Claims

[Scope of utility model registration request]

The heat exchange tubes 61, 62 of the outdoor heat exchanger 6, which exchanges heat with outdoor air and serves as an evaporator during heating, are made into two systems, and the heat exchange tubes 61, 62 of these first and second systems are arranged in the ventilation direction. The heat exchange tubes 61 and 62 are arranged in parallel in orthogonal directions, and branch liquid pipes 81 and 82 are connected to the inlet sides of these heat exchange tubes 61 and 62 for each system during heating. A temperature-sensitive expansion valve 51 is installed in the connecting branch liquid pipe 81, and a capillary tube 52 is installed in the branch liquid pipe 82 connected to the heat exchange tube 62 of the second system. A header 91 is connected to the outlet side during heating, and
The temperature sensing tube 51a of the expansion valve 51 was installed in the refrigerant confluence area where the refrigerants merge at the header 91, and the temperature sensing part 10 of the de-icer was installed on the inlet side of the heat exchange tube 62 of the second system during heating. An air-cooled heat pump type air conditioner characterized by:
