城市公交空调车内空气品质测试分析

Investigation of the Inside Air Quality of Air Conditioned Buses

对上海市公交空调客车车辆内环境质量进行了测试。测试指标包括温度、湿度、CO、CO2和甲醛等指标。测试分析表明:车辆的室内温湿度一般满足人体热舒适的要求,而车内空气品质很差。公汽内CO2浓度高达3223ppm以上,CO高达18ppm,甲醛浓度也较高。对空调公交汽车的空气品质有待改进。

The inside microenvironment parameters of air conditioned buses in Shanghai were measured. These measured parameters are temperature, humidity, CO, CO2, and formaldehyde. The results show the inside-vehicle temperature and humidity for these vehicles can basically meet the needs of human＇s thermal comfort. However, the inside-vehicle air qualities are not content CO2 concentration for bus is up to 3223 ppm, CO 18ppm, and formaldehyde higher. Therefore, air quality for bus should be improved.
