【摘要】：办公建筑室内空气质量是直接影响人们身体健康和工作效率的重要因素,而颗粒物污染是表征办公建筑空气质量好坏的重要指标。近年来,办公建筑室内颗粒物污染越来越严重,却还没有引起人们足够的重视。本文正是在这样的背景下对有效控制办公建筑室内空气污染的方法及其净化性能进行研究。本文首先对办公建筑室内颗粒物污染来源、现状做了分析及测试,阐述了现代办公建筑颗粒物污染的严重性。其次针对控制办公建筑颗粒物污染的空气净化器的性能参数进行了探讨,分析了评价空气净化器性能的参数及其影响因素,通过建立空气净化器测试理论模型并在30m3大型室内空气质量实验舱中对影响其性能的因素进行了实验,重点对影响CADR的不同尘源、风速、评价方法进行了讨论。最后对应用在办公建筑新风系统中的空气过滤器进行了详细介绍,并研制了一般通风用空气过滤器性能实验台,主要由风机箱、喷嘴箱、气溶胶发生系统、人工尘发生系统、粒子采样系统、阻力测试系统和末端过滤器等组成,并对影响实验台的发尘因素进行了探讨,本实验台性能稳定,操作便捷,有益于对空气过滤器性能的测试,对空气过滤器的性能参数阻力、计径计数效率、容尘量的影响因素等进行了探讨。在对实际办公建筑颗粒物过滤性能的测试中发现,空气净化系统能有效控制办公建筑室内颗粒物污染。
[Abstract]:Indoor air quality in office buildings is an important factor that directly affects people's health and working efficiency, and particulate pollution is an important indicator of air quality in office buildings in recent years. Indoor particulate pollution in office buildings is becoming more and more serious. However, people have not paid enough attention to it. In this paper, the methods and purification performance of indoor air pollution control in office buildings are studied. Firstly, the indoor particulate pollution in office buildings is studied in this paper. Source. The present situation is analyzed and tested, and the seriousness of particulate pollution in modern office buildings is expounded. Secondly, the performance parameters of air purifier for controlling particulate pollution in office buildings are discussed. The parameters of evaluating the performance of air purifier and its influencing factors are analyzed. The test model of air purifier is established and the factors that affect the performance of air purifier are tested in a large indoor air quality test module of 30 m ~ 3. The different dust sources, wind speed and evaluation methods that affect CADR are discussed in detail. Finally, the air filter used in the office building fresh air system is introduced in detail. And a general ventilation air filter performance test bench is developed, which is mainly composed of fan box, nozzle box, aerosol generating system, artificial dust generation system, particle sampling system, resistance testing system and end filter. The paper also discusses the factors that affect the dust emission of the test bench. The performance of the test bench is stable and easy to operate, which is beneficial to the testing of the performance of air filter, the resistance of air filter performance parameters and the counting efficiency of diameters. In this paper, the influence factors of dust capacity are discussed. In the test of filtration performance of particulate matter in practical office buildings, it is found that the air purifying system can effectively control indoor particulate pollution in office buildings.
