通风管道中颗粒沉积的实验研究

通风与空调系统中的风管系统（简称：通风系统）内的颗粒沉积会对室内人员造成严重影响,同时还会降低通风与空调系统的性能,甚至导致室内二次污染。如果清楚了通风管内何处沉积着或易于沉积有害气溶胶,就能在最初设计通风系统时多加注意,在设计阶段就应该尽量减少它们的沉积,同时还可以提高建筑补救效率以及降低相关费用。掌握通风管道中颗粒沉积的知识不仅对模拟建筑内颗粒情况有帮助,还可以更加充分地了解颗粒运动情况。

Experiments of Particle Deposition in HVAC System

Particle deposition in HVAC system may be harmful to residents, and it may reduce its performance, even lead to second contamination. Knowing clearly where aerosols deposit, people could pay more attention to HVAC system design process to reduce its deposition. This step can also enhance building remediation efficiency and reduce its remediation cost. Mastering the knowledge of particle deposition in HVAC system ducts may be helpful to model the fate of particles indoors, and could know more about particles movement.
