A kind of air-conditioning air volume self-compensation control method, control system and air conditioner

Abstract

The invention relates to the field of household appliance control, in particular to an air conditioner air volume self-compensation control method, a control system and an air conditioner. The method comprises the following steps: the current filth blockage degree of an air conditioner dust filter gauze is obtained; according to the pre-built draught fan rotating speed compensation amount calculation formula, the draught fan rotating speed compensation amount corresponding to the current filth blockage degree is obtained; according to the draught fan rotating speed compensation amount, the target rotating speed of a draught fan is obtained; and according to the target rotating speed of the draught fan, the draught fan is controlled to run. Through detection of the filth blockage degree of the air conditioner dust filter gauze, compensation for the wind speed of the draught fan is correspondingly carried out according to the filth blockage degree, and therefore the air outlet volume of the air conditioner cannot be reduced compared with the volume of the air conditioner before filth blockage, it is ensured that the air conditioner can still output the air volume needed by the system under the dust accumulation state, the refrigeration and heating effect of the air conditioner are improved, the use comfort of a user is improved, more energy is saved, and the environment friendliness is better 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
