A refrigeration cycle is a reversed heat engine. Which of the following has the maximum value of the co-efficient of performance (COP) for a given refrigeration effect?
A. Vapor compression cycle using expansion valve
B. Air refrigeration cycle
C. Vapor compression cycle using expansion engine
D. Carnot refrigeration cycle
Answer: Option D
Solution(By Examveda Team)
Carnot refrigeration cycle has maximum COP since carnot is an ideal cycle consisting of reversiable changes at each and every step and hence no losses.This Question Belongs to Chemical Engineering >> Chemical Engineering Thermodynamics
