Ventilators should incorporate appropriate grilles which prevent the entry of vermin to the sub-floor but do not resist the air flow unduly.

Many elements, including the ceiling peak, diffuser traits, number of diffusers, provide air temperature, complete flow rate, cooling load and conditioning mode affect the ventilation efficiency of UFAD methods. Additionally, ground diffusers add a component of non-public control within the attain of the occupant, as users can regulate the amount of air that is delivered by the diffuser although rotating the diffuser prime. The theoretical conduct of UFAD systems relies on the plume principle for DV methods.
