(a)Vapour compression cycle
(b) All of the above
(c) Reversed Joule Cycle Reversed (d)Brayton Cycle​

Answer 1

The coefficient of performance (COP) of a refrigerator (or heat pump) comprised of reversible processes (CARNOT) is always greater than the COP for a sequence of irreversible (real) processes operating between the same high and low temperature reservoirs (regardless of type of devices, working fluid, etc.).
