Required information Problem 05.087 - Heat exchanger 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 m³/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 0.745 kg/s. 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. The specific heat of air is taken as 1.005 kJ/kg-°C. Problem 05.087.b - Heat exchanger Determine the temperature change of air. (Round the final answer to three decimal places.) °C.
