Abstract

In the severe cold regions of northeast China, the outdoor temperature conditions are harsh in winter and concentrated coal-fired heating is used, which causes the indoor fresh air requirements cannot be guaranteed in residents in winter. At the same time, as people pay more attention to interior decoration, indoor air quality is receiving more attention. Herein, using spectrophotometric method, GC-MS (Gas Chromatography-Mass Spectrometer) method, TSI DustTrak particle tester and Telaire 7001 CO2 tester, we investigated the concentration change of formaldehyde (HCHO), volatile organic compounds (VOCs) PM2.5 and CO2 of 33 houses for winter under 2 conditions (airtight and natural ventilation). What’s more, the natural infiltration rates of them were also measured by using CO2 as tracer gas in the national standard method. Through the test and long-term monitoring data, the main pollution problem in winter is the indoor TVOC and PM2.5, and the indoor HCHO concentration of the house using the wallpaper in the decoration is much higher than that of other decoration methods. The pollution problem under natural ventilated conditions has been greatly reduced, so residents should open windows more under the conditions allowed by outdoor environmental conditions.
