And I thought propane was considered too high pressure for most uses (thus the isobutane mixed in with the propane in Envirosafe, etc).
Propane's about like R22. Not 'too high' at all in a system designed for it, but 'too high' for one designed for R12.
CO2? Now that's a different story. I'm sure that the CO2 proposal is a big STFU to the enviro-weenies. Yeah, it's technically difficult, but using the "greenhouse gas" directly (and make sure it's gotten via atmospheric extraction) will cut them off at the knees. Of course, if it's only 10% as efficient as R12 (guessing) where is the other 90% of input power going to come from? It's never about science. R12 was about science, nothing since then has been. More like Political Poker: "I'll see your black man, and raise you a woman." Hey, they both look great in a suit. Ugh. Ammonia is cheap and highly effective. Environmentally friendly too, it's used as fertilizer. Just a tiny bit dangerous, though! Still, it's used in RV refrigerators and nobody seems to have a problem with it there. They're also full of nasty Hydrogen, too. Hey, if they want us to treat refrigerant like it's poisonous, never leaking or dumping a bit, why not use something that actually _is_ poisonous, yet environmentally friendly? Ammonia is starting to sound more and more perfect to me!
Liquid CO2 has, IIRC, about 700-900psi vapor pressure at common temps. My liquid CO2 vessels are rated at 1800psi or more.
