AIR CONDITIONER

To provide an air conditioner capable of being operated to maintain comfortable temperature by continuing cooling operation.SOLUTION: An air conditioner includes a refrigeration cycle configured by connecting a compressor, a four-way valve, an indoor heat exchanger, an expansion valve and an outdoor heat exchanger so that a refrigerant flows in an order of the compressor, the four-way valve, the indoor heat exchanger, the outdoor heat exchanger and the four-way valve in a heating operation, room temperature detection means detecting a room temperature and target temperature setting means setting a target temperature, and controls air condition so that the room temperature becomes a target temperature. Between a suction pipe of the compressor and the four-way valve, a refrigerant flow passage switching device, a bypass circuit connected to a suction port of the compressor from the flow passage switching device, and a pressure reducing part are further provided. When such a condition that the room temperature becomes lower than the target temperature continues for a predetermined period of time, the flow passage switching device is operated to switch a flow passage.SELECTED DRAWING: Figure 3 【課題】冷房運転を継続させることによって、快適な温度を維持する運転を行うことができる空気調和機を提供することを目的としている。【解決手段】冷房運転時に、圧縮機、四方弁、室外熱交換器、膨張弁、室内熱交換器、前記四方弁の順に冷媒が流れるように接続した冷凍サイクルと、室内温度を検出する室内温度検出手段と、目標温度を設定する目標温度設定手段とを備え、室内温度が目標温度となるように空調制御を行う空気調和機であって、前記圧縮機の吸入管と前記四方弁の間に、冷媒の流路切り替え装置と、前記流路切り替え装置から前記圧縮機の吸入口へ接続するバイパス回路と、減圧部とをさらに備え、室内温度が目標温度を下回った状態を所定の時間継続すると、前記流路切り替え装置を動作し、流路を切り替えることとした。【選択図】図３
