2. An R22 operates between evaporator and condenser temperatures of -20 C and 50 C, respectively. The system is to be used in producing 4800 kg of ice at -10C from water at 30C in 24 hrs. Assuming losses to be 30 percent of the heat to be absorbed from the water, determine (a) the mass flow rate, (b) the heat rejected in the condenser, and (c) the power required by the compression
