A building freezer that is used to freeze vegetables requires 40 tons of refrigeration to keep the food frozen. The temperature of the freezer is -35°C and the ambient temperature outside the building is 30°C. If the performance of the freezer is 20% of the theoretical best possible cycle, what is the power required to run the freezer. 1 ton of refrigeration is equivalent to 210 kJ/min.

A vapor-compression refrigeration cycle operates at steady state with Refrigerant 134a as the working fluid. Saturated vapor enters the compressor at 2 bar, and saturated liquid exits the condenser at 8 bar. The isentropic compressor efficiency is 80%. The mass flow rate of refrigerant is 7 kg/min. Determine: (a) the compressor power, in kW, (b) the refrigeration capacity, in tons, (1 ton = 3.5168 kW) and, (c) the coefficient of performance, (d) rate of entropy production in kW/K, for the...
