Air-conditioning apparatus

A cycle-side system (20) is formed by duct connecting a compressor (21), a heat exchanger (30), a demoisturizer (22), and an expansion device (23) in that order. The compressor (21) draws in room air and supply air for ventilation and compresses the same. The compressed air exchanges heat with exhau...

More Information
Summary:A cycle-side system (20) is formed by duct connecting a compressor (21), a heat exchanger (30), a demoisturizer (22), and an expansion device (23) in that order. The compressor (21) draws in room air and supply air for ventilation and compresses the same. The compressed air exchanges heat with exhaust air for ventilation in the heat exchanger (30), thereby being cooled. Water vapor in the cooled, compressed air is removed in the demoisturizer (22). The demoisturizer (22) is provided with a separation membrane and separates water vapor in the compressed air without the occurrence of condensation. Thereafter, the compressed air is expanded in the expansion device (23) to change into low-temperature air. The low-temperature air is supplied into a room. On the other hand, the heat exchanger (30) is fed exhaust air cooled in a humidifying cooler (41). Further, in the heat exchanger (30), a latent heat of vaporization of moisture supplied by a humidifying part (42) is also utilized for cooling of the compressed air.
