Self-adaptive control method and control device for air-conditioner and air-conditioner

Abstract

The invention provides a self-adaptive control method and control device for an air-conditioner and an air-conditioner. The control method comprises the steps that air return parameters and exhaustingparameters of the air-conditioner are obtained; whether the air return parameters and the exhausting parameters meet the first preset condition or not is judged; and if the air return parameters andthe exhausting parameters meet the first preset condition, the opening degree of an electronic expansion valve is adjusted. According to the method, at the air-conditioner system matching stage, the opening degree of the electronic expansion valve can be adjusted according to the air return parameters and the exhausting parameters, self-adaptation of an air-conditioner refrigerating system is achieved, the situation that the opening degree of the electronic expansion valve needs to be adjusted manually for matching the air-conditioner system is avoided, the operation efficiency is high, and the situation that due to frequent adjusting of the opening degree of the electronic expansion valve, refrigerant is leaked can be avoided.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to an adaptive control method for an air conditioner, a control device and an air conditioner. Background technique [0002] At present, when the air conditioner is in the system matching stage, the operator generally selects a similar throttling device based on the reference model or experience, and then performs matching and adjustment according to the actual system operating parameters; using this matching method, the throttling device is often inappropriate In some cases, because the system cannot automatically adjust the parameters of the throttling device to make the throttling device match the model, it is necessary to manually adjust the parameters of the throttling device. Repeatedly, not only the operation efficiency is low, but also the manual adjustment is frequent and easy to exist. Refrigerant leakage poses a safety risk. Contents of the invention ...

AI Technical Summary

Problems solved by technology

[0003] The problem that the present invention solves is that the throttling device selected by the air conditioner in the system matching stage is not suitable, because it cannot automatically adjust the parameters of the throttling device, so that the throttling device is matched with the model, it is necessary to manually adjust the parameters of the throttling device Adjustment, not only the operation efficiency is low, but also frequent manual adjustment is likely to cause refrigerant leakage and cause safety risks
