The vortex unit uses compressed air from a shop compressor, which blows through a specially designed tube, making the air spin around inside at high speed. The heavier (colder) air molecules go to the outside of the tube and the light (hot) air molecules go into the center of the stream ..... exiting from the tube at the opposite end of the cold air molecules. So you get hot air coming out of one end of the tube and cold air coming out of the other end. The cold air can then be sent into a working man's specially-designed suit (like a space suit).

If you ever worked with a cream separator, you'll probably understand the principle. Heavier milk flies to the outside of the centrifuge and the lighter cream moves to the inside. The two go through their own channels of holes in the disks and come out at 2 different places.
