Q103
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
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
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.
