Old window AC unit....worth keeping?

[TheDude]

I can't find any markings clear enough to be read. It runs and gets pretty cold. Is it OK for a simple chiller? Or boat anchor? :D

Nice one...

The condenser is heavylly corroded :\ I would try to cut out that part, its easy even with a wood saw and play a little with brazing ;] Or you can sand it but i didnt ever try such thing and i dont know if it wont sand of all those fins ;\

Whats that fluffy thing on the left side of the compressor ? :O

I think you should take the compressor out, seal all connections and sand it cause corrosion looks preety bad and we dont like it

Put some Navel Jelly on that bad boy, and see whats left. repaint what you can and take another look at it.

berkut.....was hoping someone would tell me....it's got a line runing thru it...hell if I know!

Yeah....That's exactly what I am going to do....it's pretty shot.

Keeper, Good idea! maybe I can find some markings on it at least.

Well it's worth playing around with.....my torch skills could use some practice and if I screw it up...well....how can I screw that up? LOL :D

..... Fluffy stuff is insulation. Take it to the car wash and give it
a bath. Back off a little bit when washing the condensor and
evaporator as the high pressure spray will bend the fins on those
fairly easy.
The local hardware store will have condensor cleaner in a
spray can. The condensor will clean up a lot.
That's a heavy duty looking A/C. Must be approx 10K BTU. And
looks to be 110V. I think 10K was about the limit without
going strictly 220V.
Good find. It would make an excellent chiller. Check out the
thread by runmc over at phase-change.com on the
chiller he built with the spray bars etc for the liquid. You'll
pick up some good idea's.

Luck.

Well i am quessing it is made of alumium like material and feals like a brush?right...lol;)

i cannt tell where it is going to or if it is going anywhere dude, but it is a cooler.it disapates the heat generated and helps cool the compressor i am guessing.

[TheDude]

Yeah...it's not insulation....it is "brush like" and does appear to be used to remove heat.
I don't know the BTUs but it is 110v as I plugged it in and ran it...runs very cold so it's charged and not leaking....yet. :D

Popcicle...thanks for the tip on runmc's thread...I'll check it out. :D

TheDude, could you make a shot of it from a different angle ? Is it connected to anything or has any valve on its end ??

It cant be a heatpipe cause it has 180* turns so no colant would come back...

[TheDude]

How's this angle? You can see the lines.

[berkut]

This pic is perfect ;]

I would say its a oil chiller, theres no other way, it cant chill any refrigerant unles theres a 2nd piston/rotor just for internal winding cooling purposes 8|

Anyway it begs for sanding and repainting :o

You plan to use it as a water chiller or going multiple evaps like bowman with his newest project ?

I'm not ready for something that ambitious....just a simple water chiller for WC rig. :D

[berkut]

:\ Too bad, but if bowman finds how much cap tube should be used it wouldnt be so hard for you to make such a system (+ bakers blocks etc.), just a matter of soldering/ brazing everything
