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