Coefficient of performance (fridge)
COP = T_c/(T_h − T_c)
Where: COP = Coefficient of performance (fridge), T_c = T_c, Tₕ = Tₕ
Solved example
Given: T_c = 7, T_h = 5
Find: COP_ (Coefficient of performance (fridge))
- Formula: COP = T_c/(-T_c + Tₕ)
- Substitute the values: COP = 7/(5 - 7)
- Result: COP = -3.5
Answer: COP_ = -3.5
Calculator
How to calculate Coefficient of performance (fridge)
- Write down the formula: COP = T_c/(T_h − T_c).
- Note the known values (T_c, Tₕ).
- Substitute them and simplify to find COP_.
- Use the calculator above to solve for any letter.
Frequently asked questions
What is the formula for Coefficient of performance (fridge)?
The formula is COP = T_c/(T_h − T_c), where COP = Coefficient of performance (fridge), T_c = T_c, Tₕ = Tₕ.
