AC condenser repair
 

The AC broke in my John Deere. AC is needed a bit more in a tractor
cause you get A LOT of heat off the machine, the cab is all glass, and
one little window to open. Easily 20 degrees over outside.

My neighbor is an HVAC tech. We found a hole in the condenser caused
the failure. First braze attempt still had a small leak. The second
attempt, the braze slumped into the line and party blocked it. Now I'm
FUBAR.

Somehow, I need to cut this braze out and weld a patch over it. Or
pull a 180 U off of one end and bypass this run. It is the first top
run on the condenser. Anyone successfully done either operation?

I looked for generic replacements. John Deere isn't listed. No joy
trying to find one based on length and width. For those that don't
know, John Deere selected their tractor color because of the amount of
green you need to buy a part. Anybody know of a place that will supply
a condenser that fits within a certain height and width? I do know a
machinist that can build a bracket.

I'd suggest to contact some refrigeration or HVAC firms near
you. Sometimes folks take out a "condensing unit" which
still contains a good condensor. I'm not sure what the line
sizes are, or the size of the condensor you need. But,
that's an idea. Very often the take out units are dumped in
a pile, and later taken to the metals recycling yard.

Not sure about skipping one loop of the condensor, I've
never heard of anyone doing such a thing.

Best of luck, it sounds urgent and needed. I don't have a
condensor to offer you, wish I did. You may be able to use
one out of window AC.

Have your hvac tech friend put a small pressure in the condenser (1-2
psi-where goggles) and heat. It may push out the slump. Then you can remove
pressure and braze again. You can bypass any line in a condenser provided
you look closely an verify all other passes are in the loop. However you
will not have as much condenser as you once had. This may mean you clean the
condenser or filter more often or it don't cool as well. If it is copper you
can buy fittings to fabricate a 180 degree bend if you have room for it. The
idea is to salvage as much condenser as possible. I have messed up many
condensers trying to repair them and most of the time have been able to
remove the slump of solder and try again. If copper........try dynaflow
(available hvac/r distributors) it fills nicely. I have filled 1/4" holes by
filling in around the hole........letting it cool ......fill some more etc
until it is fixed. Blow compressed air or something thru, when you are
finished to verify you did not plug it.
Good Luck

The Surplus Center often has them, At the moment it appears they only
have one size in stock, probably not large enough:

The braze you used probably had too high a melting point. You should
use a phoscop or similar brazing rod that has a lower melting point than
copper. Silver solder would work too. There are also epoxy compounds
that are used but I have no experience with them. I do only industrial
chillers and coolers on machine tools. I fixed a leak in a condenser
the other week after a refrigeration guy couldn't find it.
When you braze the leak you should purge the system with dry nitrogen to
get all the freon gas out of the system or you will make hydrofloric
acid when it breaks down from the heat of the brazing. The acid will
cause premature failure of the system.
Most guys don't take the trouble to do the job right. It also gets them
more work in the future.

HVAC condensers are not magic. You can replace the whole core if
necessary, so long as the new core is the same size (heat transfer fin
area) or perhaps a little bigger that the original, and the tubing size
is a reasonable match.

I assume that the tubes are copper. The usual braze filler is
phosphorus copper, which is self fluxing on copper.

Probably the best source of a core is the automobile aftermarket. Do
the research in the junkyard, then buy a new core for installation.

The easy way is to make a repair sleeve out of the same material and
slide it into place then silver solder it in place by sweating the
joints.Just like doing copper pipe joins.

Since it's the outer tube I would probably do it even easier. Take a
Dremel type tool and cut out one side of the tube where the braze
slumped. Remove ONLY the slumped area and clean the tube up good. Make a
patch that will cover the hole with a slight overlap.
Clamp the patch in place and flow the solder around it.

The few patches I've done, mostly cut a piece of copper to
shape, to patch. And braze that on. The "circle" and then
build the igloo technique, good idea.

Most likely, no.

--he was still the villiage idiot over at alt.hvac last time that I checked.

But if you can't simply hang your coil in the water ( as in houseboat ) (
DX ) then the easiest way is to counterflow chill--a refrigerant loop of
copper that's been shoved inside of a coil of black poly pipe to serve as an
outer jacket that you can pump seawater through in the opposite direction,
fairly easily done with r134 automotive stuff from the wrecking yard as long
as you can braze and /or form tubing into a flare.
