Chair fan-enhanced displacement ventilation for high IAQ: Effects on particle inhalation and stratification height

It was found that with the appropriate selection of the CF flow rate, it is possible to realize a 30% reduction in DV energy use for a given level of thermal comfort and IAQ covering the inhalable particle range. Interestingly, oversized CF can result in increased contaminant exposure relative to the DV-only system. We report CF selection methodology to avoid this outcome.
