An indoor pool evaporates 1.512 kg/h of water, which is removed by a dehumidifier to maintain 21C, 70% in the room. The dehumidifier, shown in Fig P12.71, is a refrigeration cycle in which air flowing over the evaporator cools such that liquid water drops out, and the air continues flowing over the condenser. For an air flow rate of 0.1 kg/s the unit requires 1.4 kW input to a motor driving a fan and the compressor and it has a coefficient of performance, QL/ Wc 2.0. Find the state of the air as it returns to the room and the compressor work input.
