an ammonia system supplies chilled brine for a 10 ton load at 0F, a 2 ton load at 20F, and 4 ton load at 35F and must operate at a -10F, suction temperature. Compare the theoretical power requirements with that for three separate F-12 compressors using direct expansion. Condesing os 80 F with 10F sub-cooling, saturared vapour enters the compressor.

The catalog for a refrigerant 22, four cylinder, hermetic compressor operating at 29 r/s, a condensing temperature of 40, and an evaporating temperature of -4 shows a refrigerating capacity of 115 kW. At this operating point the motor (whose efficiency is 90%) draws 34.5 kW. The bore of the cylinders is 87 mm and the piston stroke is 70 mm. The performance data are based on 8 of subcooling of the liquid leaving the condenser. Compute (a) the actual volumetric efficiency and (b) the compression efficiency.
