PURPOSE:To eliminate discomfort feeling at the time of air-conditioning by flowing air into a room after the outside air flows in a chamber and mixes with the indoor air in a ceiling-buried heat exchanger unit such as in a building. CONSTITUTION:The indoor air flowed in from an indoor inlet 52 is blown from a supply opening 33 of the body from a circulating air blower 51. Further, the air flowed in from an indoor outlet 53 by a ventilating fan 48 are flowed through an exhaust communicating hole 55, passed through a whole heat exchanger 50, flows in a body outlet 39 and is exhausted outside. On the other hand, intake air is flowed through an intake air communicating hole 56 from an inlet 37 of the body by an air inlet fan 47, passed through the whole heat exchanger 50 and flowed in through a chamber 41 through an air supply opening 54 provided in a first partition plate 40. The air is mixed with the air which flows in from an indoor inlet 52 and blown into the room from the supply opening 33 of the body. Thus, at the time of heating air, the temperature is heightened, at the time of cooling air the temperature is lowered and the air is blown in the room by mixing with the indoor air in the chamber 41. |
