The document introduces the Energy Savings Module (ESM) and ESM ECO3, energy saving devices developed by Smartcool Technology to reduce energy consumption in air conditioning and refrigeration systems. The ESM and ECO3 utilize proprietary software and control algorithms to optimize compressor run times, achieving energy savings averaging 20% without impacting equipment performance or warranties. Case studies on installations in China, Australia, and the Philippines demonstrate annual energy savings ranging from 8,395 to 121,224 kWh.

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

2. Introduction to Smartcool Technology initial developed in Australia by Abbotly Technologies Pty. Ltd. in the mid – 1980’s Smartcool acquired the assets of Abbotly Technologies Pty. Ltd. in 2006 Developing distribution networks throughout the Americas, Europe, Middle East, Asia-Pacific & Australia Proven technology with over 25,000 installations worldwide Member of the TSX Venture 50 in 2007 Winner of the Deloitte Green 15 in 2007

3. What Is The ESM™ ? Microprocessor based energy saving device Air conditioning systems Refrigeration systems Usage (kWh) savings of 10% to 25% No penalty system No change to pre-existing operating criteria No impact on air conditioned space

4. ESM ™ Key Features Retro-fittable product with minimal field wiring or plant down time Self-learning - requires no manual adjustment Always fails to safe Certified product CE Certified UL Certified Remote communications and control

5. The ESM ECO³™ Product Overview

6. ECO³™ Features Two models: Single Channel, for use with a single compressor Dual Channel, for use with two compressors cooling the same controlled space Reduces compressor run times Usage (kWh) savings averaging 20% Interfaces with existing controls No risk to current equipment or effect on manufacturer’s warranty Maintains temperature performance Optimizes the efficiency of the cooling & heating cycles on compressor driven heat pump units The ECO 3 ™ is an economical, small-scale application of the same technology used in the ESM™.

7. ECO³™ Features Displays kWh savings Allows bypass- auto returns to savings when bypass complete Smartcool proprietary software Multiple cable diameter sealed entry IP64 rated for outdoor installations Simple wall mount and product installation

8. Compatibility With Control Systems Compatible with all known control systems since it complements, but does not replace the primary controls 25,000 units installed world wide on many different control platforms ESM™ has RS 485 & RS 232 communication ports which allow for networking of all units on site & connection with PC via LAN or Modem

9. 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

10. So… How do the ESM TM & ECO 3TM achieve savings?

11. COMPRESSOR OPTIMIZATION Designed to work with the existing aircon and refrigeration equipment, along with the current control methodology, to reduce energy consumption When a call for cooling comes from the existing controller, the advanced control module takes over to determine when and for how long each compressor or unloader will run This advanced control technology enable the compressor to maximize the rate of heat removal by optimizing the natural physical properties of the compressor operating cycle

12. Background 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 The example above, uses a +(-) 2.5° C suction temperature differential

13. Background (cont’d) 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 Unfortunately, this increases the mid point temperature from 7.5°C to 8°C.
