Abstract

The invention discloses an air conditioner control method, a control device, an air conditioner and a storage medium. The method includes: acquiring the first temperature corresponding to each component in the current electric control box; When the corresponding first temperatures reach the temperature condition for opening the auxiliary electronic expansion valve, the auxiliary electronic expansion valve is controlled to open at the first target opening degree. Wherein, the auxiliary electronic expansion valve of the air conditioner and the electric control heat exchanger are arranged on the first pipeline, and one end of the first pipeline communicates with the first heat exchanger and the second heat exchanger. When the temperature condition for opening the auxiliary electronic expansion valve is reached, the auxiliary electronic expansion valve is controlled to open the first target opening, so that the refrigerant between the first heat exchanger and the second heat exchanger flows into the electronically controlled heat exchange The device performs evaporation and heat absorption, thereby realizing the cooling control of the components of the electric control box.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner control method, a control device, an air conditioner and a storage medium. Background technique [0002] With the rapid development of multi-connected air conditioners, in order to reduce the cost of the whole machine, without changing the performance requirements, multi-connected air conditioners are more and more inclined to use large-displacement, high-speed compressors to reduce the number of compressors. However, as the displacement of the compressor and the speed of the fan increase, the input current of the compressor drive board also increases accordingly, and the heat generated by the electronic control components on the drive board is greater. When the spontaneous heat dissipation rate of the device is too slow, the electronic control components are easily damaged. [0003] The above content is only used to assist in understanding the technical soluti...
