Therefore, by adjusting one or more of the rotation speed of the fan, the opening of the electronic expansion valve and the operation frequency of the compressor corresponding to the condensing side heat exchanger of the air conditioner, more accurate refrigerant leakage control of the air conditioner can be realized according to different refrigerant leakage amounts.
Optionally, adjusting an operating parameter of at least one operating component in the air conditioner according to the refrigerant leakage amount includes: and under the condition that the leakage amount of the refrigerant is in a preset third range, adjusting one or more of the rotating speed of a corresponding fan of a condensing side heat exchanger of the air conditioner, the opening degree of an electronic expansion valve and the operating frequency of a compressor.

The first increment value is 10%. Optionally, the first threshold is 40%.
In some embodiments, the current refrigerant leakage amount of the air conditioner is 60%, that is, the current refrigerant leakage amount is in a third range, the difference between the refrigerant leakage amount and a preset first threshold value is divided by the first increment value to obtain 2 first increment values, the electronic expansion valve opening adjustment value is determined to be 10, and the electronic expansion valve opening is increased by 10 degrees according to the electronic expansion valve opening adjustment value. Because the electronic expansion valve opening of the air conditioner influences the leakage rate of the refrigerant, the leakage rate of the refrigerant can be reduced by adjusting the electronic expansion valve opening of the air conditioner under the condition that the leakage amount of the refrigerant is in a preset third range, thereby avoiding the failure and shutdown of the air conditioner caused by overlarge leakage amount of the refrigerant.

For example: and triggering the air conditioner to be shut down under the condition that the exhaust temperature of the compressor reaches the exhaust protection temperature value of the compressor. Therefore, under the condition that the exhaust temperature of the compressor continuously rises in a short time due to continuous leakage of refrigerant, the exhaust protection temperature of the compressor is timely adjusted, and when the exhaust temperature of the compressor reaches the exhaust protection temperature value of the compressor, the air conditioner is timely triggered to be turned off, so that the increase of power consumption of the compressor caused by the fact that the exhaust temperature of the compressor exceeds a set value is avoided, the service life of the compressor is shortened, and meanwhile, the safety and reliability of the air conditioner can be improved.
