建筑室内PM_(2.5)污染控制设计计算方法提出的时间相对较短,室内PM_(2.5)污染源负荷的计算方法有待完善。本文以北京市某办公建筑半集中式空调系统为例,初步提出室内PM_(2.5)污染源负荷“同时发生系数”的计算方法,并对室内PM_(2.5)污染控制进行相关设计。半集中式系统PM_(2.5)污染控制设计时,分别计算新风系统和室内空气处理系统去除的PM_(2.5)负荷,室内空气处理系统需扣除新风承担的室内PM_(2.5)负荷。该设计探讨旨在为我国相关工程应用提供参考。
The proposed method of PM_ (2.5) pollution control design and construction method is relatively short, and the calculation method of indoor PM_ (2.5) pollution source load needs to be improved. Taking a semi - centralized air - conditioning system of an office building in Beijing as an example, this paper initially puts forward the calculation method of indoor PM 2.5 pollutant load “Coefficient Coefficient ”, and carries out relative design of indoor PM 2.5 pollutant control. For the PM 2.5 pollution control design, the PM 2.5 load removed by the fresh air system and the indoor air handling system were separately calculated and the PM 2.5 indoor load borne by the fresh air was deducted from the indoor air handling system. The design of the study aims to provide reference for the application of related projects in our country.
