Claims

[Scope of utility model registration request]

A compressor, a four-way valve, an outdoor heat exchanger, a first on-off valve that is closed during cooling and dehumidification operations, a pressure reducing element for high-load heating, and an evaporator during cooling operations and a heater during dehumidification and heating operations. The auxiliary indoor heat exchanger, the dehumidifying pressure reducing element, and the second opening/closing valve, which are opened during cooling and heating operations, respectively act.
The parallel circuit is connected in an annular manner to a main indoor heat exchanger that functions as an evaporator during cooling and dehumidifying operation and as a heater during heating operation, and branches off from the middle of the external heat exchanger to connect to the first on-off valve. A second parallel circuit including a pressure reducing element for cooling and a third on-off valve that opens during low-load heating and dehumidification operation is connected to a bypass pipe that has a pressure-reducing element for high-load heating as a side path, and a pressure-reducing element for low-load heating. An air conditioner characterized in that a fourth on-off valve that is opened during cooling and dehumidification operation and a third parallel circuit are connected in series.
