Refrigerant 134a is the working fluid in an ideal vapor-compression refrigeration cycle that communicates thermally with a cold region at -5 °C and a warm region at 35 °C. The vapor enters the compressor at -10 °C,1 bar. The liquid leaves the condenser at 9 bar, 30 °C. The compressor has an isentropic efficiency of 80%. 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, (d) the heat transfer rate to the surrounding space, and (e) "rate of entropy production per cycle" (including compressor, evaporation, expansion vale, and condenser).
