The evaporator of a refrigeration cycle is basically a heat exchanger in which a refrigerant is evaporated by absorbing 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 o c. the refrigerant is evaporated by absorbing heat from air whose flow rate is 0.75 kg/s. make a sketch of this heat exchanger labeling the inlets and exits for both the refrigerant and the air. then determine (a) the rate of heat absorbed from the air [kw] and (b) the temperature change of air [ o c]. 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
