Displacement ventilation for industrial applications: types, applications, and design strategy

摘要

Unlike mixing- (dilution-) type ventilation and air-conditioning systems, which produce fairly uniform temperatures, humidities, and contaminant concentrations throughout all areas and levels of a room, displacement-ventilation systems create stratified levels of temperatures and contaminant concentrations. This article discusses types of displacement-ventilation systems, applications for which they are suited, and a strategy for implementation.
