配設したことを特徴とする空気調和機。 In an air conditioner having a heat pump type refrigeration cycle, a first bypass pipe is provided with one end connected between the four-way valve and the usage side heat exchanger and the other end connected between the pressure reducing device and the heat source side heat exchanger, This first bypass pipe is provided with a first on-off valve that guides the refrigerant discharged from the compressor during defrosting operation to the heat source side heat exchanger, and one end is connected to the user side heat exchanger and the pressure reducing device. A second bypass pipe whose other end is connected to the suction side piping of the compressor is provided between the two, and the second bypass pipe is configured to open when the temperature of the user side heat exchanger becomes lower than a set value. An air conditioner characterized in that a second on-off valve is provided for returning the refrigerant that has flowed into the user-side heat exchanger to the compressor.
