Abstract

States that in buoyancy-driven, displacement ventilation, the incoming 'fresh air' is gently introduced near the floor at a temperature slightly lower than the design room air temperature. The cool air flows slowly over the floor and air that has become warmed rises above the cool layer. Any local heat sources in the lower part of the room create convection currents that also contribute to the general upward movement and the air is ultimately exhausted at high level. Supplies up-to-date information on the application of this type of ventilation and data appropriate to the design and operation in the UK. Section headings are - Design concept, Application, Significant parameters, Design strategy, Numerical modelling.
