Cop formula for heat pump

WebIt is proposed to install a Heat Pump to supply heating to a large domestic house. The system is to be designed to operate using refrigerant 134a. If the operating conditions of the plant are as follows calculate the Coefficient of Performance (CoP). Operating Conditions:-Refrigerant mass flow rate :- 8 kg/minute WebThe coefficient of performance, COP, is a key characteristic of heat pumps and describes the performance of heat pumps. COP is highly dependent on operating conditions. ... According to the above formula, the maximum achievable COP for T hot = 35 °C (308 K) and T cold = 0 °C (273 K) would be 8.8. But in reality, the best systems are around 4.5.
