Abstract
Recirculation of industrial exhaust air to reduce energy consumption in heating or cooling workplace air is discussed in a paper presented at a symposium held October 6-7, 1977 in Cincinnati, Ohio. Air cleaning equipment (ACE) is an essential component of recirculation systems which must be designed to prevent occupational health problems. Primary system components are ACE and monitoring/alarm equipment. Monitoring equipment requires significant development work for safeguarding recirculation systems. Where recirculation is proposed, each case must be evaluated on its own merits. If feasibility is established, ACE must be properly selected to remove specific contaminants. ACE is normally designed for the removal of particulates or gases and vapors. Equipment considered to have potential for recirculation design include: 1) absorbers/wet collectors; 2) absorbers; 3) electrostatic precipitators; and 4) fabric filters. For each of these types of equipment collection mechanisms, equipment configuration, performance capability, and applicability to recirculation is reviewed. Presently available options and future research needs are presented. It is concluded that a comprehensive engineering design approach to ACE is needed with major research and design of air cleaning equipment to improve its overall capability.
