Problems solved by technology
When the air conditioner is turned on again, liquid refrigerant will flow through the four-way valve of the air conditioner. If the four-way valve performs a reversing operation at this time, the slider of the four-way valve will collide with the liquid refrigerant, causing the four-way valve to It is easy to be damaged due to the impact of liquid refrigerant, causing problems such as heat exchange failure of the air conditioner
Therefore, the reliability of traditional air conditioners is low during operation

Embodiment Construction
[0047] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0048] An embodiment of the present invention provides a method for controlling an outdoor unit of an air conditioner, such as figure 1 As shown, the air conditioner outdoor unit includes a fan 110, a compressor 120 and a four-way valve 130, as figure 2 As shown, the control method provided by the embodiment of the present invention includes the following steps:
[0049] S100, control fan 110 and compressor 120 to start, and record the start time t 1 ;
[0050] The starting sequence of the fan 110 and the compressor 120 can be flexibly selected, for example, the compressor 120 is started first, and then the fan 110 is started, and the recorded startup time t 1 It may be the start-up time of the fan 110 or the start-up time of the compressor 1...

The invention discloses a method for controlling an outdoor unit of an air conditioner. The outdoor unit of an air conditioner includes a fan, a compressor and a four-way valve, comprising the following steps: controlling the startup of the fan and the compressor, and recording the startup time; judging the Whether the startup duration is longer than the first preset time interval; when the startup duration is longer than the first preset time interval, the four-way valve is controlled to perform reversing. After adopting this control method, even if there is liquid refrigerant before the outdoor unit of the air conditioner starts, after the fan and compressor run for the first preset time interval, this part of the liquid refrigerant has already turned into gas in the heat exchange cycle, and then the four-way valve It is not easy to be subjected to hydraulic impact when changing directions, so this control method can improve the reliability of the outdoor unit of the air conditioner during operation. The invention also discloses a control device of the outdoor machine of the air conditioner and the outdoor machine of the air conditioner.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for controlling an outdoor unit of an air conditioner. The invention also relates to a control device of an air conditioner outdoor unit and an air conditioner outdoor unit. Background technique [0002] The air conditioner is turned off after running for a period of time. After the shut down air conditioner is left standing for a period of time under the condition of low ambient temperature, due to the influence of factors such as refrigerant migration and pressure difference balance, the refrigerant will exist outdoors in a liquid state. In the pipeline and heat exchanger of the machine. When the air conditioner is turned on again, liquid refrigerant will flow through the four-way valve of the air conditioner. If the four-way valve performs a reversing operation at this time, the slider of the four-way valve will collide with the liquid refrigerant, causing t...
