The invention relates to the technical field of intelligent air conditioners, and discloses a method for adjusting an electronic expansion valve of an air conditioner outdoor unit, the electronic expansion valve is arranged at a main outlet of a condenser, and the method comprises the steps that the actual exhaust temperature of a compressor is detected; under the condition that the absolute valueof the difference value between the actual exhaust temperature and the target exhaust temperature of the compressor belongs to the first interval, the temperature changing time of the exhaust temperature of the compressor is detected; the temperature changing time is the time used for changing the exhaust temperature from the current temperature to the adjacent temperature; the valve adjusting speed is determined according to the temperature changing time; and the electronic expansion valve is adjusted according to the valve adjusting speed. The electronic expansion valve can be prevented from being adjusted too fast or too slow, the opening degree of the electronic expansion valve can be adjusted more stably, and large exhaust and power fluctuation of the compressor is avoided. The invention further discloses a device for adjusting the electronic expansion valve of the air conditioner outdoor unit and the air conditioner outdoor unit.
Description
technical field [0001] The present application relates to the technical field of intelligent air conditioners, for example, to a method and device for adjusting an electronic expansion valve of an outdoor unit of an air conditioner, and an outdoor unit of an air conditioner. Background technique [0002] At present, an electronic expansion valve is installed at the general outlet of the condenser of the outdoor unit of the air conditioner, and the flow rate of the refrigerant can be adjusted by adjusting the opening of the electronic expansion valve. The electronic expansion valve uses the electrical signal generated by the adjusted parameters to control the voltage or current applied to the expansion valve, thereby achieving the purpose of adjusting the liquid supply. In the actual application process, after the target opening of the electronic expansion valve is determined, it is usually necessary to adjust the opening of the expansion valve to the target opening according...
