To simplify a configuration of an air conditioner capable of switching modes among a heating mode, a cooling mode, and a dehumidifying and heating mode.SOLUTION: An air conditioner includes heat generating devices 33, 35, 36, and 37 that generate heat when operated and are cooled by a heat medium, a low temperature heat medium outside air heat exchanger 32 for exchanging heat between the heat medium and outside air, and a heat medium circuit for circulating the heat medium in a low-pressure side refrigerant heat medium heat exchanger 17, the heat generating devices 33, 35, 36, and 37, and the heat medium outside air heat exchanger 32. A first decompression part 80 can switch a state between a state in which the refrigerant radiates heat to outside air by a refrigerant outside air heat exchanger 81, and a state in which the refrigerant absorbs heat from the outside air by the refrigerant outside air heat exchanger 81. When air is cooled by an air cooling heat exchanger 14 and air is heated by air heating parts 12 and 22, a refrigerant flow switching part 16 causes the refrigerant to flow in the low-pressure side refrigerant heat medium heat exchanger 17.SELECTED DRAWING: Figure 1 【課題】暖房モード、冷房モードおよび除湿暖房モードを切り替え可能な空調装置の構成を簡素化する。【解決手段】作動に伴って発熱し、熱媒体によって冷却される発熱機器３３、３５、３６、３７と、熱媒体と外気とを熱交換させる低温熱媒体外気熱交換器３２と、低圧側冷媒熱媒体熱交換器１７と発熱機器３３、３５、３６、３７と熱媒体外気熱交換器３２とに熱媒体を循環させる熱媒体回路とを備え、第１減圧部８０は、冷媒外気熱交換器８１で冷媒が外気に放熱する状態と、冷媒外気熱交換器８１で冷媒が外気から吸熱する状態とを切り替え可能になっており、冷媒流れ切替部１６は、空気冷却用熱交換器１４で空気が冷却され且つ空気加熱部１２、２２で空気が加熱されている場合、低圧側冷媒熱媒体熱交換器１７に冷媒が流れる状態にする。【選択図】図１
