Hey Jeff,
I think Xringer is going to take it. He lives in the town next to me. He helped me with it when I had a problem with the thermostat. Otherwise I would have been happy to give it to you.

I wasn't referring to me specifically... Good to know it isn't going into a landfill somewhere. Xringer is pretty handy, I'm confident if he takes it, it will be working again shortly.

I'm lucky to be living in the next town over from a generous man!
I've got the tools and the parts to do a leak repair.. (I've done one in my life).

But, all I have for refrigerant is R410A.. And maybe a can of R134A..
Isn't there some substitute for R22? That doesn't cause global warming?

R290 or R1270 will do it. For nonflammable gases, others have used air duster successfully (can't remember what R number it is). Most everything nonflammable has high ozone depleting or global warming potential.

R152A LOVE the stuff! But it is more of a cheap replacement for R134A, http://www.sae.org/events/aars/prese.../manhoekim.pdf
I would like to see it compared to R22 though.

Flammability Properties of R152a versus Hydrocarbons

"A comparison of literature values of the flammability properties of R152a to those of hydrocarbon gases such as methane (R50), ethane (R170), propane (R290) and butane (R600) revealed some differences in ignition limits, ignition temperature and minimum ignition energy. However the flammability properties and specifically the pressure rise of the combustion process are not so much different to approve R152a for automotive air conditioning without further detailed investigations covering cabin, engine compartment and servicing area.

The combustion gas of R152a contains harmful hydrogen fluoride. Risk assessments have to take this fact into consideration."


https://en.wikipedia.org/wiki/Hydrog...Health_effects

Well, heck! May as well use R-290!

That's the spirit! With most likely under 4 ounces in the unit, the risk is pretty minimal.

QUOTE=Geo NR Gee;50478]Here is the answer from AirGenerate Support (Jan, 2012) when I inquired how much refrigerant went into the system.



The AIrTap A7 takes 8.8oz of Freon.

Not yet. Now that the holiday is over, I'll go fetch it soon..

Since the long HX tube is broken, maybe I could set it up to be a recovery pump.?.
I can't do a pump-down on the broken Sanyo,(w/o power to the compressor) so recovery is a must..
