Price Displacement Ventilation

Displacement ventilation is an air distribution strategy that introduces cool air into a zone at low velocity, typically at low level. The cool air, typically between 62-68F, pools at floor area, where it is then carried up in the thermal plumes generated by heat sources. Displacement ventilation diffusers are known for their low acoustic footprint and comfortable delivery of air. Designers must use care to design air-handling unit systems to deliver air at elevated temperature, without reducing dehumidification potential. Return air bypass is often required, to minimize the need for reheat. Close coordination with architecture is also required, as diffusers require a large free area to maintain a displacement supply air effect.

Displacement ventilation is now common for performing arts centers, as well as classrooms and conference rooms.
