总结了ASHRAE RP-531中执行的工作，并提出了在再循环系统中使用工业除尘器尚未解决的一些问题。概述了除尘器的参数研究以及其他系统组件（如罩和传感器）的工作。声明说，这些额外的研究将帮助制造商和系统设计师建造和运行符合适用OSHA和NIOSH指南的工业空气净化系统，并将能源使用和运行成本降至最低。关键词:工业，工厂，除尘器，空气，再循环，空气净化，空气过滤器，灰尘。 引用:研讨会论文，佐治亚州亚特兰大，1990年

Summarises the work performed in ASHRAE RP-531 and presents a number of issues that are not resolved concerning the use of industrial dust collectors in recirculation systems. Outlines parametric studies of dust collectors and work on other system components, such as hoods and sensors. States that these additional studies would help manufacturers and system designers construct and operate industrial air cleaning systems that meet applicable OSHA and NIOSH guidelines with a minimum amount of energy use and operating cost.KEYWORDS: Industrial, factories, dust separators, air, recirculating, air cleaning, air filters, dust.
