PROBLEM TO BE SOLVED: To provide an air conditioner capable of suppressing an evaporator from being large-sized although configured to cool air of the evaporator with a cold storage material continuously for a long time during a stop of circulation of a refrigerant.SOLUTION: An air conditioner 10 comprises: a circulation flow passage 20 in which a refrigerant circulates; an evaporator 100 which is provided halfway in the circulation flow passage 20, and cools air through heat exchange with the refrigerant passing through the circulation flow passage 20; a cold storage container 150 which is provided at a position adjacent to a tube 130 that the refrigerant passes through in the evaporator 100, and internally contains a first cold storage material PF1 changing in phase by heat exchange with the refrigerant passing through the tube 130; and a cold storage container 250 which is provided at a position different from the evaporator 100 in the circulation flow passage 20, and internally contains a second cold storage material PF2 changing in phase by heat exchange with the refrigerant passing through the circulation flow passage 20.SELECTED DRAWING: Figure 1 【課題】冷媒の循環が停止した状態において、蒸発器における空気の冷却を蓄冷材によって長時間継続し得る構成としながらも、蒸発器の大型化を抑制することのできる空調装置を提供する。【解決手段】空調装置１０は、冷媒が循環する循環流路２０と、循環流路２０の途中に設けられており、循環流路２０を通る冷媒との熱交換により空気を冷却する蒸発器１００と、蒸発器１００のうち冷媒が通るチューブ１３０に隣接する位置に設けられており、チューブ１３０を通る冷媒との熱交換によって相変化する第１蓄冷材ＰＦ１、を内部に貯えている蓄冷容器１５０と、循環流路２０のうち蒸発器１００とは異なる位置に設けられており、循環流路２０を通る冷媒との熱交換によって相変化する第２蓄冷材ＰＦ２、を内部に貯えている蓄冷容器２５０と、を備える。【選択図】図１
