To provide air conditioning equipment which allows for reduction of discomfort feeling of a user even if a refrigerant fill amount is decreased by replacing a refrigerant with a combustible refrigerant.SOLUTION: When a total requirement capacity being a total of requirement capacities of indoor units 5a to 5t exceeds a threshold requirement capacity, a CPU 210 operates several sets of the indoor units corresponding to the threshing requirement capacity, stops the remaining indoor units, and performs indoor rotation control for periodically changing the indoor units to be stopped. When the CPU 210 performs the stopped indoor machine rotation control, the CPU calculates a thermal load of each indoor machine at each prescribed time, and stops the indoor units selected sequentially from the indoor unit which is small in the thermal load.SELECTED DRAWING: Figure 2 【課題】可燃性冷媒に置き換えて冷媒充填量が減少しても使用者の不快感を低減できる空気調和装置を提供する【解決手段】ＣＰＵ２１０は、室内機５ａ〜５ｔでの要求能力の合計である合計要求能力が閾要求能力を超えた場合は、閾要求能力に対応する台数の室内機を運転し残る室内機を停止する。そして、停止する室内機を定期的に変更する停止室内機ローテーション制御を行う。ＣＰＵ２１０は、停止室内機ローテーション制御を実行するとき、所定時間毎に各室内機の熱負荷を算出し、同熱負荷が小さいものから順に選択した室内機を停止する。【選択図】図２
