The invention relates to the technical field of air conditioners, and discloses a method for controlling an electronic expansion valve of an air conditioner. The method comprises the steps that the exhaust temperature of the air conditioner within a first preset time period after the air conditioner is started is obtained; the exhaust temperature is compared with a preset temperature threshold value; an air conditioner working condition is determined according to a comparison result; and the electronic expansion valve of the air conditioner is controlled according to the working condition of the air conditioner. The working condition of the air conditioner is obtained according to the exhaust temperature of the air conditioner, the electronic expansion valve of the air conditioner is controlled according to the working condition of the air conditioner, and therefore adjustment of the electronic expansion valve can adapt to different working conditions of the air conditioner, and the working state of a compressor of the air conditioner is better matched with the different working conditions of the air conditioner. The invention further discloses a device for controlling the electronic expansion valve of the air conditioner and the air conditioner.
Description
technical field [0001] The present application relates to the technical field of air conditioning, for example, to a method and device for controlling an electronic expansion valve of an air conditioner, and an air conditioner. Background technique [0002] At present, the working frequency of the inverter air conditioner compressor is constantly changing according to the indoor and outdoor ambient temperature. After the working frequency of the air conditioner compressor changes, the cooling capacity flowing through the pipeline also changes, which must be adjusted through the electronic expansion valve. To adapt to the changing working state of the air conditioner compressor, to realize the frequency conversion control of the air conditioner operation. [0003] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in related technologies: [0004] The existing technology follows a fixed control mec...
