A four-cylinder, single-acting R-12 compressor 30 cm x 40 cm runs at 960 rpm. The compressor clearance factor is 0.03 and the law of compression pV1.1=C. The operating pressures for the vapor compression refrigeration system are: 8.47 bar (35°C) and 1.004 bar (-30°C). The refrigerant temperatures are: entering the compressor -20°C, leaving the compressor 50°C; entering the condenser 45°C, leaving the condenser 25°C, entering the expansion valve 30°C, and leaving the evaporator dry saturated. Assuming that heat removed in the compressor is 25 kJ/sec. Calculate: i) The refrigerating capacity ii) The compressor power iii) COP iv) Mass of condensing cooling water assuming the rise in temperature to be 10°C v) Also, tabulate energy balance for 1 kg of refrigerant.
