So…How does Smartcoolachieve 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 onTemperature reaches cut out, so the

compressor switches off

Cooling Theory

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

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

How do the ESM™ and ECO3™ 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 ECO3™ have no discernable impact on conditioned space temperature.

Smartcool TechnologyResult:

The ESM™ and ECO3™ increase the efficiency of the compressors by causing the refrigeration or A/C system to operate at a higher suction pressure.

The ESM™ and ECO3™ 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
