Abstract
A cyclic circuit ( ) is constructed by sequentially connecting an expander ( ), a heat exchanger ( ) and a compressor ( ). A dehumidifying mechanism ( ) is provided for dehumidifying a heat-absorbing air taken in through an inlet duct ( ). An internal heat exchanger ( ) is provided for cooling the dehumidified heat-absorbing air and then supplying it to the expander ( ). The heat-absorbing air expands in the expander ( ) to reduce its temperature. Since the heat-absorbing air has been dehumidified in advance, the moisture thereof does not condense during the expansion thereof. The heat-absorbing air having reached a low temperature through expansion flows into the heat exchanger ( ) and absorbs heat from a room air therein. Thereafter, the heat-absorbing air is compressed in the compressor ( ), regenerates a rotor member ( ) and is then discharged.
