[0096] Based on the first embodiment, the second embodiment of the control method of the electronic expansion valve of the present invention is proposed, referring to image 3 , in this embodiment, step S300 includes:

[0097] Step S310, calculating the temperature amplitude between the maximum exhaust temperature and the current exhaust temperature each time the current exhaust temperature is acquired;

[0098]Step S320, obtaining the current opening degree of the electronic expansion valve;

[0099] Step S320, adjusting the opening degree of the electronic expansion valve based on the temperature amplitude and the current opening degree.

[0100] In this embodiment, each time the current exhaust temperature is obtained, the temperature amplitude between the maximum exhaust temperature and the current exhaust temperature is calculated, and the current opening degree of the electronic expansion valve is acquired, based on the temperature amplitude value and the current openi...

Abstract

The present application discloses an electronic expansion valve control method, comprising: when an air conditioner is in a heating mode, and maintains the duration of the heating mode to reach a first preset time period, acquiring a maximum exhaust temperature of a compressor of the air conditioner in the first preset time period; acquiring a current exhaust temperature of the compressor every second preset time period; when acquiring the current exhaust temperature each time, adjusting the opening degree of the electronic expansion valve corresponding to the air conditioner according to the maximum exhaust temperature and the current exhaust temperature. The present application further discloses an air conditioner and a computer readable storage medium.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a control method for an electronic expansion valve, an air conditioner and a computer-readable storage medium. Background technique [0002] At present, when the air conditioner is running in a low-temperature environment, the outdoor chance of the air conditioner will be frosted, so that the operation state of the air conditioner is in an unsteady state. If the opening of the electronic expansion valve of the air conditioner is fixed at the set opening, the discharge temperature of the compressor will drop rapidly as time goes by, resulting in a decrease in the outlet air temperature of the air conditioner, making the heating performance of the air conditioner unstable. In turn, it affects the thermal comfort of the room and causes troubles for users. [0003] The above content is only used to assist in understanding the technical solution of the present invent...
