城市地下空间复合净化装置设计方法探讨
Design method of combined air cleaners in urban underground spaces
摘要：
城市地下空间通风空调系统设计应兼顾热舒适性及空气质量。为有效去除地下空间的污染物，提出了城市地下空间各组分污染物的净化效率确定方法，以采用一次回风全空气系统的某地下商场为例，给出了所需复合净化装置的净化效率的计算步骤，总结出复合净化装置的一次净化效率的确定原则；探讨了复合净化装置的设计原则，研发了适用于地下空间的复合净化装置样机，并检测了其净化性能。在此基础上，对样机作为地下商场回风段净化装置的净化效果进行了模拟分析，结果表明，复合净化装置能较好地保障地下空间工作区的空气品质。
Abstract：
The thermal comfort and air quality assurance should be considered together in the design of the ventilation and air conditioning system for urban underground spaces(UUS). In order to remove pollutants effectively in UUS, develops a determining method for clean efficiency of different pollutants. Taking an underground store using all air system with primary return air as example, gives the calculation steps of clean efficiency of the combined air cleaners (CAC). Summarizes the determining principles for primary clean efficiency of the CAC. Discusses its design principle. Develops the prototype of CAC for UUS and tests its cleaning performance. Carries out the simulation and analysis on the cleaning effect when the prototype is used as the cleaning device of return air section for the UUS. The results show that the air quality of workspace can be well ensured with the CAC.
