Consider an ideal vapor compression refrigeration cycle. If the throttling process is replaced by an isentropic expansion process

Q. Consider an ideal vapor compression refrigeration cycle. If the throttling process is replaced by an isentropic expansion process, keeping all the other processes unchanged, which one of the following statements is true for the modified cycle?

             (A) Coefficient of performance is higher than that of the original cycle.

             (B) Coefficient of performance is lower than that of the original cycle.

             (C) Coefficient of performance is the same as that of the original cycle.

             (D) Refrigerating effect is lower than that of the original cycle.

Ans: Coefficient of performance is higher than that of the original cycle
