New air con invention, but how does it work?

I'd imagine if its any good it will be a closely guarded secret. I'm a bit perplexed though, as nowhere does it say that all aircons use CFC containing chemicals, just that the ones we tend to suse for max efficiency do as we know exactly where they change state and absorb and give off the heat. I'd imagine you could use water if you did not want to get freezing temps. As for the spinning disc, Is this some kind of centrifugal fan type device? Brian

There a diagram of a piston compressing in a cylinder, talk of a pipe and a fan, but nothing adds up to a means to cool air.

If heat is removed from air, then somewhere that unwanted heat has to be disposed of - I don't see any sign of a disposal system, just in one end, out the other.

Talk of Dyson being involved.

YouTube is full of advertisements which use a version of the a similar story to sell glue/ torches/ polishing cloth/ …..

Seen that?

It would appear to be a minor new twist on an old heat engine.

Pretty much the same as when you pump up a bike tyre the air gets hot - allow it to cool somehow (unspecified method - it doesn't look like it has anything like enough heatsinking to be remotely useful).

Allow it to expand adiabatically into the room and it will cool. There might be something in it if the parameters are just right but it would need some very cunning external heat sink.

It will be another product like Dyson's blasted airblade hand driers that deafens everyone within 10m without drying your hands. After a couple on minutes most people give up and dry them on their shirt!

My money is on meta materials that can passively cool in direct sunlight as one of the eco friendly ways forward. They look like a mirror to visible and near IR but black in the thermal IR band at 300K.

My experience of hot-air hand-driers in public loos is that they are *all* much slower than a roller towel or paper towels. I'd say that Dyson's Airblade is better than the sort with a large 5 cm nozzle: maybe the higher speed of the air blows water off your hands as well as the warmth evaporating some of the water.

It provides a sort of explanation of the principle of operation, but the text reads as if it is a Google translation to English.

I think Martin Brown (below) may have an idea of how it works.

All I seem to get when following links is web pages titled Air Disk Cooling Technologies but are only are about digital money transfer advert.

I think I've seen the same on facebook where clicking any link about this "technology" is just clickbait for advertising.

ISTM that without a phase change, you'd have to shift an awful lot of air to make a difference, so the device would have to be very large.

I find that the air blades do work but most people don't seen to move their hands through the airflow to move any water down to the finger tips.

They do seem to work mostly by high air flow and a small amount of heat. I find them quite effective.

Yes, just move yer mitts up and down and they work quite well. Pretty obvious, really.

There is a bi of info here:

I'm wondering if they are using the Tesla turbine principle? To compress air and perhaps then act as a motor to expand the air.

I didn't think Tesla turbines were very efficient.

ask the Nips ....

I found that (and a couple of related) patent applications, I'm not really au fait with patent-speak, but phrases such as

"unity of invention is lacking"

or the cited documents "not considered to be of particular relevance" or "cannot be considered novel"

and "no required additional search fees were timely paid by the applicant"

don't sound great?

Obvious once you know. The first one I used was mounted high so I inserted my hands horizontally, which failed to turn it on.

The main issue with cooling systems is that you have to have a way to take the heat inside and put it outside.

Anything else is a "swamp cooler".
