So… How does Smartcool achieve savings??

 Compressors use 70% of the energy in refrigeration and air conditioning systems.  The cooling cycle is dynamic and changing.  Conventional controls: Measure & respond to fixed temperature values Not responsive to compressor efficiency  Temperature reaches cut in, so the compressor switches on  Temperature reaches cut out, so the compressor switches off Cooling Theory

Heat removal capacity is directly proportional to operating temperature / pressure. As temperature drops so does heat removal capacity.

Cooling Theory Removing the last degree of heat requires double the energy required to remove the first degree of heat.

How do the ESM™ and ECO 3 ™ work?  Cooling efficiency varies over the pressure and/or temperature range  Smartcool technology exploits this characteristic to reduce compressor run time and in so doing reduces energy consumption

Smartcool Technology  The technology causes the system to operate at a higher suction pressure where heat is removed more efficiently, thus requiring fewer operating hours and less electricity to achieve the same temperature.

Smartcool Technology  The ESM™ and ECO 3 ™ have no discernable impact on conditioned space temperature.

Smartcool Technology Result:  The ESM™ and ECO 3 ™ increase the efficiency of the compressors by causing the refrigeration or A/C system to operate at a higher suction pressure.  The ESM™ and ECO 3 ™ reduce 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
