Just a continuation from a post that is a few pages old... (Great discussion, by the way)

I heard that R-134a was being phased out. Anyone else hear that rumor? If true, now would not be the time to convert to R-134a (in answer to that earlier posting).

I wish they would go back to R12 lol,,only because I have many many tanks of it and some R22 as well,, we used to do refrigeration but when they started changing everything we decided to get out,, we do have a pumpdown unit and all the toys needed to do the work yet, but now we just do appliances,,,and a lil heating...Jim

actually, it is just in the very beginning stages of being phased out in cars. in the future cars will use carbon dioxide as a refrigerent. however, it operates at over 1000 PSI and will not be a drop in replacement for systems that use any other refrigerent. so if you have an r-12 system you want to convert to freeze 12 or r-134a, go ahead and do it. it wouldn't be a bad idea to stock up on 134a, because in a couple years you'll prbably need a license to buy it, just like r-12

What I read says the new CO2 automotive AC units will be electric powered and sealed like a household window AC,No hoses or compressor shaft seals to leak. The AC,radiator fan,power steering and power brakes will all be driven by the cars 48V DC electrical system. They are supposed to be on the market within a few years.

Does anybody remember what happened to the air conditioner that was invented by a guy about 30 (or more) years ago? It was supposed to cool without any chemicals. I think it was written up in Popular Mechanics or Science. Maybe it went the way of the 100mpg carb.

I have a dim memory of that story. I seem to remember that it used some type of scroll compressor and used air for the working fluid. I suspect it could never pump enough heat to do the job with only compressing and expanding of the working fluid(air)without it going through a phase change. Most conventional AC systems depend on a working fluid that can go through a phase change at fairly low pressure( gas compressed to liquid-liquid expanded to gas) as many times more heat must be absorbed or released to go through a phase change.

It was probably referring to the soild state units now used in the little cooler refridgerators and to cool some computer chips. They work but are energy hogs compared to how much cool you get. I can't remember what they are called....

Boy Ill bet those 48V batteries will be cheap too:) Dealers will make a lot of money before the aftermarket outfits catch up. Think I will buy another car just before those types come out and maybe things will be settled down by the time I need another one.
