Refrigerant 22 enters the compressor of an ideal vapor- compression refrigeration system as saturated vapor at 2408C with a volumetric flow rate of 15 m3/min. The refrigerant leaves the condenser at 198C, 9 bar. Determine
(a) the compressor power, in kW.
(b) the refrigerating capacity, in tons.
(c) the coefficient of performance.
