sci.refrigeration-cop Calculator
Calculates refrigeration COP = T_cold/(T_hot − T_cold) for the ideal vapour compression cycle. A refrigerator cooling to 5 °C and rejecting heat at 35 °C has Carnot COP = 9.3 — real systems achieve 2–4 due to irreversibilities in compressor, expansion, and heat exchangers.
Inputs
Evaporator Temp C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Condenser Temp C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Refrigerating Effect Kj Kg
Reference formula or conversion factor shown for context.
Compressor Work Kj Kg
Energy transferred by a force over a displacement (J = N·m).
Results
actual COP
Reference formula or conversion factor shown for context.
Carnot COP (max)
Sample size or count used in the calculation.
relative efficiency
Useful output divided by total input, as a percentage. True 100% efficiency is impossible — losses appear as heat. LEDs: 30–50%. Electric motors: 85–97%. Switching supplies: 85–95%.
heat rejected (kJ/kg)
The value at the specified point or condition.
COP = Q_L / W = T_L/(T_H-T_L)
