The evaporator of a refrigeration cycle is basically a heat exchanger in which a refrigerant is evaporated by absorb- ing heat from a fluid. refrigerant-22 enters an evaporator at 200 kpa with a quality of 22 percent and a flow rate of 2.65 l/h. r-22 leaves the evaporator at the same pressure superheated by 5°c. the refrigerant is evaporated by absorbing heat from air whose flow rate is 0.75 kg/s. determine (a) the rate of heat absorbed from the air and (b) the temperature change of air. the properties of r-22 at the inlet and exit of the condenser are h1 = 220.2 kj/kg, v1 = 0.0253 m3/kg, and h2 = 398.0 kj/kg.
