摘　　要：为了研究办公场所纤维风管系统送风时的气溶胶分布情况,采用Fluent软件,针对风机盘管送风系统和纤维风管送风系统在不同的运行工况下,对办公场所室内速度场和气溶胶浓度分布情况进行数值模拟,并进行实验验证。通过分析速度场和气溶胶浓度场的分布特点,比较得出纤维风管送风系统下气溶胶分布效果优于风机盘管送风系统,且送风速度的增加能有效降低气溶胶质量浓度。采用纤维风管送风系统时,在一定范围内增加送风量可降低室内气溶胶质量浓度,进而可改善室内空气品质。结果表明,相比于风机盘管送风系统,将纤维风管送风系统应用在办公场所具有“独特”的优势。To research the aerosol distribution in office space under the air supply mode of the fiber duct system,Fluent software is used to simulate the velocity field and aerosol concentration distribution in office space,under different operating conditions of fan coil air supply system and fiber duct air supply system,and experimental verification is carried out.By analyzing the distribution characteristics of velocity field and aerosol concentration field,it is concluded that the aerosol distribution effect of the fiber duct air supply system is better than that of the fan coil,and the increase of air supply speed can effectively reduce the aerosol mass concentration.Using the fiber duct air supply system,increasing the air supply volume within a certain range can reduce the indoor aerosol mass concentration,which in turn can improve indoor air quality.The results show that the fiber duct air supply system has"unique"advantages than the fan coil in the office.
