夏热冬冷地区中小学绿色建筑通风设计探讨

Ventilation Design of Green Building in Primary and Middle Schools in Hot Summer and Cold Winter Zone

中小学建筑作为青少年日常主要活动场所,其每天在教室停留的时间长达5个多小时。教室中室内污染物含量的高低直接影响着学生学习和身体状况。因此,建筑设计时应综合考虑各方面因素,确定合理有效的通风方式,当采用机械通风方式时,新风量应不小于22~28 m3/h·人,化学、物理教室换气系数不应低于3次/h;采用自然通风方式时,夏热冬冷地区应优先采用外走廊设计。

The buildings in primary schools and secondary schools are mainly active places for teenagers.They stay in classrooms for over five hours a day.The content of indoor pollutant in the classrooms has a direct impact on students’learning status and physical condition.Therefore,the design of architecture should take all factors into consideration to find a reasonable and effective ventilation way.Fresh air volume should be greater than 22~28 m 3/h per person when using mechanical ventilation system,ventilation coefficient should be greater than three times/h in chemical and physical classrooms;when using natural ventilation,the teaching building in Hot Summer and Cold Winter Zone should be preferred outside corridor layout.
