中文摘要:
      CO2浓度是评价室内空气质量的重要指标之一,控制较低的室内CO2浓度对室内空气质量和人的身心健康起着重要作用.对大连市某小区室内CO2浓度的变化情况进行了连续监测.通过设置不同开窗状态,分别监测了该小区室内不同条件下的CO2浓度变化.结果表明,CO2浓度随时间和通风情况呈现出不同的变化趋势,室内不同位置的CO2分布特性也有所不同.密闭情况下,时间越长,室内CO2浓度越高.当进行自然通风时,即使较短的开窗时间也能使室内CO2浓度迅速降低.研究表明,保持良好的室内通风,选择性开窗对降低室内CO2浓度、保持较好的室内空气质量有着重要作用.
英文摘要:
      CO2 concentration is one of the important indexes to evaluate indoor air quality, and keeping a low indoor CO2 concentration is very important to improve indoor air quality and maintain physical and mental health. The change of CO2 concentration in the residential building of Dalian city is monitored continuously. By setting different window conditions, the change of CO2 concentration is monitored in different locations in the building. The result shows that the CO2 concentration has different change trends with time and indoor ventilation, and the distribution characteristics of CO2 are also different at different locations. When the windows are closed, the longer the time is, the higher the indoor CO2 concentration is.But even a short opening time can make the indoor CO2 concentration decrease rapidly. Keeping good indoor ventilation and windows opening for fixed time have a significant effect on reducing the indoor CO2 concentration and keeping good indoor air quality.
