The events of a cascade, split-stage, low temperature refrigerating cycle are as follows; A Freon 12 vapor compression system operates between 0˚F and 100˚F with saturated liquid on the high side of the expansion valve and saturated vapor entering the compressor whose volumetric efficiency is 90 %. An ammonia compression system operates between -60 ˚F and 12 ˚F with saturated liquid entering the expansion valve and saturated vapor entering the compressor whose volumetric efficiency is 88 %. The Freon 12 evaporator serves as the condenser for the ammonia for the ideal cycle and 2 tons of refrigeration. Find a) the displacement of each compressor. b) the total horsepower required for compressor efficiency of 80 %.
