  1. Introduction to the Energy Savings Module™ & The ECO³™

  2. Introduction to Smartcool • Smartcool acquired the technology and intellectual property rights in 2006 • Distribution networks throughout the Americas, Europe, Middle East, Asia-Pacific & Australia • Proven technology with over 26,000 installations worldwide • Energy Star Service & Product Provider since 2006 • US Green Building Council Member since 2007 • Member of the TSX Venture 50 in 2007 • Winner of the Deloitte Green 15 in 2007

  3. Features of The ESM™ & ECO3™ The ESM™ and ECO3™ are proven retrofit technologies with the following features: Microprocessor based energy saving devices compatible with air conditioning and refrigeration systems Plant operational time reductions averaging 30% Average usage (kWh) savings of 15% Average demand (KW) savings of 10% Interfaces with existing controls No change to pre-existing operating criteria No impact on conditioned space or chilled water temperatures No risk to current equipment or effect on manufacturer’s warranty

  4. Distinctive Features ofThe ESM™ • Controls up to 8 compressor capacity controllers, in large chillers and rack systems • Enabled for remote network access and multi-unit networking • Capable of slide valve control • Temperature or pressure control-enabled

  5. Distinctive Features ofThe ECO3™ • Economical, small-scale application of the same technology used in the ESM™ • Controls up to 2 compressors in A/C systems and 1 compressor in refrigeration systems • Optimizes the heating and cooling cycles of compressor driven heat pumps • IP64 rating allows outdoor installation • Simple installation can be completed in under 1 hour by a qualified technician

  6. NO Impact on existing equipment warranties Complies with compressor manufacturers specifications for cycling rates Low voltage product with a fuse to protect existing equipment Always fails to safe Standards compliance Quality Assurance: Complies with ISO9001 North America: Complies UL 916 & ULC 22.2 No.205-M1983 Europe (CE): Complies with EN60730 (IEC 730) & EN60950:2000 Complies with EMC directive EN55022, EN55024, 89/336/EEC & 93/68/EEC Australia: Complies with AS2064, AS3100 & AS3260 Impact on Existing Equipment Warranties

  7. So…How do the ESMTM & ECO3TM achieve savings?

  8. Background Majority of controls concentrate on conditioned space temp, chilled water temp or suction pressure Compressors are switched ON in response for cooling and will operate until that demand is satisfied To avoid (short cycling), which will cause damage to compressors, the control bands are usually set with a min. differential of approx. 4 PSI or 2° C.

  9. Background Compressor capacity to remove heat is directly proportional to the operating temperature The higher the controlled temperature, the higher the suction pressure (evaporator temperature), the faster the rate of heat removal When compressor first starts at high limit point it will operate at maximum efficiency with a high suction pressure As the conditioned space temp. is reduced, the suction pressure drops and compressor capacity is reduced Each degree of temperature reduction takes a longer period of time and uses more electricity

  10. Background The example above, uses a +(-) 2.5° C suction temperature differential The table to the right, shows a typical chiller compressor capacity chart for a nominal 40 kWh heat load, showing the time & energy taken per degree of temp. reduction Reducing from 6° to 5°C takes 14.4 minutes and 3.57 kWh The last degree of pull down uses almost twice the energy and time

  11. Background Unfortunately, this increases the mid point temperature from 7.5°C to 8°C. The chart to the right illustrates the percentage of energy used per degree. The last degree of pull down used 28% of the total energy for the cycle

  12. COMPRESSOR OPTIMIZATION The ESM™ and ECO3™ are designed to work with the existing refrigeration equipment, along with the current control methodology, to reduce energy consumption When a call for cooling comes from the existing controller, Smartcool’s technology takes over to determine when and for how long each compressor or unloader will run This advanced control technology enables the compressor to maximize the rate of heat removal by optimizing the natural physical properties of the compressor operating cycle

  13. Compressor Optimization This “Optimization” is done with no appreciable difference to the temperature being controlled

  14. Compressor Optimization • By creating more time where the compressors operate in the higher suction pressure area, the ESM™ & ECO3TM have the compressors run more often when they are more efficient. • By running less, the compressors energy usage is reduced.

  15. Compressor Optimization with the ESMTM &ECO3TM Result: • The ESM™ and ECO3™ increases the efficiency of the compressors by causing the refrigeration or A/C system to operate at a higher suction pressure • The ESM™ and ECO3™ reduces the total run time of the compressors resulting in a reduction of electricity use • Because the compressors are operating more efficiently pre-set controlled space temperature performance is maintained with fewer operating hours and less electricity use

  16. THIRD PARTY VALIDATION Smartcool’s technology has undergone significant independent third party testing, proving its energy saving capabilities. Of particular note are the following tests: Florida Power & Light: The University of Miami conducted extensive testing on behalf of FP&L of the ESM™ over a twelve month period in 2006. The testing showed that the ESM™ reduced kWh usage of the entire air conditioning system by 8.9% – which provides a savings of 13.38% of the kWh usage by the compressors, an annual reduction of 43,660 kWh and a reduction in greenhouse gas emissions of 58,911 lbs. The testing also showed a 10.8% reduction of peak demand which is equated to 6.9 KW in August and estimated to be 422 KW for the year. These savings were achieved with no statistically significant impact on the indoor air temperature and indoor relative humidity. Oak Ridge National Laboratory: ORNL conducted a two phase test of the ESM™ in 2004-2005. The first phase of the test involved the analysis of data collected from an installation on a refrigeration rack in a grocery store. The second phase evaluated the ability of the ESM™ to reduce the electrical consumption of a four compressor roof top unit in a controlled laboratory environment. Test results showed an 11.87% reduction in kWh usage by the compressors in the system and a 2.2% demand (KW) reduction.

  17. Who Uses The ESMTM &ECO3TM?

  18. Navy Exchange - Orlando The Smartcool ESM™ was installed on two Tyler refrigeration racks of a NEX (Navy Exchange) Retail Store in Orlando, Florida. Sainsbury’s Smartcool technology was installed on the refrigeration system of a Sainsbury’s supermarket in Badger Farm, UK. The positive results of this initial project have led to a major roll-out to other Sainsbury’s locations.

  19. Wellcome Tesco The Smartcool ESM™ was installed on the refrigeration system of two Tesco stores in London, UK. Copeland scroll compressors are responsible for the refrigeration in both stores, and the ESM™ was installed to optimize them as part of a larger trial for Tesco. The strong test results led to a wider roll-out of the ESM™ to other Tesco stores. The Smartcool ECO3™ was installed on the air conditioning system of a supermarket in Hong Kong. Coolmatic packaged units are responsible for the air conditioning of the open-front store, and the ECO3™ was installed to optimize these units’ compressors .

  20. What Smartcool can do for you • Energy efficiency retrofits are the fastest, most cost effective way of meeting energy reduction targets • Cooling systems consume at least 15% of the energy used in buildings, making them responsible for a substantial portion of GHG emitted by buildings

  21. What Smartcool can do for you Improve Your Business by E3
