ヒートポンプ空気調和機。 Multiple indoor units are installed in parallel to one outdoor unit, and an on-off valve is installed on each of the gas side piping and liquid side piping during heating of each indoor unit, creating a heat pump refrigerant circuit. A liquid drain circuit is installed between the indoor heat exchanger and the on-off valve in the piping, and is connected to the downstream piping of the pressure reducing device of the outdoor unit, which has low pressure during heating, through a check valve that communicates with the pressure reducing device only during heating. Switchable heat pump air conditioner installed.
