Abstract

The invention discloses a method for predicating dynamic changes of indoor PM2.5 concentration and belongs to the technical field of monitoring of particle concentration. The method comprises the following steps: 1 establishing a Simulink dynamic simulation model; 2 detecting indoor particle PM2.5 concentration, outdoor particle PM2.5 concentration, and fresh air volume and air returning volume of an air conditioning system, and calculating a fresh air ratio and an air exchange frequency; 3 inputting obtained parameters into the dynamic simulation model, and obtaining indoor particle PM2.5 concentration changing data according to actual detection data; 4 controlling the change of a certain input parameter in the dynamic simulation model and keeping other parameters unchanged; obtaining indoor particle PM2.5 concentration changing data according to a theoretical set value; and 5 analyzing and comparing the data obtained in the step 3 and the step 4 and formulating an optimal indoor ventilation scheme. The detection scheme has a reasonable design, the detection cost is low and the precision is high; the aim of predicating the change of the indoor particle concentration can be realized and the instantaneity is good.

Description

technical field

[0001] The invention relates to the technical field of indoor particle concentration monitoring, and more specifically, relates to a method for predicting the dynamic change of indoor PM2.5 concentration. Background technique

[0002] With the advancement of my country's industrialization, a large number of harmful substances are discharged into the air, causing outdoor air pollution. Among them, suspended dust particles (PM2.5) with a diameter of less than or equal to 2.5 microns pose a great threat to human health and are easily accumulated in the deep lungs. Outdoor air pollution directly affects the quality of the indoor environment. If we can monitor the concentration of outdoor particulate matter in time, grasp the changing trend of indoor particulate matter concentration, formulate a suitable indoor ventilation plan, and control the indoor particulate matter concentration within a reasonable range, it will have a positive effect on ensuring human healt...
