Characteristics of the Concentration Change of the Particulate Matter in the Indoor and Outdoor Existing Public Office Buildings

In order to clarify the influence of outdoor inhalable particulate matter on the interior of existing public office buildings in Cold area, this paper uses the method of weight method and instantaneous detection to measure the indoor and outdoor inhalable particulate matter concentration of two existing office buildings in Shenyang in summer. The changes of daily average, instantaneous concentration and I/O ratio of PM2.5 and PM10 in the indoor and outdoor are analyzed, and the influence of outdoor particulate matter on the concentration of indoor and outdoor inhalable particulate matter in two buildings was analyzed by analyzing the correlation of indoor and outdoor concentration change and regression. This paper provides a reference for the study of the different airtight buildings on the barrier properties of outdoor inhalable particulate matter and the improvement of the indoor environment quality.
