空气过滤器是控制室内颗粒物污染的主要设备,但工程设计中仍然存在诸多问题。为了方便设计人员进行空气过滤器选型与校核计算,利用理论计算与工程实际相结合的方法,给出了部分公共建筑典型工况下主过滤器效率计算的图解法。介绍了该图解法的具体使用步骤与使用方法,并分析论证了选型计算的合理性。最后利用一个工程实例展示了其应用的可行性。 Air filter is the main equipment to control the indoor pollution of particles, but engineering design there are still many problems. In order to facilitate the design of air filter selection and check calculation, the use of theoretical calculations combined with the actual project is given in some public buildings under the conditions of the main filter efficiency calculation diagram. The specific steps and methods of using this method are introduced, and the rationality of the method is also demonstrated. Finally, an engineering example is used to demonstrate the feasibility of its application.
