What is an aircon diffuser?

via GIPHY

Essentially, an air con diffuser directs and controls airflow in an air conditioner. Air conditioner diffusers are a critical component in a heating, ventilation or air conditioning unit. In ducted air conditioning, the diffuser delivers air to each zoned area.

Air con diffusers can be purchased in a variety of shapes, including square, circular or rectangular. They can be constructed of plastic, aluminium, metal, stainless, timber or cast iron. Diffusers also come in a number of configurations, such as swirl diffusers and slot diffusers.

Are an air con diffuser and an air conditioning linear slot diffuser the same?

Yes. A linear slot diffuser is a superior, modern and flexible type of air con diffuser that features a long, narrow design. It can be used to direct air in multiple directions. This special shape makes it easy for builders to fit the air con diffuser into a tight space and helps to conceal the diffuser from view for a more aesthetically pleasing design.

Air conditioner diffuser sizing

The size of the aircon diffuser is the diameter of the neck to which the flexible duct is connected. The air con diffuser sizing is determined by:

  • The area to be cooled/heated
  • The dimensions of the area length and width
  • The aesthetics of the space
  • The height of the ceiling
  • Larger diffusers/ducts move more air with less static. Static is resistance to the airflow.
  • Undersized diffusers will restrict airflow and create noise. Oversized diffusers can look out of place.
  • Correct sizing is important.

Area                       Ceiling Height         Diffuser size(dia.)
Up to 12 sqm          2.4 &#; 2.7m                200mm
Up to 12 sqm          3m                            250mm
Up to 20 sqm          2.4m &#; 2.7m             250mm
Up to 20 sqm          3m                            300mm
Over 20 sqm                                           multiple diffusers

For example, an average-sized bedroom is approximately 3 metres x 3 metres. For this size of room, we recommend a 200mm round diffuser.

Diffuser layout

Aircon diffusers for small rooms

Bedroom: Position the air con diffuser at the end of the bed
Study: Position the air conditioner diffuser in the centre
Ensuite: Position the air con diffuser in the centre but away a source of steam, such as the shower

For more information, please visit cleanroom door.

The ceiling is the most preferred place to install diffusers with a horizontal airflow.

Large rooms/areas

A round air con diffuser will spread cool air approximately 3 metres. If the room is longer than 5 metres, we recommend using multiple diffusers, spaced up to 6 metres apart and up to 3 metres from the wall.

Ducted air conditioning will feel softer when the air is coming from many directions. Therefore, 2 smaller diffusers will provide softer air conditioning than 1 large diffuser. For example, a living room 6 metres long x 4 metres wide with a 2.7 metres ceiling.

Locate one 200 millimetre diffusers, 2 metres from the longer wall and 2 metres from the shorter wall. Locate a second 200 millimetre diffuser, 2 metres from the wall at the other end of the room.

Practical considerations limiting the ideal location of aircon diffusers

  1. Lights, ceiling roses, skylights, ceiling fans
  2. Beams and ceiling joists
  3. Insufficient roof space

The final layout will be decided by the installer and the client.

An experienced air conditioning diffuser supplier can provide you with a suitable air diffuser to suit your requirements. To ask us a question about aircon diffusers, contact Crown Power today on 175 654 (Brisbane & Sunshine Coast) or 376 620 (Gold Coast).

What is the effective distance range of the acoustics diffuser?



In one local DIY studio video, he said that there are the effective distance range of the diffuser. It's no effective if the distance less than 2 meter from the speaker to the diffuser.

It's the new knowledge and interesting to me.

I tried to search the related information.

1.From this page.

Sound Diffuser Placement - How To Position A Sound Diffuser &#; Acoustic Fields

Today we're going to talk about ideal sound diffuser placement and where to position your sound diffuser for your particular room usage.



2.The classical video, all about diffusion from Ethan Winer
4:12, diffusers are usually placed at least 6~10 feet away from instrument, mic and listener. aim to make the artifacts too soft to notice.

Is there any research papers or reference materials for the diffuser effective distance?

Thanks a lot.

Hello,In one local DIY studio video, he said that there are the effective distance range of the diffuser.

A 250 cycle ray of energy is almost 5&#; long. If we divide the speed of sound by the frequency 250, we ~ 4 feet. If the well or trough depth is at a quarter wavelength then we need 12&#; of well depth at 250 Hz. With a four feet long ray of energy, we need at least 4&#; of distance from the diffuser to the listening position to hear the fill 250 cycles of energy. You actually need twice that distance. You need twice the distance so you achieve two full 4&#; oscillations.2.The classical video, all about diffusion from Ethan Winer4:12, diffusers are usually placed at least 6~10 feet away from instrument, mic and listener. aim to make the artifacts too soft to notice.Is there any research papers or reference materials for the diffuser effective distance?Thanks a lot.Meng
