The condenser of a home refrigerator is commonly underneath the appliance, thus the condensing refrigerant exchanges heat with household air, which averages 70oF. It is proposed to reconfigure a refrigerator so that the condenser is in the garage, where the average yearly temperature is about 50oF. Assume a freezer temperature of 0oF, a minimum temperature difference of 10K for heat transfer, and an actual coefficient of performance of 60% that of a Carnot cycle. Calculate the Coefficient of Performance for both configurations and discuss the pros and cons of this proposal.

condensing refrigerant exchanges heat with household air, which averages 70oF. It is proposed to
reconfigure a refrigerator so that the condenser is in the garage, where the average yearly

pros and cons of this proposal.
Carnot cycle has four reversible processes which make it a reversible cycle. There will be two adiabatic and two isothermal processes. The heat removed inside a refrigerator and work done by compressor ratio is coefficient of performance. This depends on the indoor temperature required and the temperature outside.
