Choosing your air supply diffusers for Ducted Systems

 

Homeowners have a number of choices when it comes to choosing a ducted air conditioning system but also many choices with the ceiling or wall air diffusers that are available.

Essentially, diffusers are the grills or vents where air supply is diffused through.  Diffusers help to control air flow and speed of air to mix optimally with the indoor environment. They also can direct the air in desired directions.  Depending on the size of the room and the individual design preferences of homeowners there are many things to consider when deciding on these.

H&H Air Conditioning gives an overview of some of the different types of diffusers in our latest post.

ROUND DIFFUSER:

One of the most popular diffusers, the round diffuser offers 360 degree air flow with streamlined looks. It’s architecturally popular as it looks the same in any direction. Depending on the size of the room, there can be single or multiple diffusers used. Many circular diffusers have a fully adjustable core which can control air volume.

SIDE WALL BAR GRILLE

Located high on a wall towards the ceiling, side wall grilles or linear slot diffusers are used when the ducted system is located behind the wall rather than in the roof. They can have up to eight slots and different blade profiles that can be adjusted to vary the air flow.

 

RETURN AIR GRILLES

Often located in hallways or in the ceiling, return air grilles are designed to extract air from a room to be further conditioned, working in the opposite way to diffusers which supply conditioned air. The hinged design allows easy removing of the filter for cleaning.

MULTI DIRECTIONAL SQUARE DIFFUSERS

Multi directional diffusers allow 4 way air flow, with different finishes and colours available to suit the architectural style of the building. There are also models with four separate quadrants where louvers can be rotated to distribute air in the same direction. Multi directional diffusers are used with challenging room shapes or sizes to distribute airflow evenly.
