How it works
Each VAV diffuser is an independent zone of variable air volume control with individual room thermostats and built-in modulating dampers for varying the air volume. The dampers are continuously adjusting to vary the volume of air flow (warm or cold) into the room, in response to room temperature. Unlike fixed opening diffusers, which dump cold air on occupants at low volumes, the variable air opening within all of our diffuser models creates high discharge air velocity even at lower supply volumes. This maintains the Coanda effect where high velocity air hugs an adjacent surface, holding cold air up to the ceiling and prevents dumping.
Personal comfort and control is possible. Our diffusers act as an individual VAV zone of control, providing temperature settings maintained within 1½°F/0.9°C. No dumping, high discharge velocity, persistent throws, better room air movement and uniform temperature distribution define an optimized environment.
Unlike a fixed-grill diffuser, each of our Acutherm VAV diffusers are a self-contained zone of control with individual thermostat and built-in VAV mechanisms. The system is accessible from the room-side, unlike other devices, which require above-ceiling access for ongoing maintenance and calibration. Both on a first installed cost and ongoing operational basis, our VAV diffusers are the most economical way to improve comfort and energy savings.
As U.S. Green Building Council members, Acutherm is proud to produce low pressure, energy-efficient, VAV diffuser systems that prevent overcooling and overheating – resulting in 10%-31% energy savings, when compared to other HVAC systems.
Sustainability and Integration
Sustainable buildings are designed to be environmentally responsible and resource-efficient throughout their lifecycle. For sustaining long-term usefulness, our VAV diffuser systems are modular and adaptable to layout and programming changes, while influencing up to 21 LEED® credits.
