[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, which comprises the steps of detecting the operating frequency of a compressor of an air conditioner and the opening of an expansion valve ofthe air conditioner in real time after the air conditioner exits a defrosting mode; and opening an enhanced vapor injection valve of the air conditioner when the current operating frequency of the compressor of the air conditioner is less than or equal to the preset frequency and the opening of the expansion valve of the air conditioner is greater than or equal to the preset opening. In addition,the invention also provides the air conditioner and a computer readable storage medium. According to the air conditioner control method provided by an embodiment of the present invention, when 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 less than the preset opening, enhanced vapor injection operation can be performed, and it is ensured that the load capacity of the air conditioner is in a lower state during enhanced vapor injection, so that the phenomenon that a liquid refrigerant enters a compression cavity of the air conditioner from an enhanced vapor injection port and causes the sudden rise of current to damage the machine is avoided, and the current protection function of the air conditioner is realized.
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 + ...
