HVAC diffusers are the outlet points for heating, ventilation and air conditioning units. A diffuser is used in both residential and non-residential buildings with the main purpose of distributing fresh air into a room making as little noise as possible. As part of air circulation subsystems, an HVAC serves other functions as well. It helps in delivering even air flow into the desired area, enhances the mixing of discharged air with the room air, and it decreases the velocity of the incoming air.
Also referred to as ventilation diffusers, they are available in many standardized styles, sizes, and shapes – round, square and rectangle. Diffusers are commonly installed in floors or ceilings of a building. They are usually made of wood or metal materials, with wood being normally less utilized and rarely found inside a home.
Residential HVAC diffusers come in variety of designs that can easily compliment a house decor. Mostly, the diffusers used are of rectangular shape with venting on the top and a damper inside to control air passage. These domestic diffusers are also termed as registers. As for industrial HVAC diffusers, square-shaped diffusers are popularly used for they are designed to correctly fit into the framing of ceiling tiles. These diffusers are attached to the insulated tubes of HVAC systems.
There are differences between the two diffuser types. A residential diffuser comes with a slide to allow the diffuser to block the moving air from entering the room in which it is installed. On the other hand, an industrial diffuser is placed in an open fixed position with airflow being decided by the HVAC unit.
