Abstract

The invention discloses a prompting method and device for a condition of a filter screen. The method comprises the steps that a rotational speed of an inner fan is acquired, and actual wind pressure of an air inlet passage is acquired; ideal wind pressure corresponding to the rotational speed of the inner fan is acquired; if the actual wind pressure of the air inlet passage is lower than the idealwind pressure, prompting information is output, wherein the prompting information is used for prompting an user of filth blockage conditions of the filter screen. According to the prompting method and device for the condition of the filter screen, the problem that the user cannot grasp the filth blockage conditions of the filter screen in real time in the correlation technique is solved.

Description

Technical field [0001] This application relates to the field of air conditioning, and in particular to a method and device for prompting the status of a filter. Background technique [0002] With the continuous improvement of people's living standards, the continuous improvement of living conditions and the warming of global temperature, air conditioning has gradually become a necessity in people's lives. In order to purify the indoor air and ensure the cooling effect, the existing air conditioner is provided with a filter at the return air outlet of the indoor unit to prevent dust or dirt from adhering to the indoor unit evaporator to affect the cooling and heating effect. However, after long-term use, there will be a lot of dust and dirt on the filter, which will reduce the circulating air volume through the heat exchanger, greatly reduce the cooling and heating effect of the air conditioner, and affect the indoor air quality, but the user cannot grasp the filter in real time ...
