134A disappearing

[knotbuggin]

I have a carrier 30GXR135-AK641HL I had To add oil and A lot of Gas But ther is no visable signs of oil leakage and have used a leak detector everwhere . Anyone else have this or Ideas .

No oil ?

Should be some leak indication. Check the evaporater relief valves ? Motor terminals ?

[Nuclrchiller]

Tube leak ?

[knotbuggin]

No oil anywhere ,how do you detect 134a in your chill water .I did water sample for Chims today didnt see any oil and put a detector above water nothing .

Lets start by asking how much oil and refrigerant did you put in?

[knotbuggin]

40 lbs and 1/2 gal of oil

Why did you have to add the refrigerant and oil ?

[maxster]

shut the chiller down,isolate the chilled/condenser water and drain th barrels zero out then shut the drain cocks and cap them...next day see which one has pressure.it and the oil is going someplace.

this chiller ever have an Eddy Current test done, if not I reccomend.

Also if you want to pinpoint a leaking tube and if both ends are simple enough to get open:
-valve it out and drain barrels
-take one end off and check for milked oil in tubes(it sometimes gets you in the area)
-you can put a fan on it to dry it out or blow tubes out with air to help drain water
-got to craft store and but enough corks to plug the tubes on one side of barrel
-start sweeping the open side of barrel with leak detector.
-since one end is plugged it will push refrigerant towards you
-if you got the tubes decently dry you can insert leak detector into tubes a little bit to verify a tube (paint marker close by when you catch one is handy)
-put a cork in that tube to completely block it and if it pops the cork after sitting you have a winner.

****like previously said you need an eddy current and before you get one... Don't forget to brush

Also to add ...
I would start with the condenser. Unless you have reason to believe the evaporator got a little too cold.

Fix your leaks I doubt you have a cooler leak.

Sorry I just woke up from a nap on a HX machine.
I wouldn't go through all that on a GX. I would check it four more times with two or three different leak testers and methods before you followed my steps. If you still suspect a barrel pressure test like a previous poster said.
