城市居住建筑室内CO2分布特性研究
Study of distribution characteristics of CO2 in urban residential buildings
摘要
Abstract
CO2 concentration is one of the important indexes to evaluate indoor air quality,and keeping a low indoor CO2 concentration is very important to improve indoor air quality and maintain physical and mental health.The change of CO2 concentration in the residential building of Dalian city is monitored continuously.By setting different window conditions,the change of CO2 concentration is monitored in different locations in the building.The result shows that the CO2 concentration has different change trends with time and indoor ventilation,and the distribution characteristics of CO2 are also different at different locations.When the windows are closed,the longer the time is,the higher the indoor CO2 concentration is.But even a short opening time can make the indoor CO2 concentration decrease rapidly. Keeping good indoor ventilation and windows opening for fixed time have a significant effect on reducing the indoor CO2 concentration and keeping good indoor air quality.关键词
