Underfloor Ventilation

The theoretical behavior of UFAD systems is predicated on the plume theory for DV techniques. In comparison to traditional displacement air flow systems that deliver air at low velocities, typical UFAD techniques ship air via floor diffusers with greater supply air velocities. In addition to increasing the quantity of mixing , these extra highly effective provide air situations can have vital impacts on room air stratification and thermal comfort within the occupied zone. Therefore, the control and optimization of this stratification is crucial to system design and sizing, vitality-efficient operation, and comfort efficiency of UFAD techniques. UFAD methods capitalize on the natural stratification that happens when warm air rises because of thermal buoyancy. The temperature stratification created by the UFAD system has implication for area setpoints.
