hi dave,
vortex tube is an old thing and works on a totaly different princip, yet its widly used especialy on milling machines for cooling the drill bits.
very expensive to run.

Re: Thermoacoustic Refrigeration
I once bought a small Vortex tube for testing but you need a damn big compressor before it works fine.
There were some different ofifices in it.

Re: Thermoacoustic Refrigeration
first time iv come across all these other methods of cooling, and its pretty amazing...any others out there ?
do u guys reckon this is the future ? to create a method of cooling withough using refrigerant ? or is it a race ....either that...or until someone comes up with a refrigerant thats totally safe to use...
