Moist air enters an air-conditioning system as shown in the figure below at T1 = 28°C, ?1 = 85% and a volumetric flow rate of (AV)1 = 0.89 m3/s. At the exit of the dehumidifying section, the air is saturated, ?2 = 100%, and the condensate leaves this section at the same temperature as the moist air. At the exit of the heating section the moist air is at T3 = 24°C, ?3 = 50%. The system operates at steady state, the pressure is 1 bar at all locations, and kinetic and potential energy effects are negligible.
Determine the heat transfer rate for the dehumidifying section, in kw
