The utility model relates to a heat pump type air conditioner. Including a compressor, a first heat exchanger, a throttling device, second heat exchanger and four valve, wherein the first interface of the high pressure outlet of the compressor and the four way valve with four valve second interface and the first heat exchanger is communicated with the other end of the throttling device the first heat exchanger is communicated with one end and the other end the second heat exchanger of the throttling device is communicated with the fourth interface at the other end of the second heat exchanger and four way valve is communicated with the low-pressure entrance third interface four valve and compressor is communicated with a heating device is connected between the bypass pipeline between fourth and second the interface between low pressure pipeline entrance third interface and the compressor four way valve the four valve heat exchanger. In the system heating operation of the utility model, the heating bypass device can bypass a part of the refrigerant to ensure that the system does not frosting under the standard heating condition, and improves the running range of the continuous heating of the air conditioner.
