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 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? Correct Answer Carnot refrigeration cycle

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.
