Air-conditioning air volume self-compensation control method, control system and air-conditioning

Abstract

The invention relates to the field of household appliance control, in particular to a self-compensation control method and system for the air volume of an air conditioner, and the air conditioner. The method comprises the following steps: acquiring the current filth blockage degree of a dust filtering screen of the air conditioner; acquiring the corresponding compensation for the rotating speed of a draught fan according to the current filth blockage degree; acquiring the target rotating speed of the draught fan according to the compensation for the rotating speed of the draught fan; and controlling the running of the draught fan according to the target rotating speed of the draught fan. According to the method provided by the invention, the filth blockage degree of the dust filtering screen of the air conditioner is detected, and the corresponding compensation is made for the rotating speed of the draught fan, so that the air volume of the air conditioner can be prevented from being lower than that outputted before filth blockage, and the air volume required by the system can still be outputted by the air conditioner in a dust-cumulated manner. Accordingly, not only are the refrigerating and heating effects of the air conditioner as well as the use comfort of a user improved, but also the energy-saving and environment-friendly properties are further achieved.

Description

technical field [0001] The invention relates to the field of home appliance control, in particular to an air volume self-compensation control method for an air conditioner, a control system and an air conditioner. Background technique [0002] The cooling and heating capacity is one of the most important indicators of the air conditioner, and the air supply volume of the air conditioner is one of the important factors affecting the cooling and heating capacity. If the cooling or heating temperature of the evaporator is already very low or high, but the air circulation through the evaporator is not enough to take away the heat in time, not only the capacity of the air conditioner will be reduced, but the cooling and heating effects will also deteriorate, and the user experience will deteriorate. If it is worse, it will cause damage to the air conditioner or trigger the protection mechanism to stop running. [0003] The air supply volume of the air conditioner is directly pro...

AI Technical Summary

Problems solved by technology

In this case, the air supply volume provided by the same fan speed will be greatly reduced, which cannot meet the needs of the system, so that the air conditioner will not operate in the best state, and the energy consumption of the system will also increase.

Even if the user cleans the dust filter at intervals, the same problem will exist in the process before cleaning
