北京市一些高级办公大楼室内空气质量问题探讨

Study on some problems of TAQ in high grade office buildings in Beijing

我们调查了北京一些高档的空调建筑,包括商业和政府机构办公大楼,测试了主要的室内污染和室内气象参数,如温度、湿度、风速等。测试结果指出,在这些建筑中存在着严重的室内空气质量问题。而且,引起不良室内空气质量的原因不是单一的而是多方面的。因此如何提高室内空气质量,为人们提供健康而舒适的室内环境,是空调设计者的迫切任务。

We investigated some high - level air conditioning buildings, including commercial and government office buildings in Beijing, and several main indoor contaminants and indoor microclimate parameter such as temperature, humidity and air flow velocity were measured. Test results indicated that senous problems of indoor air quality existed in those building, as well as, reasons which caused poor indoor air quality were made up of manifold factors, not single one, as follows: Building and decorative materials become one of main pollution sources. Distribution of airflow patterns in most of air conditioning rooms is not rational , becauses of bad air conditioning design. Fresh air rate and air change rate are not enough. The operation and management of air conditioning system are poor. so how to increase indoor air quality, providing a health and comfortable indoor environment for the people working in those magnificent office building is an urgent and challenging task for the air conditioning designer.
