天津市居住建筑新风量的测量与分析
Measurement and analysis of outdoor air rate of residential buildings in Tianjin
摘要：
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CO2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。

Abstract：
Outdoor air rate is an important factor, which can affect the indoor air quality, people’s health and work efficiency as well as energy consumption of heating and cooling system in buildings. Systematically measures and analyses outdoor air rate of residential buildings in Tianjin. And presents the CO2 method for testing the natural ventilation system. Provides the necessary basis for the further development of the outdoor air rate test in residential buildings and technical reference for the control and improvement of indoor air quality.
