Embodiment 1

[0026] Based on the above inventive concepts, embodiments of the present invention provide an air conditioner, such as image 3 As shown, the air conditioner 20 includes: a four-way valve 201, a compressor 202, an indoor heat exchanger 103, an outdoor heat exchanger 104, and an electronic expansion valve 105;

[0027] The first end D of the four-way valve 201 is connected to the exhaust pipe of the compressor 202, the second end C of the four-way valve 201 is connected to the indoor heat exchanger 203, and the third end S of the four-way valve 201 is connected to the suction of the compressor 202. The fourth end E of the tube and the four-way valve 201 is connected to the outdoor heat exchanger 204, and the indoor heat exchanger 203 is connected to the outdoor heat exchanger 204 through the electronic expansion valve 205; The end D communicates with the second end C and connects the third end S with the fourth end E; when the four-way valve is in the energized state, it commun...

Embodiment 2

[0030] Based on the air conditioner provided by the first embodiment of the present invention, considering that figure 2 When the air conditioner in the prior art shown is running in the heating mode, the pilot slide valve 2 will remain on the left side by default due to the elastic force of the spring 3 when the four-way valve is not energized. After the air conditioner heating mode is started, the four-way valve will be energized to move the pilot slide valve 2 to the right, thereby causing a pressure difference between the piston chamber 4 and the piston chamber 5, and finally causing the main slide valve 6 to move to the right, and then To realize the heating cycle. That is, in the air conditioner of the prior art, when the four-way valve is first energized, the refrigerant system will maintain a refrigeration cycle for a period of time before starting a heating cycle. In the air conditioner provided in the first embodiment above, the four-way valve can connect the exhau...

Embodiment 3

[0054] An embodiment of the present invention provides an air conditioner control device, which is applied to the air conditioner provided in the first embodiment above. In the embodiment of the present invention, functional modules can be divided according to the method example in the second embodiment above. For example, each functional module can be divided corresponding to each function, or two or more functions can be integrated into one processing module. . The above-mentioned integrated modules can be implemented in the form of hardware or in the form of software function modules. It should be noted that the division of modules in the embodiment of the present invention is schematic, and is only a logical function division, and there may be another division manner in actual implementation. In the case of dividing each functional module corresponding to each function, such as Figure 6 A schematic diagram of a possible structure of the control device for the air condit...

Abstract

The embodiment of the invention provides an air conditioner and a control method and device thereof, and relates to the technical field of air conditioners. The embodiment can solve the problem that afour-way valve needs to be powered on continuously in the heating process. The air conditioner comprises a compressor, the four-way valve, an indoor heat exchanger, an outdoor heat exchanger and an electronic expansion valve; the first end of the four-way valve is connected with an exhaust pipe of the compressor, the second end of the four-way valve is connected with the indoor heat exchanger, the third end of the four-way valve is connected with an air sucking pipe of the compressor, the fourth end of the four-way valve is connected with the outdoor heat exchanger, and the indoor heat exchanger is connected with the outdoor heat exchanger through the electronic expansion valve; in the state that the four-way valve is powered off, the first end and the second end are communicated, and thethird end and the fourth end are communicated; and in the state that the four-way valve is powered on, the first end and the fourth end are communicated, and the second end and the third end are communicated. The control method and device are applied to the air conditioner.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner and its control method and device. Background technique [0002] At present, the air conditioners on the market require the four-way valve to be in the energized state for a long time during the heating process. Considering that the application of air conditioners is becoming more and more extensive, some scenarios require During the process, the four-way valve needs to be continuously energized, which will not only increase energy consumption, but also affect the service life of components. Contents of the invention [0003] The invention provides an air conditioner and its control method and device, which can solve the problem that the four-way valve needs to be continuously energized during the heating process. [0004] In order to achieve the above object, embodiments of the present invention adopt the following technical solutions: [...
