减少断面风速,采用两侧墙下部回风是降低垂直层流洁净造价和运行费的关键所在。本文通过大量实验对垂直层流洁净室断面风速,气流组织和洁净度之间的关系进行了分析并得出相应的结论。 Reducing the cross-section wind speed and using the return air from the lower part of both sides of the wall are the keys to reducing the cost of clean laminar flow and operating costs. This article analyzes the relationship between the cross-section wind speed, airflow organization and cleanliness of the vertical laminar flow clean room through a large number of experiments and draws corresponding conclusions.
