0?. A Freon 12 vapour compression system operating at a condenser temperature of 4DE'C and an evaporator temperature of [PC develops 15 tons of refrigeration. Using the p-h diagram for Freon 12, determine. {a} the discharge temperature and mass flow rate of the refrigerant circulated, {b} the theoretical piston displacement of the compressor and piston displacement per ton of refrigeration, [c] the theoretical horsepower of the compressor and horsepower per ton of refrigeration, {d} the heat rejected in the condenser, and {e} the Carnot COP and actual CDP of the cycle
