[0050] Further, please refer to Figure 4 , Figure 4 In order to propose a fourth embodiment of the air conditioner control method of the present invention based on the second embodiment, the air conditioner control method further includes:
[0051] Step S60, after the air conditioner exits the defrosting mode, acquire the indoor ambient temperature of the air conditioner;
[0052] Step S70, calculating the target operating frequency of the air conditioner compressor according to the indoor ambient temperature, the outdoor ambient temperature, and the current set temperature of the air conditioner.
[0053] In actual use, the user will adjust the set temperature of the air conditioner at any time. After the user adjusts the set temperature of the air conditioner, the air conditioner will adjust the temperature according to the outdoor environment temperature and indoor The temperature and the set temperature recalculate the target operating frequency of the compressor, and ...

The invention discloses an air conditioner control method. After the air conditioner exits the defrosting mode, the operating frequency of the air conditioner compressor and the opening degree of the air conditioner expansion valve are detected in real time. When the current operating frequency of the air conditioner compressor is less than or When it is equal to the preset frequency and the opening degree of the expansion valve of the air conditioner is greater than or equal to the preset opening degree, the enthalpy injection valve of the air conditioner is opened. In addition, the present invention also proposes an air conditioner and a computer-readable storage medium. The embodiment of the present invention proposes a method for controlling an air conditioner. The operating frequency of the compressor of the air conditioner is less than the preset frequency and the opening of the expansion valve of the air conditioner is When the opening is less than the preset opening, the enthalpy injection operation is performed to ensure that the load of the air conditioner is in a relatively low state during the enthalpy injection, so as to prevent the liquid refrigerant from entering the compression chamber of the air conditioner from the enthalpy injection port, resulting in a sudden increase in current The phenomenon of damaging the machine realizes the current protection function of the air conditioner.
Description
technical field [0001] The present invention relates to the field of air conditioners, in particular to an air conditioner control method, an air conditioner system, an air conditioner and a computer-readable storage medium. Background technique [0002] With the enhancement of the society and the government's awareness of environmental protection, the disadvantages of the previous northern boiler central heating are becoming more and more obvious, and an environmentally friendly heating method is urgently needed to replace it. Air source heat pump has also become one of the most important members. Air source heat pump units are prone to frost in low temperature environments, resulting in attenuation of heating capacity, which seriously affects the use of users. At present, in order to solve this problem, the market adopts the frequency conversion air source heat pump technology with the function of increasing enthalpy by air injection (referred to as "enthalpy injection + ...
