To cope with an air backflow generated in ducts, in an air-conditioning system for supplying conditioned air to a plurality of points in a building by using the ducts.SOLUTION: A heat exchanger unit 10 includes a use-side heat exchanger 11. A plurality of ducts 20 are connected to the heat exchanger unit 10. A plurality of fan units 30 suck conditioned air from the heat exchanger unit 10 via the plurality of ducts 20, and supply it to a plurality of flow-out ports 71. In a plurality of distribution flow passages composed of the plurality of ducts 20, the plurality of fan units 30 and the blow-out ports 71 of a plurality of blow-out units 70, a pressure difference sensor 121 being a detection device detects an air backflow progressing toward the heat exchanger unit 10 from at least one blow-out port 71 out of the plurality of blow-out ports 71.SELECTED DRAWING: Figure 1 【課題】ダクトを使って建物内の複数の箇所に調和空気を供給する空気調和システムにおいて、ダクトで生じる空気逆流へ対処する。【解決手段】熱交換器ユニット１０は、利用側熱交換器１１を含む。複数のダクト２０が熱交換器ユニット１０に接続されている。複数のファンユニット３０が、複数のダクト２０を介して熱交換器ユニット１０から調和空気を吸引して複数の吹出口７１に供給する。検出装置である差圧センサ１２１は、複数のダクト２０と複数のファンユニット３０と複数の吹出口ユニット７０の吹出口７１からなる複数の分配流路において、複数の吹出口７１のうちの少なくとも一つの吹出口７１から熱交換器ユニット１０に向う空気逆流を検出する。【選択図】図１
