Abstract
A compressor ( ), a heat exchanger ( ), a demoisturizer ( ), and an expansion device ( ) are duct connected in that order to form a heat source-side system ( ). The compressor ( ) draws and compresses outdoor air and exhaust air for ventilation. The compressed air is subjected to heat exchange with air for conditioning in the heat exchanger ( ). The compressed air is demoisturized in the demoisturizer ( ). Thereafter, the compressed air is expanded in the expansion device ( ), changes to low-temperature air, and then is expelled to outside the room. On the other hand, the conditioning air is delivered, through an inlet duct ( ), to the heat exchanger ( ). The conditioning air is a mixture of supply air for ventilation and air in the room. The conditioning air is subjected to heat exchange with the compressed air in the heat exchanger ( ), whereby the conditioning air is heated. Further, the conditioning air is humidified in a humidifying part ( ). Thereafter, the conditioning air is supplied into the room for effecting room heating.
