HW4P1 (20 pts) A two-stage R-22.edu - plant with flash intercooler for food freezing has two-stage compressor with 45 mm bore and 40 mm stroke for all cylinders and the following specifications: LP Compressor: 6 cylinders, 1000 rpm, with a volumetric efficiency of 75% HP Compressor: 4 cylinders, 800 rpm, with unknown volumetric efficiency Find the refrigerating capacity of the plant, the HP compressor volumetric efficiency MEDT. the COP when the plant is operating at a condenser temperature of 40C and an evaporator temperature of -40C. Also, find the interstage pressure using minimum power assumption. Assume saturated vapor at inlet to compressors and saturated liquid at exit from the condenser. The system uses separate expansion valves for expansion to the flash chamber pressure and the evaporator pressure, respectively. es for
