HVAC diffuser are the vent covers through which climate-controlled air is delivered to a room, floor, wall, ceiling and other space. It’s commonly use in both commercial and residential buildings.
HVAC diffuser is a device that to reduce the velocity and increase the static pressure of air flow passing through a system. The fluid static pressure rise as it passes through a duct is commonly referred to as pressure recovery. In contrast, a nozzle is used to increase the discharge velocity and lower the pressure of a fluid passing through it.
The hvac diffuser are very common in heating, ventilating, and air-conditioning systems. They are used on both all-air and air-water HVAC systems, as part of room air distribution subsystems.
The conditioned air produced by HVAC systems requires correct introduction into any space for it to realize its full potential. Haphazard conditioned air inflow into a room can cause localized hot and cold spots and completely rob the area of much of the benefit of heating and ventilation. Uncontrolled inflow of air can also be annoyingly noisy. HVAC diffusers reduce the velocity of the incoming airflow and direct it to ensure effective mixing and maximum benefit with minimum noise.
As the air diffuser are designed in a way that they have openings in all directions, the build-up of pressure in the diffuser causes the air to leak out in all directions, thus regulating it evenly in the whole room.
Generally air diffusers can be of various types depending upon the shape and the way of letting the air pass through them.The hvac diffuser have three main types.The are air diffuser, air grilles and air louver.The air diffuser included square diffuser, round diffuser, jet nozzle diffuser, slot diffuser.,swirl diffuser and drum diffuser. The air grilles included double deflection grille, single deflection grille, return air grille, linear bar grille, egg crate grille , floor grille and door grille. The air louver have weather louver,gravity louver and ball louver. And we also have other accessories such as volume control damper, plenum box,aluminum tape and flexible duct.
The performance of the HVAC diffuser should be at a high level. It have the ability to perform two functions efficiently, that’s distributing the air throughout the area in a balanced and evenly way while mitigating the noise as much as possible. Usually for high ceiling use square diffuser, round diffuser, jet nozzle diffuser,swirl diffuser, slot diffuser and linear bar grille. For wall and duct we use supply and return air grilles. And for outdoor air ventilation usually use weather louver or door louver.
