You probably wont see them, i have no thermometer for that kind of stuff and there are no 2nd hand units in Poland, new ones cost 350+ $Quote:

And now, about all the problems.....
1. Changing oil in rotary A/C compressors is... A PAIN IN THE ASS! You cant flip them and drain the oil, noooooooo, i had to drill a hole in the top of each of my compressors.... using a dremel (my best friend) and a mill bit.... Now i flipped them upside down to drain the oil:

Now the oil flowed...:

Something you should know.... when i tried to drain the oil through the suction line... i got only 50-70ml from each compressor.... by drilling a hole.... 350ml from the tecumesh and 250 from the sanyo...
Now as aenigma adviced... i brazed the compressor tops. First i shut the holes with a MIG welder, polished the surface and brazed it:

As you noticed... the brazing on the sanyo kompressor is much worse beacause it was the first compressor and i didnt remember where was the hole....
Now, after i got rid of my problems... i decided to start "dry assembling" it...:

The system was supposed to be so beautifull.... Small, compact, nicelly made... And at last i got a new condenser... brand new...

But nooooooooooooooo, my life cant be so easy.... A brand new condenser leaked so hard i could hear the hiss and there was a nice cloud of test R290... I was so angry i didnt know what to do ...
Right now im making AGAIN the whole system... i hope that at the 6 or 7th attempt FINNALY there wont be any leaks.... i would rather see the system blow up, annihilate itself than a knother leak...
As far as it goes for leaks.... Thanks to my Dad i have a new weapon.... a hydrocarbon detector... that nasty little toy smells PPM of hydrocarbons like... propane. So now i can fill the system up with propane a little and all leaks can be sniffed out... like with a dog... Too bad i cant teach my dog to look for leaks...
berkut
nuts u are , ohh yes , nuts :D
looking good mate
You must have one of the coolest Dads in the world!
Yes i have ;] My Dad doesent give me any money for hardware but he loves my projects (you should see his face when i told him i want to make a gas turbine, the next day i had a turbocharger to play with :D)Quote:

Now im working on my baby, ill be buying more parts on monday, soleneoid valves, shrader valves etc., R23 and so on.
If ill finish my cascade before a overclockers meeting in Poland its very possible that ill have sponsorship from Intel.... And so on ;]
damn... thats sounds nice :)
Do you go to like uni over there?
we call it "liceum" - in the us it would be... high school ? 8 clases of base school, 4 of "high" and later studying ... i dont know the proper terminologies. Im in the 4th class of "high school", 18 yrs old
I hope you will get a grip on those stupid leaks.
Would be fun to see this up and running :)
Well.... im so close... its finished, gotta adjust 1 little detail and she's 100% rdy
##d Damn its huge!!!
Why don't do the pics in early parts of the thread not work?
Edit for content.
OMG you are crazy! I would have lost my mind long before getting it working. Awesome wor there Berkut:D
Im about to abandon the idea of using a injector againt converting a 00X TXV orifice to a hand adjusteble valve.
The only problem is very percise brazing but its simple to make
Converting the TEV itself seems a lot easier. All you have to do is move the membrane. I'd say that cutting off the bulb and putting a manual pressure onto it would work. This gives you a wide open orifice at high evaporator pressures for a quik pulldown, and an almost shut orifice when the evap is at temperature.
you could take a txv cut the bulb off and use a notrogen pressure regulator to adj the flow rate by increasing the pressure on the diaphfam. Or you use a PEV which is a txv with a adjusting stem and a balance spring.
Ekhm...
I already have a TXV orifice and i simply want to see if this can be done easylly
I know i can operate a TXV that way but:
-No fun
-I dont have 75$ for a new TXV
chilly1 - probably YGPM in a few days ;]
why does the compressor in AC unit looks different from that in the refrigerator? can they be exchanged?
Woah. I only have a very very basic understanding of what you are doing, but I'm impressed.
However I'm now totally confused by those last few pics. I don't see how it fits in with the previous stuff in the thread. Probably not helped by the fact I can't see all the pictures.
Server problems or they might have erased realy old pics..... donnoQuote:

EDIT content.
Look like your going all out.
So any updates or have u just given up and smashed it like i would have by now.....after this many months the only way i would b able to do something like this is if it would take about a month....
ANY WAY MAN GREAT WORK!!
the compressors are all the same, there's like 3 diff compressors i think, i don't know their differenceQuote:

refer to #7 floor: this guy's room is real messy
back from the dead...
Haha holy thread revival. Is this a new record?
