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.) Which is the most effective way to increase the coefficient of performance of a Carnot refrigerator: to increase TC with TH held constant or to decrease TH with TC held constant? Justify mathematically. For a real refrigerator, do…

The winter air conditioning system has a preheat coil, an air washer, and a reheat coil as processing units. It supplies air at 38°C db-temperature to a space maintained at 21°C db-temperature and 13°C wb-temperature. The sensible and latent heat loads on the space are 50 kW and 25 kW, respectively. Of the return air from the space, 40% by dry air mass is discharged to the ambient and replaced with fresh outdoor air at 2°C db-temperature and 95% relative humidity.

H6. An air conditioner in an upper-floor apartment unit is turned on during a hot summer afternoon. If heat can be removed from the interior at a rate of 1.5 kW, estimate the time required to cool the air inside the apartment to its final temperature. Your estimate should create any needed input data and should incorporate factors like the size of the apartment and the behavior of air.
