MULTI-TYPE AIR CONDITIONING DEVICE

PROBLEM TO BE SOLVED: To provide a multi-type air conditioning device capable of executing an internal drying operation with high efficiency and with low power consumption while suppressing degradation of comfort.SOLUTION: A necessary drying capacity of each of indoor units 3a, 3b, 3c is calculated on the basis of a time of a cooling operation executed before stop of the indoor units 3a, 3b, 3c after the indoor units 3a, 3b, 3c stop the cooling operations, a ratio of necessary drying capacity as a ratio of each of the necessary drying capacities of the indoor units 3a, 3b, 3c to the total value of the necessary drying capacities, is calculated, and openings of expansion valves 27a, 27b, 27c are controlled so that a refrigerant is distributed more to the indoor unit 3a, 3b, 3c of high ratio of necessary drying capacity, when the plurality of indoor units 3a, 3b, 3c executing the internal drying operation exist.SELECTED DRAWING: Figure 5 【課題】快適性の低下を抑制し低消費電力で効率の良い内部乾燥運転を実行することが可能なマルチタイプ空気調和装置を提供する。【解決手段】室内機３ａ，３ｂ，３ｃが冷房運転停止した後、室内機３ａ，３ｂ，３ｃの停止前に行われた冷房運転の時間基づいて各室内機３ａ，３ｂ，３ｃの必要乾燥能力を算出し、必要乾燥能力の合計値の中でそれぞれの室内機３ａ，３ｂ，３ｃの必要乾燥能力が占める割合である必要乾燥能力比率を算出し、内部乾燥運転を行う室内機３ａ，３ｂ，３ｃが複数台有る場合、必要乾燥能力比率が高い室内機３ａ，３ｂ，３ｃに冷媒が多く分配されるように膨張弁２７ａ，２７ｂ，２７ｃの開度を制御する。【選択図】図５
