Question:

Refrigerant R-12 enters the compressor of an ideal vapor-compression refrigeration system as saturated vapor at -10oC with a volumetric flow rate of 1 m3/min. The refrigerant leaves the condenser at 35oC and 10 bar. Determine
(a) The compressor power, in kW,
(b) The refrigerating capacity in tons and
(c) The coefficient of performance (COPR).
