摘要： An air-conditioning apparatus includes a housing having an outside air port, an air supply port, a return air port, and an exhaust port. The air-conditioning apparatus also includes: an outside air passage to make the outside air port and the air supply port communicate with each other; an exhaust air passage formed in the housing in a separated manner from the outside air passage to make the return air port and the exhaust port communicate with each other; an indoor heat exchanger disposed in the outside air passage; the air-sending device disposed in the outside air passage, and configured to generate an air flow directed toward the room from the outside air port via the air supply port and the air supply duct during operation; and an air supply damper being open during the operation of the air-sending device and being closed during a stop of the air-sending device.
