大型商业综合体室内空气质量与新风阀开度研究

STUDY ON INDOOR AIR QUALITY AND FRESH AIR VALVE OPENING IN LARGE COMMERCIAL COMPLEX

大型商业综合体属于人流量大的公共场所,建筑内部结构设计相对封闭,采取适当和有效的通风策略成为保证室内良好的空气质量、提升大型商业综合体的服务和运行管理的重要措施。现有空调系统中风阀调节均采用人工调节开度的方式,无法随环境变化而自动调整风阀开度,且新风与回风的配比无法相应变化,因此,有必要对新风阀开度进行深入研究。

Large commercial complex is a public place with large population flow.The internal structure design of the building is relatively closed.Taking appropriate and effective ventilation strategies has become an important measure to ensure good indoor air quality and improve the service and operation management of large commercial complex.In the existing air conditioning system,the wind valve opening is manually adjusted,which cannot be automatically adjusted with the change of environment,and the ratio of fresh air to return air cannot be changed accordingly.Therefore,it is necessary to conduct in-depth research on the opening of fresh air valve.
