PROBLEM TO BE SOLVED: To provide an air conditioner enabling reliable dehumidification with a user intention indoor machine even in low load.SOLUTION: When at least one indoor machine among a plurality of indoor machines 5a-5d is under cooling operation and the other indoor machines receive a dry operation instruction, an air conditioner controls a compressor 21 so that an evaporation temperature of refrigerant flowing in indoor heat exchangers 51a-51b of the indoor machines, which execute dry operation, is equal to or less than a target evaporation temperature Tes, and thereby a temperature of the indoor heat exchanger can be always equal to or less than a dew point temperature of indoor air, to enable dehumidification.SELECTED DRAWING: Figure 1 【課題】低負荷時であってもユーザの任意の室内機で確実に除湿することが可能な空気調和装置を提供する。【解決手段】複数台の室内機５ａ〜５ｄのうち少なくとも一台の室内機が冷房運転中であって、他の室内機がドライ運転の指示を受けていた場合、ドライ運転を行う室内機の室内熱交換器５１ａ〜５１ｂを流れる冷媒の蒸発温度が目標蒸発温度Ｔｅｓ以下となるように圧縮機２１を制御することで、室内熱交換器の温度が必ず室内空気の露点温度以下となり、除湿を行うことができる。【選択図】図１
