教学机房室内空气品质现状调查及改善措施

教学机房是学生学习的重要场所,也是集中授课的重要场所之一.机房内人员多,电子设备多,室内照明要求高,因此室内负荷大.目前许多教学机房是对教室或其他场所改造而成的,原来室内无空调通风措施.改造后的机房多数是在室内安装空调器试图降低室内温度,但是受空调器安装位置限制,室内温度场分布不均匀.同时为减少耗电量,房间门窗一般关闭,只设置排气扇进行通风换气,室内空气品质较差.本文通过对某典型教学机房室内空气品质中部分主要指标进行现场测试及问卷调查,发现机房内空气品质较差,分析了原因,并提出了改善措施.

Investigation and Improving Measures of Indoor Air Quality of A Teaching Computer Lab

Many teaching computer labs are transformed from classrooms or other places. There are no air conditioning or ventilating facilities in the room originally. In the computer lab there are many people, electronic equipments and lights, so cooling loads are great. Most of the computer labs install the air conditioner to reduce the indoor air temperature. Because of the limited installation site of the air conditioner, the distribution of temperature is not even in the indoor temperature field. At the same time, the doors and windows of the room are generally closed in order to reduce the power consumption, only set up the ventilation fan to ventilate and take a breath. Thus indoor air quality is relatively poor. Through carrying out on-the-spot test and questionnaire investigation to some major indicators in some typical teaching computer lab, finds indoor air quality is very poor in it, then analyses the reasons, and proposes the improving measures.
