Looks to me like conventional refrigerants require too high a pressure for such a simple machine to work. See web site for picture, etc. Anyone have a scientific as opposed to emotional thought on the subject?

[shezza]

Cool!!

i am going to look at their website but it appears to be a centrifugal chiller of which there are many in operation. I haven't had a chance to look at it thoroughly yet though

[mrsmith]

Here's a link to a diagram of it: HERE.

Time will tell if it is practical, at least it doesn't overturn any physics laws.

[Fzob]

Fascinating concept.

Without giving it much thought, I believe it will certainly work. The real question is what are the ton's / HP. I see nothing to indicate that this device would make any signifcant improvements in that area. Although the elimination of a conventional compressor is a majors plus.

"It's really a pioneering invention," Perkowski said. "But inventions are generally the enemy of ideas in production. It might be received hostilely by industry leaders."

This is the sentence I knew I'd find. The old "there is a conspiracy against us excuse." It has scam written all over it.

[sit-rep]

I agree with you and do not understand the cooling end of the deal.

Gas is compressed then released through an orifice or simliar release mech. How can this work if the centrifuge is not spinning fast enough...or is it?

hmmmmmm...

In Oklahoma summer without air conditioning would be miserable for most.

Having lived most of my life in Oklahoma City, Stillwater, Norman, and
small-town Oklahoma...
I can honestly say the heat, humidity, and length of an Oklahoma summer can sufficiently
denature brain proteins to make you believe anything.

I don't know enough engineering/thermodymanics to judge this new-concept machine.
But if it brings down the cost of air-conditioning/refrigeration...I'm all for it!

[nightdriver]

Fine. Let's see one work. The illustration suggests a reverse Rankine cycle (like a freon unit) using a working fluid that must go through a phase change. As is noted in other posts, it looks like there is not nearly enough head developed to compress a gas to its saturation pressure by spinning it in an enclosed vessel. If it did condense, it would remain in the tubing at the larger radius as there is nothing to force it back "uphill" toward the expansion valve/orifice at the smaller radius of rotation.

The end result of the device in the illustration would be stagnation - no flow through the tubing at all. Sorry.

[Lazamataz]

I like perpetual motion machines. They are so cool.

Thermoacustics are the wave of the future. Only 3 moving parts, the acoustic driver, helium-argon gas,(in a hermeticly sealed unit) and a evaporator and condenser cooling fan in the 1/2 HP per ton range. Photovoltaic operation will be very do-able. Check out Cool Sound Industries I think they have the lead in this area, even though their ozone hole page is pure propaganda.

If I were building a new home or business right now, I'd go with a concentrated solar heat-Servel-ground loop system. The name of the company that makes this system is on the tip of my brain, ATM.

I've always thought that Tesla's turbine would make an excellent refrigerant compressor for continuous, or near continuous duty applications.

Bump for later read.

"...Anyone have a scientific as opposed to emotional thought on the subject?..."

Yes, I do, John. Have a wonderful and Merry Christmas, old friend!

Oh, and don't buy any stock in this guys' Company, or you will once again prove the old adage that: "A fool and his money were lucky to get together in the first place!"

The Laws of Physics and Thermodynamics are pretty much in place. Unless you see someone walking around with 'Cold-Fusion' dripping out of their pockets, I think the Laws will still be in effect.

They are fun to read, though...Stay well.....FRegards

I would think his methods would be hard pressed to exceed more than a couple thousand BTU of transfer, if that. BY the time he makes mods to improve the pressures he might as well get a high eff. heat pump at the dealership. I prefer Trane.

[Leroy S. Mort]

Kidwell has been working on the idea behind the Kelix since 1972, but it is still in the early stages of development.

At that rate, my great-grandkids should see some considerable savings on their cooling bills.

[techcor]

Vortex technology has been around for some time and can sort cold air from hot (or separate chemicals) but see Post #2 by kirbyj. It has parts that require energy, and is unlikely to be a huge improvement. Though it might offer some improvement.

If your interested in refrigeration, have you checked out Thermal accoustic stirling enginges? Pretty cool stuff.
