Why do we study the reversed Carnot cycle even though it is not a realistic model for refrigeration cycles?
Why do we study the reversed Carnot cycle even it is not a realistic model for refrigeration cycles.
Explanation of Solution
A reversed Carnot cycle consists of an isentropic and isothermal process. Generally, the reversed Carnot cycle cannot be used an ideal model for refrigeration purpose since the isentropic process needed a maximum operational speed, but the isothermal process needed a very less operational speed.
But this cycle acts as a realistic model against which refrigeration cycles can be related. Also, the coefficient of performance of the reversed Carnot cycle gives the upper limit for the coefficient of performance of a refrigeration cycle which is functioning between the definite temperature limits.
Hence, the reversed Carnot cycle is considered for refrigeration cycles.
