25. Question
Refrigerant 134a is the working fluid in an ideal vapor-compression refrigeration cycle that communicates thermally with a cold region at 4 C and a warm region at 30 C. Saturated vapor enters the compressor at 4 C and saturated liquid leaves the condenser at 30 C. The mass flow rate of the refrigerant is 0.08 kg/s. Determine (a) the compressor power, in kW, (b) the refrigeration capacity, in tons, (c) the coefficient of performance
