Air conditioner control method, storage medium and control device

Abstract

The invention relates to the technical field of air conditioners, and particularly provides an air conditioner control method, a storage medium and a control device. The invention aims to solve the problem that the heat exchange efficiency of a heat exchanger of an outdoor unit is relatively poor due to the problem that the outdoor unit is not cleaned in time or refrigerant leakage is not found in time in the prior art. In order to achieve the purpose, an outdoor unit comprises a heat exchanger, a throttling valve and a pressure detection device arranged at the position, located in front of the throttling valve, of a refrigerant pipeline. The control method comprises the steps of when an air conditioner is in a preset working condition, acquiring the pressure of the position, in front of the throttling valve, of the refrigerant pipeline; comparing the pressure with the first preset pressure and the second preset pressure; and on the basis of the comparison result, selectively sending out prompt information of refrigerant leakage or self-cleaning. According to the air conditioner control method, the storage medium and the control device provided by the invention, the prompt information is selectively sent out according to the pressure detected by the pressure detection device, and a user takes corresponding countermeasures in time according to the prompt information, so that the problems existing in the air conditioner can be solved in time.

Description

technical field [0001] The invention relates to the technical field of air conditioners, and specifically provides an air conditioner control method, storage medium and control device. Background technique [0002] The heat exchanger of the outdoor unit needs to be cleaned regularly. If it is not cleaned for a long time, a large amount of dust will accumulate on the heat exchanger, which will reduce the heat exchange effect. At present, a reminder mark is usually pasted on the panel of the air conditioner to remind the user to start self-cleaning regularly. However, users generally do not or can hardly notice the prompt, so they cannot perform regular self-cleaning. After a long time, the heat exchange efficiency of the heat exchanger will also deteriorate. [0003] In addition, after the outdoor unit of the air conditioner has been running for a long time, the components of the outdoor unit will age, and the refrigerant in the air conditioner may leak and other problems. ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, to solve the problem that the heat exchange efficiency of the heat exchanger of the outdoor unit is poor due to the failure to clean the outdoor unit in time or to discover the leakage of the refrigerant in time, the first aspect of the present invention An air conditioner control method is provided, the air conditioner includes an outdoor unit, the outdoor unit includes a heat exchanger and a throttle valve, the heat exchanger is connected to the throttle valve through a refrigerant pipeline, the The heat exchanger is used to exchange heat between the refrigerant and the outdoor air, the throttle valve is used to adjust the flow of the refrigerant coming out of the heat exchanger, the outdoor unit also includes a pressure detection device, and the pressure detection device is set at The refrigerant pipeline is located in front of the throttle valve, and the control method includes: obtaining operating parameters and environmental parameters of the air conditioner; based on the operating parameters and the environmental parameters, judging whether the air conditioner In the preset working condition; when the air conditioner is in the preset working condition, obtain the pressure of the refrigerant pipeline at the position before the throttle valve; compare the pressure with the first preset pressure and the first preset pressure 2. The size of the preset pressure; based on the comparison result, selectively send out the prompt information of "refrigerant leakage" or "self-cleaning"; wherein, the second preset pressure is greater than the first preset pressure
