To suppress energy consumption by efficiently sharing the air in an indoor common space other than an air-conditioned space for heat exchange of a plurality of air conditioners.SOLUTION: A plurality of air conditioners 21-25 includes: a utilization side heat exchanger for performing heat exchange with the air in an air-conditioned space; a heat source side heat exchanger in which heat transfer is performed between itself and the utilization side heat exchanger; and a heat source side fan for flowing the air taken-in from a ceiling AT to the heat source side heat exchanger and blows it out to a common space. The plurality of heat source side heat exchangers of the air conditioners 21-25 is arranged in the ceiling AT. A first ventilation fan 46 is arranged in the vicinity of an exhaust port 43 for exhausting the air to the outdoors 99 from the ceiling AT, and it is the ventilation fan which can change an air blowing amount. A controller 30 changes the air blowing amount of the ventilation fan based on the information regarding the temperature of the ceiling AT.SELECTED DRAWING: Figure 2 【課題】空調対象外の屋内の共通空間の空気を複数の空気調和機で熱交換のために効率良く共用して消費エネルギーを抑制する。【解決手段】複数の空気調和機２１〜２５は、空調対象空間の空気と熱交換を行う利用側熱交換器、利用側熱交換器との間で熱の伝達が行われる熱源側熱交換器、及び天井裏ＡＴから取り入れられる空気を熱源側熱交換器に流して共通空間に吹き出させる熱源側ファンを有する。空気調和機２１〜２５の複数の熱源側熱交換器は、天井裏ＡＴに配置されている。第１換気ファン４６は、天井裏ＡＴから屋外９９に空気を排気するための排気口４３の近傍に配置され、送風量の変更が可能な換気ファンである。コントローラ３０は、天井裏ＡＴの気温に関する情報に基づいて換気ファンの送風量を変更する。【選択図】図２
