Abstract

The invention relates to a filtering screen service life forecasting method based on the dust holding capacity. The method comprises the following steps of (1) obtaining an attribute parameter of a filter screen or an air purification device; (2) calculating the air-out quantity Q of the air purification device; (3) determining the concentration P of particulate matters in the air; (4) calculatingthe weight delta sigma[i] of the particulate matters filtered by the filtering screen in a unit time delta[t] according to a calculation formula that deltasigm[i] equals to PQ[Eta][i]delta[t]. (5) calculating the accumulated dust collecting quantity sigma[i]: accumulating the weight delta sigma[i]of the particulate matters filtered by the filtering screen in a unit time delta[t] onto the originalaccumulated dust collection quantity to obtain the updated accumulated dust collection quantity sigma[i]; (6) comparing the updated accumulated dust collecting quantity and the designed dust accommodating quantity sigma [0,i]; judging whether the filtering screen needs to be replaced or not. The filtering screen service life forecasting method based on the dust holding capacity can be used for more accurately predicting the filtering screen service life so as to remind people of timely replacing the filtering screen of an air purifier or a fresh air system.

Description

technical field [0001] The invention relates to a method for predicting the life of consumables, in particular to a method for predicting the life of a filter screen based on dust holding capacity, and also to an air purification device capable of predicting the life of the filter screen. Background technique [0002] With the development of society, people's health awareness is gradually improving. Air quality is one of the key points that people pay attention to nowadays, especially indoor air quality. In order to reduce the impact of particulate matter (PM2.5) in the air on the human body, more and more families are beginning to use air purifiers or fresh air systems. [0003] Both the air purifier and the fresh air system filter the air through the filter, and discharge the filtered air into the room to improve the indoor air quality. The difference is that the air purifier sucks in air from the room, and then discharges it into the room after being filtered. The fres...
