[0027] The terms "first", "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0028] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0030] Reference Figure 1 , Figure 2 The heat pump air conditioner according to the embodiment of the present application includes: an outdoor unit 10, which can be installed in an outdoor space and is used to perform heat exchange between a refrigerant and outdoor air.

[0031] The outdoor unit 10 may be provided with components such as a compressor 11, a four-way valve 13, an outdoor heat exchanger 14, a throttling device 15 and a water-fluorine heat exchanger 12, and these components are connected to form an outdoor refrigerant circuit by piping.

[0032] The water-fluorine heat exchanger 12 includes a fluorine path side and a water path side. Refrigerant flows through the fluorine path side, and water flows through the water path side. The refrigerant and water exchange heat at the water-fluorine heat exchanger 12 .

[0033] The fluorine circuit side is connected to the outdoor refrigerant circuit, and the water circuit side has a water outlet end and a water return end.

[0034] In the outdoor refrigerant circuit, the output end of the compressor 11 is connected to the d tube of the four-way valve 13, the e tube and the c tube of the four-way valve 13 are respectively connected to the fluorine path side of the outdoor heat exchanger 14 and the water-fluorine heat exchanger 12, and the s tube of the four-way valve 13 is connected to the input end of the compressor 11.

[0035] The compressor 11 sucks in and compresses the refrigerant to make it a high-temperature and high-pressure state. The four-way valve 13 is used to selectively allow the refrigerant from the compressor 11 to flow to the outdoor heat exchanger 14 or to the water-fluorine heat exchanger 12. The outdoor heat exchanger 14 is used to perform heat exchange between outdoor air and the refrigerant. The throttling device 15 is used to reduce the pressure of the refrigerant. The water-fluorine heat exchanger 12 is used to perform heat exchange between water and the refrigerant.

[0036] For example, during heating operation, the compressor 11 of the outdoor unit 10 compresses the refrigerant, and the refrigerant compressed to high temperature and high pressure continues to flow through the four-way valve 13 to the fluorine path side of the water-fluorine heat exchanger 12. The water in the water path side of the water-fluorine heat exchanger 12 absorbs the heat of the refrigerant and is heated, and at the same time, the refrigerant in the water-fluorine heat exchanger 12 absorbs the heat and is condensed.

[0037] The refrigerant at the water-fluorine heat exchanger 12 continues to flow to the throttling device 15, which reduces the pressure and temperature of the refrigerant. The outdoor heat exchanger 14 evaporates the refrigerant into a gaseous state. The gaseous refrigerant continues to flow to the compressor 11.
