トポンプ式空気調和機。The compressor, four-way valve, outdoor heat exchanger, parallel circuit of heating expansion valve and check valve, parallel circuit of cooling expansion valve and check valve, and indoor heat exchanger are sequentially connected via refrigerant pipes. In a heat pump air conditioner that is connected to form a refrigeration cycle, both check valves are formed by needle valves that can move up and down depending on the refrigerant pressure and their own weight, and are installed vertically with the outlet side facing upward. A heat pump type air conditioner characterized in that the liquid pipe part of the refrigerant pipe connected to the side is bent in an inverted U shape.
