Product Description

The Holyoake DS Series of supply diffusers operate on the principles of Displacement Ventilation. Displacement Ventilation is essentially a buoyancy driven displacement process where supply air at a temperature slightly cooler than the design room air temperature is delivered into the room at low level. The cool air spreads across the floor only rising when it comes into contact with a heat source such as a human. The heated air rises and will exit the room via openings at ceiling level, taking with it any pollutants that have been picked up on the way.

Holyoake DS Displacement Diffusers have been designed to enable step mounting, although they can also be used in many other locations.

They are ideally suited for use in Auditoria and Theatres. Typically these spaces contain a large volume of space that although not occupied is still typically conditioned. By introducing the conditioned air unobtrusively from directly behind the occupants only the space around the patrons is conditioned rather than the whole auditorium. This ensures that the occupied space is kept at ideal conditions whilst not wasting energy maintaining the whole space at design conditions.

Product Specification

Displacement Diffusers shall be Holyoake Series DS. They shall be designed to mount into a supply plenum at floor level and to provide an even distribution of air flow at low velocity, thereby creating a draft-less environment. Pressure drop through the displacement diffusers will be such to provide balance within the supply plenum while being low enough to generate very low noise levels. The displacement diffusers will be designed to be face fixed or supplied with the Holyoake Removable Core System. All shall be as manufactured by Holyoake.
