An outdoor unit of an air conditioner generally includes an outdoor heat exchanger. An air conditioner indoor unit generally includes an indoor heat exchanger, a throttle device, and a compressor. When the air conditioner performs refrigeration work, the compressor compresses a gaseous refrigerant into a high-temperature high-pressure gaseous state, and sends the gaseous refrigerant to the outdoor heat exchanger for cooling, the high-temperature high-pressure gaseous refrigerant is cooled and then becomes a medium-temperature high-pressure liquid refrigerant, the medium-temperature high-pressure liquid refrigerant is throttled and reduced by the throttling device and becomes a low-temperature low-pressure gas-liquid mixture, and the low-temperature low-pressure gas-liquid mixture absorbs heat in air by the indoor heat exchanger and is vaporized into a gaseous state, so that the refrigeration effect is achieved; the gaseous refrigerant returns to the compressor to continue to be compressed, and the circulation is continued to carry out refrigeration.

The structure, function and implementation process of the air conditioner internal unit are the same as those of the foregoing embodiments, and details are not repeated here.

In addition, the parts of the present embodiment that are not described for the air conditioner may adopt the conventional arrangement in the art.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless explicitly specified otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; may be mechanically coupled, may be electrically coupled or may be in communication with each other; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the present invention, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

In the description above, references to the description of the term "one embodiment," "some embodiments," "an example," "a specific example," or "some examples," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the utility model. In this specification, the schematic representations of the terms used above are not necessarily intended to refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
