Refrigerant 134a is the working fluid in an ideal vapor- compression refrigeration cycle that communicates thermally with a cold region at -10°C and a warm region at 9bar. Saturated vapor enters the compressor at -10°C and liquid leaves the condenser at 30°C. The mass flow rate of the refrigerant is 0.08 kg/s. Use compressor efficiency = 80% Determine (a) the compressor power, in kW, (b) the refrigeration capacity, in tons, (c) the coefficient of performance T 30°C -10°C 3 4 2 P₂=9 bar 1 -To-26°C -299 K
