指ASHRAE研究项目RP-531，该项目已证明了工业除尘器再循环的可行性，以降低通风系统的能源需求。扩展RP-531的数学建模工作，以显示再循环如何影响颗粒物和气相。说明结果表明，当充分清除颗粒物的收集器空气再循环时，很容易遇到空气质量问题。关键词:工业，可行性，除尘器，计算，颗粒物，灰尘，气体，室内，空气污染，空气，再循环，健康，危害。引用:研讨会论文，佐治亚州亚特兰大，1990年

Refers to ASHRAE Research Project RP-531, which has demonstrated the feasibility of recirculation from industrial dust collectors to reduce energy requirements of ventilation systems. Expands the mathematical modelling work of RP-531 to show how recirculation affects both particulate and gas phases. States the results signal that air quality problems can very readily be encountered when collector air, adequately cleaned of particulates, is recirculated.KEYWORDS: Industrial, feasibility, dust separators, calculating, particles, dust, gases, indoor, air pollution, air, recirculating, health, hazards.
