Question:-
The discharge pressure of the compressor in the refrigeration system goes up due to the
Option (A)
Lower volumetric efficiency of the compressor
Option (B)
Formation of scale in the condenser
Option(C)
Large size of the condenser
Option(D)
Undercharge of the refrigerant
Correct Option:
(A)
Question Solution:
Volumetric efficiency of compressor
h = 1+C-C(P2/P1)1/n
Hence increasing the pressure ratio, volumetric efficiency decreases.
