Take a CO2 cartridge and poke a hole in it, let the gas out really fast and they frost up. My theory is rusty but I think some dude named Pascal had things to say about pressure vessels. Now it might be that the CO2 stream isn't colder, but something is radiant to get the frost.

Otoh, perhaps you mean to say that compression could occur without a major heat rise. No practical expertise there, I have no reason to compress CO2
