An R-22 vapor compression system utilizes liquid to suction heat exchanger in the system. The condenser pressure is 1191.90 kPa and the evaporator pressure is 354.30 kPa. The heat exchanger warms the refrigerant from the evaporator to 5OC. If the compression is isentropic, calculate the COP. Calculate: (a) the mass of refrigerant flow;(b) the refrigerating capacity if the compressor draws in 12 liters per second of R-22; (c)the compressor work and (d) the amount of cooling water in the condenser in kg/hr if ∆t of water is 10OC
