Energy Performance Ratio of Heat Pump Calculator

Energy Performance Ratio of Heat Pump formula is defined as a measure of the efficiency of a heat pump system, which indicates the amount of heat energy delivered per unit of electrical energy consumed, providing a benchmark for evaluating the performance of heat pumps in refrigeration and air conditioning systems is calculated using Theoretical Coefficient of Performance = Heat Delivered to Hot Body/Work Done per min. To calculate Energy Performance Ratio of Heat Pump, you need Heat Delivered to Hot Body (Q_delivered) & Work Done per min (W_{per min}). With our tool, you need to enter the respective value for Heat Delivered to Hot Body & Work Done per min and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

In this formula, Theoretical Coefficient of Performance uses Heat Delivered to Hot Body & Work Done per min. We can use 3 other way(s) to calculate the same, which is/are as follows -

• Theoretical Coefficient of Performance = Heat Extracted from Refrigerator/Work Done
• Theoretical Coefficient of Performance = 1/(Compression or Expansion Ratio^((Heat Capacity Ratio-1)/Heat Capacity Ratio)-1)
• Theoretical Coefficient of Performance = (Temperature at Start of Isentropic Compression-Temperature at End of Isentropic Expansion)/((Polytropic Index/(Polytropic Index-1))*((Heat Capacity Ratio-1)/Heat Capacity Ratio)*((Ideal Temp at End of Isentropic Compression-Ideal Temp at End of Isobaric Cooling)-(Temperature at Start of Isentropic Compression-Temperature at End of Isentropic Expansion)))
