HW4P3 (20 pts) Mar An R-22 vapor-compression refrigeration system is serving 2 evaporators of 15 TR at -20 C and 25 TR at 0C and. The condenser temperature is 40 C. The vapor leaves the two evaporators are superheated by 10 C while the refrigerant leaves the condenser is subcooled to 30C and is throttled to the two intercooler. The system is using mu both stages. Determine: compressor with isentropic efficiency of 75% in frighrough multi-stage expansion valves and flash (a) The mass of the erant through each evaporator. (b) The compressor power. (c) The coefficient of performance. PM EST 11, 2023
