摘要
空调系统通风管道尘粒的沉积会降低空调系统的性能并影响室内空气品质,掌握含尘气流的流动、沉降规律及在各式结构通风管道中的尘粒沉积规律,对于管道清洁及采取相对应的处理、控制措施减少管道积尘有着重要意义。本文主要对通风管道影响尘粒沉积的诸因素,如尘粒粒径、送风风速和管壁粗糙度等进行了探讨,并对目前有待研究的问题进行了展望。
Particle deposition in ventilation duct can decrease the performance of air conditioning system and impact the indoor air quality.It is important to investigate the mechanism of the flow and deposition of dust in different duct configuration because these understandings are useful for duct cleaning and taking measures to decrease particle deposition.The parameters of particle deposition in duct such as particle diameter,air velocity and duct roughness were discussed in this paper besides the further reached problems were put forward.
