In the embodiment of the present disclosure, the air conditioning equipment may increase the opening degree of the electronic expansion valve to the maximum opening degree, or increase the opening degree of the electronic expansion valve according to a preset electronic expansion valve opening degree correspondence relationship.
In practical application, the outdoor environment temperature and the air conditioner exhaust temperature meet the temperature control condition, and it can be understood that the outdoor environment temperature reaches the set outdoor environment temperature threshold, and the air conditioner exhaust temperature reaches the set exhaust temperature threshold.
Optionally, the temperature control conditions are:

And S04, adjusting the electronic expansion valve and/or increasing the frequency of the compressor according to the corresponding relation between the indoor environment temperature, the temperature set by the user, the opening degree of the electronic expansion valve and the frequency of the compressor.
In the embodiment of the present disclosure, the opening degree of the electronic expansion valve is adjusted individually according to the corresponding relationship between the indoor environment temperature, the user-set temperature, and the opening degree of the electronic expansion valve. The adjustment of the opening of the electronic expansion valve can be to increase the opening of the electronic expansion valve or to decrease the opening of the electronic expansion valve. By increasing the opening, the air conditioner exhaust temperature is decreased. By reducing the opening, the overall refrigerating capacity of the air conditioner is prevented from being reduced.
In the embodiment of the disclosure, the independent increase of the compressor frequency can be realized by increasing the flow of air conditioning refrigerants through frequency increase according to the corresponding relation between the indoor environment temperature, the user set temperature and the compressor frequency increase value, so that the heat exchange of the air conditioning equipment is faster, and the user set temperature can be quickly reached with better heat exchange efficiency.
