Clean air conditioning units use far less energy when operating, clean internal and external coils allow a better heat exchange across the coils meaning the compressor and fans have to run far less to give the required output. And increases the COP of your unit (coefficient of performance) this saves you money and helps reduce your carbon footprint!

What is Coefficient of Performance - COP

The Coefficient of Performance - COP - is the basic parameter used to report efficiency of refrigerant based systems.

The Coefficient of Performance - COP - is the ratio between useful energy acquired and energy applied and can be expressed as


COP = Eu / Ea         (2)
COP = coefficient of performance
Eu = useful energy acquired (btu in imperial units)
Ea = energy applied (btu in imperial units)
COP can be used to define both cooling efficiencies or heating efficiencies as for a heat pumps.

  • Cooling - COP is defined as the ratio of heat removal to energy input to the compressor
  • Heating - COP is defined as the ratio of heat delivered to energy input to the compressor

COP can be used to define the efficiency at single standard or non-standard rated conditions, or as a weighted average of seasonal conditions. The term may or may not include the energy consumption of auxiliary systems such as indoor or outdoor fans, chilled water pumps, or cooling tower systems.

  • higher COP - more efficient system

COP can be treated as an efficiency where COP of 2.00 = 200% efficiency. For unitary heat pumps, ratings at two standard outdoor temperatures of 47oF and 17oF (8.3oC and -8.3oC) are typically used.

In the past, air conditioning was thought of as an extravagant luxury, but with rising summer temperatures and increasing quantities of heat-sensitive technology in our homes, workplaces and leisure facilities, most of us are realising that it is rapidly becoming a necessity.
