A compressor (21), a heat exchanger (30), a demoisturizer (22), and an expansion device (23) are duct connected in that order to form a heat source-side system (20). The compressor (21) 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 (30). The compressed air is demoisturized in the demoisturizer (22). Thereafter, the compressed air is expanded in the expansion device (23), 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 (43), to the heat exchanger (30). 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 (30), whereby the conditioning air is heated. Further, the conditioning air is humidified in a humidifying part (42). Thereafter, the conditioning air is supplied into the room for effecting room heating.
