摘要
为改善严寒地区住宅冬季室内的空气品质,为室内人员提供舒适、健康的居住环境,本文采用数值模拟的方法,对自然通风条件下,换气时间对室内温度和CO2浓度分布的影响进行了分析。通过建立不同通风换气时间、室内温度和CO2浓度变化的对比工况,得出对于冬季采暖房间最佳的通风换气时间为上午9:00~10:00。
In order to improve indoor air quality and provide a comfortable environment for people in the room, the paper analyzed the effect of ventilation time on the distribution of indoor temperature and CO2 concentration by using numerical simulation method. Comparison of ventilation time, indoor temperature and CO2 concentration under different conditions shows that the best ventilation time for winter heating room is 9:00~10:00.
