horizontally into a ceiling or bulkhead, they can be fitted into a sidewall. Across the floor plan, conventionally swirl diffusers are chosen, but again their location is vital. Set them too close, and the swirling, omni-directional air streams will buffet each other, causing unwelcome draughts for the occupants and throwing airborne pollutants around. Manufacturers are coming up with new techniques to further enhance the performance of ADUs to help everyone involved in the building achieve good IAQ and relative humidity (RH) without comprising energy consumption. Now, diffusers are available with multiple, individually adjustable
nozzles, so the incoming air can be directed with pinpoint precision.
Slot and swirl diffusers now also feature thermal adjustability: as the temperature varies inside, so the diffusers automatically adjust to change the airflow direction. It all happens without any electricity and within seconds – to the extent the occupants do not even notice the drop or rise in temperature. The Gilberts Blackpool ThermAstute® range is, we believe, unique in that it brings that degree of temperature control to slot diffusers as well as swirls. As a result, the ability to balance airflow and energy consumption within the building is not restricted by the type of air distribution. There’s more good news too. You can ‘tick the box’ in terms of getting the heating, ventilation and damp-proofing right and still create an interior that looks amazing. The face plate of the grille or diffuser can be a key part of the
interior design. Today it’s possible not only to choose the colour, but the finish – we can even create metallic or marble effects. The face plate can be tailored to your bespoke design, featuring a logo or brand name. With swirl diffusers in exposed ceiling, the Coanda plate can be manufactured from almost any material you like (subject to the appropriate fire regulation etc): we’ve even backlit them. The result is, where the HVAC is concerned, there is no need to
compromise. You can achieve a highly energy-efficient solution, that improves the health of occupants and building and combine form with function. All you need to do is talk to the right people, those who you can trust and who know how to achieve a comfortable warm and dry environment whilst balancing your specification criteria. (1)
