Refrigerationa.) Explain why you can’t cool down your kitchen by leaving your refrigerator or freezer door open with your refrigerator plugged in for an extended period of time.b.) 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 toreconfigure 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.c.)

You have decided now that quarantine is about over to take a trip to Hawaii. You decide to rent a small house that has floor to ceiling windows. It is small so it is one floor. The length and width of the windows are 9m x 14m. There are 4 of them. It is a constant 950F (350C) outside and you really like it 650F(180C) inside. You have an air conditioner that operates at 75 percent Carnot efficiency. The windows are 6cm thick and the rest of the house is well insulated. a) How much electrical energy do you use in a day? b) What is the cooling capacity each day?
