Method, device and equipment for detecting filth blockage condition of filter screen and air conditioning system

Abstract

The invention relates to the technical field of filter screen filth blockage detection, in particular to a method, device and equipment for detecting filth blockage condition of a filter screen and an air conditioning system, the method comprises the steps of detecting use information of the air conditioning system under a current wind gear, the use information at least comprises two kinds of information of air purification information, motor operation information, filter screen wind resistance information, accumulated operation time and dust holding capacity, if at least two kinds of information in the use information are not matched with the preset standard information, it shows that filth blockage of the filter screen occurs, and filth blockage reminding information is generated. According to the technical scheme, the filth blockage condition of the filter screen is analyzed in multiple aspects by detecting the information such as the air purification information, the motor operation information, the filter screen wind resistance information, the accumulative operation time and the dust holding capacity, the filth blockage condition of the filter screen can be judged more accurately, a user is reminded to clean the filter screen in time, the situation that the fresh air volume is reduced due to filth blockage is avoided, and the fresh air purification effect is influenced.

Description

technical field [0001] The invention relates to the technical field of detection of dirty and clogged filters, in particular to a detection method, device, equipment and air conditioning system for dirty and clogged filters. Background technique [0002] At present, air-conditioning systems are equipped with filter screens for filtering impurities such as dust and fibers entering the air-conditioning system. However, after the air conditioning system has been running for a long time, the filter is prone to dust accumulation, which may even cause the filter to be clogged, affecting the use effect of the air conditioning system. Especially the fresh air air conditioning system, the fresh air air conditioning system needs to introduce outdoor air into the room, the outdoor air has a higher dust content, and the filter screen of the fresh air air conditioning system is more likely to be dirty and clogged. In order to ensure the normal use of the air conditioning system, the use...
