Problems solved by technology

This control method is simple to operate, but when the difference between the current valve opening and the optimal valve opening is relatively large, it takes a long time to traverse, and the number of times of successive accumulation or successive decrement is large, which cannot meet the target exhaust temperature quickly. needs
[0003] For example, when the electronic expansion valve adjusts the valve at a slow speed, assuming that the minimum opening of the electronic expansion valve is 70pls pulse angle, the maximum opening is 500pls pulse angle, and the current opening is 200pls pulse angle, the actual optimal opening (reaching the target discharge The valve opening at air temperature) is 400pls pulse angle, then it takes time to close the valve at the speed of 1 pulse angle every 30 seconds (400-200)*30=6000 seconds
With the existing control method, the response time of the valve action is too long

Abstract

The embodiment of the invention discloses an electronic expansion valve control method and belongs to the technical field of air-conditioner control. The method comprises the steps that the target exhausting temperature is determined according to the outdoor environment temperature; and according to a difference value of the current exhausting temperature and the target exhausting temperature, thevalve opening degree of an electronic expansion valve is controlled. By the adoption of the embodiment, the traversal time of the valve adjusting process of the electronic expansion valve can be shortened, and the valve opening degree corresponding to the target exhausting temperature can be achieved fast. The embodiment of the invention further discloses an electronic expansion valve control device, an air-conditioner and a computer readable storage medium.

Description

technical field [0001] The invention relates to the technical field of air conditioner control, in particular to an electronic expansion valve control method and control device, an air conditioner, and a computer-readable storage medium. Background technique [0002] For the control of the electronic expansion valve in the low-temperature refrigeration state, the existing control method of the air conditioner adopts the method of increasing or decreasing the fixed opening according to the fixed time when looking for the optimal target exhaust temperature, that is, successively accumulating or successively decreasing Fixed opening. This control method is easy to operate, but when the difference between the current valve opening and the optimal valve opening is relatively large, it takes a long time to traverse, and the number of times of successive accumulation or successive decrement is large, which cannot meet the requirement of quickly reaching the target exhaust gas tempe...
