R-22 is an HCFC, the new gasses are HFC's.

R-22 has just recently been phased out. it is the chlorine molecule that was supposedly the "problem"
CFC's and HCFC's were heavier than air.
both are non-toxic and R-12 in particular, was incredibly non-toxic.
(asthma inhalant propellent)

yes, it is the biennial oscillation that creates the "ozone hole"
ozone is toxic and is used as a disinfectant and also for water treatment. as a flocculant

the refrigeration oil is the main difference between the old and the new gasses. refrigerants, "Freon" I call them gasses and freon is not a substance, it is a brand name. DuPont

it was the chlorine molecule that was doing the most oil return. (other than velocity) HFC's have oil return problems with mineral oil. HFC's have to use POE (Polyol Ester) it has high dielectric strength, but is also highly hygroscopic.

R-410A or "puron" is the new darling. for whatever reason, it has been shunned until now for commercial high temp refrigeration. (A/C)
it has no medium or low temp applications that I know of.

I could go on and on about the subject but was really just intending to give you more ammo, (information)

peace and rock on brother!

I am not sure if tamckissick is a disinfo-agent, a troll or just confused.

we talked on the phone once when he was pretending to help me with an analog to digital proportional control retrofit.

he was not able to help. he was a pretender.
I was not going to comment on this post. unlike other folks around here, I really am what I infer that I am.
