Problems solved by technology
However, when the air conditioner is cooling and evaporating, the refrigerant flow rate is small and the fan keeps running at a high speed, which will cause the refrigeration system to be overheated during evaporation. Even if the frequency of the compressor is increased, the cooling capacity will increase slightly, resulting in poor energy efficiency of the refrigeration system and evaporation overheating It will also indirectly lead to an increase in the exhaust temperature of the compressor and reduce the reliability of the system operation.

[0060] refer to figure 2 , the first embodiment of the air-conditioning control method of the present invention is proposed, and the air-conditioning control method includes:
[0061] Step S10, obtaining the operating frequency of the compressor, the inlet temperature of the evaporator and the outlet temperature of the evaporator;
[0062] Specifically, after the air conditioner is powered on or when the temperature set by the user is less than or equal to the preset temperature and the rotation speed is at the highest gear, the current operating mode of the air conditioner is obtained first, and when the operating mode is cooling mode, step S10 is executed.
[0063] The inlet temperature of the evaporator is the temperature value at the inlet of the evaporator; the outlet temperature of the evaporator is the temperature value at the outlet of the evaporator. In addition, the fan speed may also be obtained as a reference value for speed adjustment, and the fan speed may spec...

The invention discloses an air conditioner control method, the method comprising: obtaining the operating frequency of the compressor, the inlet temperature of the evaporator and the outlet temperature of the evaporator; according to the operating frequency of the compressor, the inlet temperature and the outlet temperature, Judging whether the fan speed needs to be reduced; if it is determined that the fan speed needs to be reduced, then reducing the fan speed. The invention also discloses an air conditioner control device, an air conditioner and a readable storage medium. The invention aims to improve the energy efficiency of the refrigeration system and increase the reliability of the system operation.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method, an air conditioner control device, an air conditioner and a readable storage medium. Background technique [0002] With the development of technology, new refrigerants (such as R32 refrigerant) are widely used due to their excellent performance. The injection amount of the new refrigerant is less than that of the traditional refrigerant, and the reduction of the refrigerant charge will lead to a decrease in the overall refrigerant flow rate of the refrigeration system. At the same time, as the heat exchangers of air conditioners become more and more compact, the demand for high-capacity output of refrigeration systems is gradually increasing. In order to achieve high-capacity output of cooling, the air conditioner generally maintains both the indoor fan and the outdoor fan at high speeds, and the fan speed is generally maintained at th...
