Introduction to theEnergy Savings ModuleTM
& The ESM ECO³™
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
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
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
The ESM ECO³™ Product Overview
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 ECO3™ is an economical, small-scale application of the same technology used in the ESM™.
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
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
• 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 complianceQuality Assurance: Complies with ISO9001
North America: Complies UL 916 & ULC 22.2 No.205-M1983
Europe (CE): Complies with EN60730 (IEC 730) & EN60950:2000Complies with EMC directive EN55022, EN55024,
89/336/EEC & 93/68/EEC
Australia: Complies with AS2064, AS3100 & AS3260
Impact on Existing Equipment Warranties
So…How do the
ESMTM & ECO3TM achieve savings?
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
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
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.
