Carnot s theorem is the principle that states the limits on maximum efficiency that the heat engine can obtain and also defines that the efficiency depends on the difference between hot and cold temperatures.
but an ideal refrigerator is basically a reverse carnot engine because all processes in refrigerator are reversible and so energy is not transferred due to friction ,turbulence,etc and all reversible engines that operate between the same two heat reservoirs have the same efficiency.
Its efficiency is called the coeffiecint of performance(COP)
COP=benefit/cost=QC/W
