Arefrigerator removes heat from a refrigerated space at 0°c at a rate of 2.2 kj/s and rejects it to an environment at 20°c. what is the minimum required power input?

The minimum power required by the refrigerator is 161 W to remove heat from a refrigerated space.

Explanation:

To calculate the power required to refrigerate we know that COP of refrigerator is represented as . Given that,

Thus we can say that minimum power required by refrigerator if a refrigerator removes heat to an environment at 20°C from a refrigerated space at 0°C at 2.2 kJ/s is 161W.
