Question

a refrigeration cycle operates between condenser temperature of + 27??c and evaporator temperature of- 23??c. the carnot coefficient of performance of cycle will be

Answer 1

The Carnot coefficient of performance will be 5.

The COP of the cycle is calculated as

COP=$\frac{T_{o}}{T_{k}-T_{o}}$

Here, temperatures are in Kelvin

Plugging the values in the above equation

COP=(-23+273)/((27+273)-(-23+273))

COP=5
