Abstract
A cycle-side system ( ) is formed by duct connecting a compressor ( ), a heat exchanger ( ), a demoisturizer ( ), and an expansion device ( ) in that order. The compressor ( ) 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 ( ), thereby being cooled. Water vapor in the cooled, compressed air is removed in the demoisturizer ( ). The demoisturizer ( ) 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 ( ) to change into low-temperature air. The low-temperature air is supplied into a room. On the other hand, the heat exchanger ( ) is fed exhaust air cooled in a humidifying cooler ( ). Further, in the heat exchanger ( ), a latent heat of vaporization of moisture supplied by a humidifying part ( ) is also utilized for cooling of the compressed air.
