WebThe energy efficiency ratio (EER) of a particular cooling device is the ratio of output cooling energy (in BTUs) to input electrical energy (in watt-hours) at a given operating point. EER is generally calculated using a 95 °F (35 °C) outside temperature and an inside (actually return-air) temperature of 80 °F (27 °C) and 50% relative humidity. WebIn contrast to COP, COSP (Co-efficient of System Performance) is a description of the total (electrical) energy used by a heat pump in relation to the total work done (cooling or heating) by the pump. COSP can therefore be defined as the electrical power in kW used to produce 1 kW of cooling. COSP is expressed as a ratio.
