PROBLEM TO BE SOLVED: To provide an air conditioning system capable of improving heat exchange efficiency by using 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 use the air in a ceiling AT for a plurality of heat source side heat exchangers. In a first ventilation part 41 and a second ventilation part 42, the air is ventilated between outdoors 99 and the ceiling AT through a first ventilation port 43 and a second ventilation port 44. A first ventilation fan 46 and a second ventilation fan 47 generate an airflow which enters from the outdoors 99, flows between the first ventilation port 43 and the second ventilation port 44 and is blown out to the outdoors 99. A controller 30 changes a path of the air in the ceiling AT flowing between the first ventilation port 43 and the second ventilation port 44 based on the temperature of the outdoors 99 around 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の熱交換に用いて熱交換効率を向上させることのできる空気調和システムを提供する。【解決手段】複数の空気調和機２１〜２５は、天井裏ＡＴの空気を複数の熱源側熱交換器に用いる。第１換気部４１と第２換気部４２では、第１換気口４３と第２換気口４４を通して屋外９９と天井裏ＡＴとの間で空気が通気される。第１換気ファン４６と第２換気ファン４７は、屋外９９から入って第１換気口４３と第２換気口４４との間を流れて屋外９９に吹き出される気流を生じさせる。コントローラ３０は、天井裏ＡＴの周囲の屋外９９の気温に基づいて第１換気口４３と第２換気口４４との間を流れる空気の天井裏ＡＴ内における経路を変更する。【選択図】図２
