Common questions
- What is the Heat Pump COP formula?
- Coefficient of performance for heat pump. It sits under Cycles, Thermo engineering in the EngiRef reference.
- What do the symbols in the Heat Pump COP formula mean?
- In Heat Pump COP, COPₕₚ is cop (heat pump); Qₕ is heat delivered in J; W is work input in J; Tₕ is high temperature in K; Tₗ is low temperature in K.
- When does the Heat Pump COP formula apply?
- Heat Pump COP holds under this condition: Carnot COP (maximum possible).
