The condenser of a home refrigerator is commonly underneath the appliance; thus, the condensing refrigerant exchanges heat with household air, which has an average temperature of about 21°C. It is proposed to reconfigure a refrigerator so that the condenser is outside the home, where the average yearly temperature is about 10°C. Discuss the pros and cons of this proposal. Assume a freezer temperature of −18°C, and an actual coefficient of performance 60% that of a Carnot refrigerator.
