建筑新风量是影响室内空气质量的重要因素,并进而可能对人体健康、室内舒适性和工作效率产生影响。同时,建筑新风量又会影响建筑供暖或空调能耗。对天津市300余户居住建筑的室外新风量进行了测量与分析,介绍了针对自然通风系统测试的CO_2方法。为我国居住建筑新风量测试的深入开展提供必要的依据,并为控制和改善室内空气质量提供技术参考。
Building fresh air volume is an important factor affecting the indoor air quality, which in turn may have an impact on human health, indoor comfort and work efficiency. At the same time, building fresh air volume will affect the building heating or air conditioning energy consumption. The outdoor fresh air volume of more than 300 residential buildings in Tianjin was measured and analyzed. The CO_2 method for natural ventilation system testing was introduced. Provide the necessary basis for the in-depth test of new air volume test of residential buildings in our country, and provide technical reference for controlling and improving the indoor air quality.
