Refrigeration with highest cop

WebTo calculate the COP of an air conditioner, divide the cooling output (in kW) by the power input (in kW). The higher the COP value, the higher the efficiency of the air conditioner. The formula to calculate COP is as follow: COP = Cooling Capacity / Power Consumption. where, COP = Coefficient of performance, kW/kW. WebMar 29, 2001 · Therefore, refrigeration systems with a high degree of emission are preferred application areas for CO2 as an alternative refrigerant, as long as the energy efficiency, defined as Coefficient of Performance (COP), can be kept at the same level.
