Question
Refrigerant vapor enters into the compressor of a standard vapor compression cycle at () and leaves the compressor at (). It leaves the condenser at (). The COP of the cycle is ___________
Correct answer
5.5 to 5.5
Solution
Given enthalpies for the standard vapor compression cycle:
Compressor inlet (state 1):
Compressor outlet (state 2):
Condenser outlet (state 3):
In a standard cycle, the expansion process is isenthalpic, so .
The Coefficient of Performance (COP) is:
Compressor inlet (state 1):
Compressor outlet (state 2):
Condenser outlet (state 3):
In a standard cycle, the expansion process is isenthalpic, so .
The Coefficient of Performance (COP) is:
