PROBLEM TO BE SOLVED: To provide an air-conditioning system which operates in a plurality of air-conditioners each having a compressor for conditioning air in one target space, in which an energy consumption efficiency of the entire system is improved.SOLUTION: A plurality of air-conditioners 21-29 includes: a user-side heat exchanger for exchanging heat between air in a room which is an air-conditioning target space and a coolant; a heat source-side heat exchanger for exchanging heat between air in a shared space and the coolant; and respective compressors 41-49 for compressing coolant circulating in the user-side heat exchanger and the heat source-side heat exchanger. When the air-conditioning capacity of two or more of the plurality of air-conditioners 21-29 are within a predefined range, a part of the compressors in the air-conditioners in which the compressor is in operation is stopped.SELECTED DRAWING: Figure 2 【課題】１つの空調対象空間の空調が各々に圧縮機を有する複数の空気調和機で行われる空気調和システムについて、全体としてのエネルギー消費効率の改善を図る。【解決手段】空気調和機２１〜２９は、空調対象空間である部屋の空気と冷媒の熱交換を行う利用側熱交換器、共通空間の空気と冷媒の熱交換を行う熱源側熱交換器及び利用側熱交換器と熱源側熱交換器を循環する冷媒を圧縮する圧縮機４１〜４９を有する。複数の空気調和機２１〜２９のうちの２つ以上について空調能力が所定範囲に入ったときに、圧縮機が駆動されている空気調和機のうちの一部の圧縮機を停止させる。【選択図】図２
