Assuming you are in the USA, and assuming it is a 115 or 230 VAC air
conditioner that runs off the AC power line or AC genset, that would
be the same R-22 used at home or in your fridge. The only difference
between a boat air conditioner and a window unit is the boat has a
water cooled condenser and costs 5 times as much. The window unit has
an air cooled condenser. Both of them use R-22, the standard
refridgerant for enclosed, all metal units without hoses.

Newer ones R134....older R22. R12 is a refrigeration....

Well actually I meant R-12 like my 1992 Mazda uses. I think R-22 is a type
of "freon" used before R134 came around in aviation A/C systems. JC

Marineaire, probably the largest player in air conditioning on boats
over 30 feet, currently uses R22. I've seen R134a in refrigeration
units (the Sea Frost we took around the world was R134a), but not in
air con.

Jim,

R134A is currently used for the Air Conditioning in most vehicles sold in
the USA after 1996. I have a 1998 GMC Suburban, a 1998 Honda Accord, and
a 1999 Freightliner which all have R134A systems.

OTOH, my home ACs are Carriers, and they are R22 systems. Carrier also makes
a "Puron" system which doesn't use R22.

Later,

Don W.

Thanks, Don. I should have said "in boats", but the fact is, I didn't
have a clue what's used in cars.

What difference does it make what refrigerant your boat A/C uses? (I would
bet R22)

It has to do with the range of characteristic of a given
refrigerant....how much pressure it takes to condense at what
temps...what is the temp of evaporation at what pressure....how much
heat change during change of phases from liquid to gas and
back...blah, blah, blah.

First off you can't buy R-12 or R-22 without a license. I would think that
if you had a license you would have test equipment and would be smart enough
to read the gauges to realize the system is R-12 or R-22. Double Duh...

Duh. Put R-12 in a system that uses R-22 and watch it blow up!

None of course. So go ahead and add what ever you have handy and let us know
how it works out.

Triple duh, it's not that hard to get R-12 or R-22 wthout a license. And
pressure gauges in and off themselves will not tell you what type of gas you
have in your system.
