洁净室人员发尘规律研究
Study on human particle emission rates of cleanrooms
摘要：
由于计算方法的不完善和人员发尘量的不确定，设计人员为了安全，往往采用过大的换气次数，造成了洁净室能源浪费。为了解决这一问题，本研究从洁净度保障原理出发，系统地介绍了洁净室换气次数的计算方法，通过国内外文献调研及分析，探究了人员作为颗粒物发尘主体的特点，得到了人员发尘的粒径特征及发尘量与人员数的非线性规律，对比分析了目前洁净室内的人员发尘当量，总结了洁净室内人员发尘的主要影响因素。发现随着洁净度的降低、洁净服材料的过滤效果变差、洁净服洗涤次数增多、活动强度增大，人员发尘量会增加。研究成果可供洁净室换气次数精准设计参考。
Abstract：
Due to the imperfection of the calculation method and the uncertainty of the amount of dust generated by personnel, designers often use excessive air change rates for safety, resulting in a waste of energy in the cleanroom. In order to solve this problem, this study systematically presents the calculation method of air change rate in cleanrooms based on the principle of cleanliness guarantee. Through the investigation and analysis of domestic and foreign literature, it explores the characteristics of personnel as the main body of particulate dust, obtains the particle size characteristics of personnel dust and the nonlinear law between the amount of dust and the number of personnel, compares and analyses the current dust equivalent of personnel in cleanrooms, and summarizes the main influencing factors of personnel dust in cleanrooms. It is found that with the decrease of cleanliness, the poor filtering effect of clean clothes materials, the increase of washing times and activity intensity of clean clothes, the amount of dust generated by personnel will increase. The research results can be used as a reference for the accurate design of air change rate in cleanrooms.
