Ventilation by displacement; its characteristics, design and other related developments.

Author(s) : LI Y., DELSANTE A. E., SANDBERG M.

Type of article: Article

Summary

Simple engineering models are summarised for predicting near-field length, airspeed in the far-field, air temperature in the occupied regions, the vertical air temperature gradient, concentration in the polluted region, the clean zone height and the cooling loads. Two major design parameters from both indoor air quality and thermal confort points of view are the clean zone height and the vertical air temperature gradient. Some design aspects have been discussed. Other related developments covered briefly here include the effects of moving bodies, near-body natural convection flows, raised floor systems and chilled ceiling systems.
