Abstract
The frequent occurrence of haze, does not only pollute the indoor air quality seriously, but also endanger human health. University library is one of the most high frequency and close contact college environment for students, so it should keep good indoor air quality. But with the arrival of the northern heating period, outdoor airborne particulate matter concentration would increase and permeate the room through the windows and doors gap. With the frequently movement of people, it suspends in the air for a long time, seriously affects environmental quality of the reading room. In this paper, the diffusion mechanism of outdoor PM2.5 into the indoor is studied under different levels of haze pollution of a university library in north. Through the use of aerosol detector and other related equipment on the indoor and outdoor fine particulate PM2.5 pollutant concentration measured, analysis indoor and outdoor fine particulate matter pollution correlation, and determine the relevant factors.
