The value range of the preset indoor set temperature is usually 20-30 ℃, the set temperature at the indoor side has little influence on the opening degree of the electronic expansion valve, and the preferred value of the preset indoor set temperature can be 26 ℃.
In one possible embodiment, a first opening range of the electronic expansion valve at which a target air conditioning operation load is satisfied is determined based on the outdoor ambient temperature; the upper limit value of the first opening degree range is set as a first target opening degree.
The method comprises the steps of inquiring the opening range of an electronic expansion valve when the air conditioner is in a stable operation state under the same working condition as the current outdoor environment temperature from historical operation data of the target air conditioner, and recording the opening range as a first opening range, or carrying out simulation experiments on the target air conditioner based on the current outdoor environment temperature, placing the electronic expansion valve in different opening ranges, and taking the opening range when the target air conditioner is in the stable operation state (namely, the problems of poor liquid return and the like do not occur) as the first opening range.
When the electronic expansion valve is in the first opening range, the target air conditioner can be in a stable operation state, the problems of poor liquid return and the like are avoided, the exhaust temperature is higher when the opening of the electronic expansion valve is smaller, the maximum value of the first opening range is taken as the first target opening in order to guarantee the air conditioner operation load and take the exhaust temperature into consideration, and the exhaust high-temperature protection is avoided while the air conditioner comfort is improved.
Step (2): a second target opening degree at which the compressor discharge temperature of the target air conditioner is lower than a preset maximum discharge temperature is determined based on the outdoor ambient temperature.
In order to enable the target air conditioner to stably operate, the preset maximum discharge temperature may be in a proportional relationship with the outdoor ambient temperature, i.e., the preset maximum discharge temperature is smaller as the outdoor ambient temperature is lower, so that the compressor reaches a stable operation state.

when T is6≥TOuter ring≥T7When, T7Value of [ 10-15%]The preset maximum exhaust temperature can be 90 ℃;
when T is7＞TOuter ring＞T8When, T8Value of [0 to 7%]The preset maximum exhaust temperature can be 85 ℃;
when T is8≥TOuter ring≥T9When, T9The value is [ -15 to-10 [)]And the preset maximum exhaust temperature may be 75 ℃.
In one possible embodiment, a second opening range in which the compressor discharge temperature of the target air conditioner is lower than a preset maximum discharge temperature is determined based on the outdoor ambient temperature; the lower limit value of the second opening degree range is set as the second target opening degree.
And inquiring the opening range of the electronic expansion valve when the exhaust temperature is lower than the preset highest exhaust temperature under the working condition that the exhaust temperature is the same as the current outdoor environment temperature from historical operation data of the target air conditioner, and recording the opening range as a second opening range, or performing a simulation experiment on the target air conditioner based on the current outdoor environment temperature, placing the electronic expansion valve in different opening ranges, and taking the opening range when the exhaust temperature is lower than the preset highest exhaust temperature as the second opening range.
When the electronic expansion valve is in the second opening range, the exhaust temperature of the target air conditioner meets the condition that the maximum exhaust temperature of the compressor is lower than the preset maximum exhaust temperature, and the lower opening of the electronic expansion valve is considered to be better, so that the problem of poor liquid return can be avoided.
And (3): the maximum value of the first target opening degree and the second target opening degree is taken as an initial opening degree.
In the air of the targetWhen the air conditioner is started in a refrigeration mode or a dehumidification mode, if T isOuter ring≥T4The maximum value of the first target opening degree and the second target opening degree is set as an initial opening degree. If T is the target air conditioner started in the heating modeOuter ring≥T9The maximum value of the first target opening degree and the second target opening degree is set as an initial opening degree.
When the opening degree of the electronic expansion valve is smaller, the air conditioner is easier to perform exhaust high-temperature protection, the maximum value of the first target opening degree and the second target opening degree is used as the initial opening degree, exhaust high-temperature protection caused by overhigh exhaust temperature can be preferentially avoided, the service life of the compressor is prolonged, and the reliability of the compressor is improved while the comfort stability of the target air conditioner is considered.
In a specific embodiment, the method further includes: when T is4＞TOuter ring≥T5When the air conditioner is started, the first target opening degree is the upper limit value of the valve step of the starting low-temperature refrigeration oil return liquid return test under the working condition, and the minimum value of the first target opening degree and the second target opening degree is used as the initial opening degree so as to preferentially ensure the starting reliability of the air conditioner.
