Problem 10.008 si refrigerant 22 enters the compressor of an ideal vapor-compression refrigeration system as saturated vapor at -40°c with a volumetric flow rate of 10 m3/min. the refrigerant leaves the condenser at 19°c, 9 bar. determine: (a) the magnitude of the compressor power, in kw. (b) the refrigerating capacity, in tons. (c) the coefficient of performance. (d) the rate of entropy production for the cycle, in kw/k.
