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).
