The refrigerant leaves the evaporator at -20oC and has a condenser pressure of 0.9 MPa. The mass flow rate is 3 kg/min. Find COPR and COPR, Carnot for the same ... The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs. The COP usually exceeds 1, especially in heat pumps, because, instead of just converting wor…

WebAug 5, 2015 · Now we have the “energy out” portion of the formula in watts, and from the manual, we see that the heat pump consumes 2,700 watts to run. This is the “energy in” part of the COP formula. Now we can plug this into the calculation: COP = energy out / energy in. COP = 10,518 / 2,700 = 3.89. Based on our calculations, a four-ton water to ... WebThe coefficient of performance (COP) is the net outcome of an air source heat pump’s Seasonal Energy Efficiency Rating (SEER) and Heating Seasonal Performance Ratio (HSPF). SEER and HSPF are correlated, and if both are high, your air source heat pump will have greater COP.
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.
