Summary: | The invention discloses a fresh air ventilator filter screen life detection method. The fresh air ventilator filter screen life detection method comprises the following steps that particulate matter concentration N1 indoors in a fixed operation time T is detected by a particulate matter sensor S1 arranged in an indoor environment; a particulate matter sensor S2 arranged behind a fresh air ventilator filter screen detects particulate matter concentration N2 filtered by the filter screen in the fixed operation time T; particulate matter concentration N3 in outdoor air is obtained from a cloud terminal through a network module of a fresh air ventilator; combined air volume Q of the ventilator with the fixed operation time T, the particulate matter mass M actually adsorbed by the filter screenis calculated on the basis of the particulate matter concentration N1, N2 and N3; and combined with the dust holding capacity D of the filter screen, a remaining service life ratio L of the filter screen is calculated on the |
