Dyson bladeless fan/turbine compressor building air cooling?

In summary: It's hard to tell if it would be quieter if the pump and ring were located remotely. No, it would not be quieter.

the Dyson bladless fan relies on forcing air out along one side of the rim of a ring, so drawing air from the other side of the ring to create more airflow

the household implementation of the fan uses an ordinary air compressor at the base to pump the air into the ring, and this creates a noise which is more prominent than that which is produced by the blades of a regular fan


does anyone know , if anyone has used the bladless fan in such a way as to have the compressor at a remote location, and the ring connected by high pressure air hoses to the compressor?

furthermore, for the pump/compressor, it needs to be able to have a high air flow rate, especially when it is supplying compressed air to many bladeless fans...would a design like the compressor stages of a jet turbine engine work well?


the idea is that it would compress the air, causing it to heat up... the hot compressed air would then pass through a radiator section where flowing air bypassed from the pump (somewhat like the bypass air from modern jet engines) will cool the air to near ambient temperatures... when the compressed air reaches the fans, the decompression will cause a temperature drop in the air, thus provide an air conditioning effect, in addition to supplying fresh air in the building and causing large amounts of air circulation due to the function of the bladless fan

Sure. We could also call those (not so) high pressure "hoses" ducts. Then instead of bypassed air for cooling we could use refrigerant. Lastly, instead of rings we'll use vents.

Anyway, I'd say you're exaggerating the "compressor" and its effects of heating and cooling.

You can get a lot of heating but it takes a lot of energy so is not efficient.

It is my understanding that what the Dyson has is much more accurately described as a centrifugal blower, not a compressor. It doesn't produce anywhere near the pressure of a compressor. A couple of inches of W.G. instead of many PSI. So there wouldn't be much cooling effect.

does the air flowing out of the bladeless fan create a lot of noise? it is normally hard to tell due to the noise of the blower in the base of the commercially available Dyson fans... so would situating the air pump remotely and connecting to the ring via hoses allow air to be circulated silently?

There is still a fan inside of the blower. It is basicly a gas/gas eductor.
Similar to a natural draft cooling tower you would fine on a nuke plant.

I've checked these things out. Much of the the noise is definitely coming from the outlet duct.

1. How does a Dyson bladeless fan work?

A Dyson bladeless fan uses a turbine compressor to create a powerful airflow. The air is drawn in through the base of the fan and accelerated through a narrow opening, creating a jet of air. This jet of air then passes through a channel that is surrounded by a ramp, which draws in additional air and amplifies the airflow. The result is a smooth and consistent stream of air that can be adjusted in speed and direction.

2. Is a Dyson bladeless fan more energy efficient than traditional fans?

Yes, a Dyson bladeless fan is more energy efficient than traditional fans. This is because the turbine compressor technology used in Dyson fans consumes less energy than traditional fan blades. In addition, the design of the Dyson fan allows for better air circulation, meaning the fan can be run at a lower speed while still providing the same level of cooling.

3. Can a Dyson bladeless fan cool an entire room?

While a Dyson bladeless fan can provide a strong and consistent airflow, it is not designed to cool an entire room like an air conditioning unit. However, it can effectively cool a small area or provide personal cooling for individuals in a room.

4. Are there any maintenance or cleaning requirements for a Dyson bladeless fan?

Like any other fan, a Dyson bladeless fan will accumulate dust and debris over time. However, the design of the fan makes it easy to clean. The fan can be disassembled and wiped down with a damp cloth, and the filter can be removed and washed. It is recommended to clean the fan every few weeks to maintain optimal performance.

5. Can a Dyson bladeless fan be used in conjunction with an air conditioning unit?

Yes, a Dyson bladeless fan can be used in conjunction with an air conditioning unit. In fact, using a Dyson fan with an air conditioner can help circulate the cool air more efficiently, reducing the need for the AC to run at a higher speed and saving energy. The fan can also be used alone during mild weather conditions, providing a more energy-efficient cooling option.
