10.6 WP Refrigerant 134a is the working fluid in an ideal vapor- compression refrigeration cycle operating at steady state. Refrigerant enters the compressor at 1.4 bar, -12"C, and the condenser pressure is 9 bar. Liquid exits the condenser at 32"C. The mass flow rate of refrigerant is 7 kg/min. Determine a. the compressor power, in kW. b. the refrigeration capacity, in tons. c. the coefficient of performance
