596) x 100 = 17.58 %

F) Observations & Conclusions

a) Average Energy Consumption in KWH/ Hour (Pre) : 216.32 Kwh b) Average Energy Consumption in KWH/Hour (Post) : 180.13 kwh c) Difference : 216. 32- 180.13 = 36.19 Kwh /Hour

d) Improvement with MAXR100 in % : (36.19 /216.32) x 100 = 16.73 %

However, the Post MAXR100 the ambient temperature decreased from 27.7 Deg C to 26.29 Deg C (i.e. by 1.41 Deg C)

Actual Energy Savings Considering the change in average Ambient Temperatures post MAXR100 installation period.

For calculating the actual savings we need to consider the change in ambient temperatures of pre data period with the post data period, which is 1.41 Deg C. Any increase in the ambient temperature will affect the energy consumption of the AC unit. Hence for calculating the actual savings we need to consider COP- Coefficient of Performance principle which is most commonly used method.


8

Considering 1.41 Deg C decrease in the ambient Temperatures for the post MAXR 100 installation period the energy consumption has decreased 2.82 % during the period.

Considering the above we have to calculate the actual energy consumption during the post MAXR100 installation period and add the difference to the recorded total energy consumption.

a) Total Energy consumption in KWH : 23219 Kwh b) Increase in Energy consumption due to rise in ambient temperature in % : 2.82 % c) Actual Energy Consumption in KWH : (23219 x 2.82)/100 = 654.7758 KWH

23219 + 654.7758 = 23873.75 Kwh

VI) Energy Savings& Reduction of Current with MAXR100


Actual Energy Savings Considering the change in average Ambient Temperatures post MAXR100 installation period.

For calculating the actual savings we need to consider the change in ambient temperatures of pre data period with the post data period, which is 2.5 Deg C. Any decrease in the ambient temperature will affect the energy consumption of the AC unit. Hence for calculating the actual savings we need to consider COP- Coefficient of Performance principle which is most commonly used method.


7


Considering 2.5 Deg C decrease in the ambient Temperatures for the post MAXR 100 installation period the energy consumption has to be INCREASED by 5 % during the period.

Considering the above we have calculated the actual energy consumption during the post MAXR100 installation period. Total Energy consumption in KWH : 1814.00 Kwh Increase in Energy consumption due to rise in ambient temperature in % : 5 % Actual Energy Consumption in KWH : (1814 x 5)/100 = 90.7 KWH

1814.00 + 90.7 = 1904.7 kWh Actual average Energy Consumption / Hour on kWh : 1904.7/127.5 = 14.938 kWh/Hour Actual % of Energy Savings with MAXR100 in % : (19.318 – 14.938 ) = 4.38 Kwh/ Hour

(4.38/19.318) x 100 = 22.67 %
