Control method of electronic expansion valve used for air conditioner and air conditioner

Abstract

The invention relates to the technical field of air conditioners, and particularly provides a control method of an electronic expansion valve used for an air conditioner and the air conditioner. The control method and the air conditioner aim to solve the problem that the reliability of existing air conditioner electronic expansion valves is poor. For the aim, the control method of the electronic expansion valve comprises the following steps that the shutdown time of a compressor is acquired; and whether reset operation of the electronic expansion valve is executed or not is judged according tothe shutdown time. The air conditioner comprises the compressor and a control mechanism, and the control mechanism is used for executing the control method of the electronic expansion valve. Whetherreset operation of the electronic expansion valve is executed or not is judged according to the shutdown time of the compressor, the situation that reset operation is executed every time the compressor is started is avoided, the number of times of executing reset operation is reduced, and therefore the situation that gears or other components in the electronic expansion valve form excessive fit isavoided, the reliability of the electronic expansion valve is improved, the service life of the electronic expansion valve is prolonged, and then the use experience of users is improved.

Description

technical field [0001] The invention relates to the technical field of expansion valves, and specifically provides an electronic expansion valve control method for an air conditioner and an air conditioner. Background technique [0002] Air conditioning refers to the process of regulating and controlling the ambient air in a building or structure by artificial means. During the operation of the air conditioner, the electronic expansion valve is used to control the flow of the refrigerant pipeline to adjust the indoor temperature, so as to meet the user's comfort requirements. However, due to the difference between the preset step threshold and the actual step number of the electronic expansion valve, for example, the preset step threshold is 500 steps, and the actual step number is 510 or 490 steps. With the repeated adjustment of the electronic expansion valve, the accumulated The step deviation is getting bigger and bigger, which will lead to out-of-step phenomenon, which...
