thanks so much for that reply. I'm sorry I must have missed the notification that you posted it, and then the anti-spam politeness means it doesn't send you another notification that others...
Sorry, I am probably restarting a thread that has been pounded into the ground a few times but the search function won't let me search TXV, because it has too few letters.
I'm building a couple...

what does your bro in law say. I'm thinking a piece of this in a piece of plastic is a piece of work - i.e. a ready made evaporator, no ....

tell your brother-in-law he can sleep soundly. I have yet to go postal over refrigeration. matter of fact I'd be glad to buy him a beer (as long as I can have one too). My intuition about...

So this is my idea in a coil format instead of long and straight. The thing I can't figure out is why do they want to put the...

that sounds backwards from what I was thinking in flow terms. Because the subcooled liquid is entering from the condensor, ergo that seems to me to be common flow direction.
It is, however,...

so the entering water sees the exiting R-22?

You're talking to a guy who is thinking from his H experience not his AC. So I'm imagining, probably incorrectly, that the obvious heat exchanger would be like an indirect hot water heater....

. . . few rubber bands, bailing twine and bent nails.
or should I just call you Macgyver. Just who I needed to meet.
So I found some braze plate stainless exchangers...

Maybe you could be the moderator. You've got the moniker for it. Ran out of characters so you couldn't get the "h" in. I hate it when that appens.
So I have a question for the...

or is that the kids?
I don't know what i've done to my computer. I don't see the avatar's, but whenever I log on from somebody elses computer I do. Oh wait, this is refrigeration help, not cyber...

I'm getting that sinking feeling, but never say die. If I can get a drawing of the evaporator to guide my approach so as not to hit anything I shouldn't, the one thought I have before going the full...
I'm not familiar with the unit but in terms of diagnosis I'm with berg2666. on the fans. Have you checked the start and running amps on each one. Don't know why it would be just in the overnight...

couldn't avoid a passing reference to having taken time off from refrigeration for a half hour this morning to post at my favorite law blog about Heller v. DC, but its back to Brian v. the chiller.
He will probably chime in, but if you search for threads that "jayguy" has posted on you could send him a PM. It wouldn't surprise me if he responds before you get around to that although it is...
Would have to calculate the gpm using pump specs. Maybe I work backwards by pressure drop. I don't have pressure readings at the chiller, but the supply lines are 2" and at the main pumps i have...
Andy, sorry it took me a full day to get back to this. I appreciate your thorough go through of the scenario I laid out. In particular then to correct the semantic of my discussion, e.g.:

from the thousand lbs. plus nitrogen flush but I already had all valves and other junk removed so I probably would have gone for it if I saw your post first. It was only piping so maybe I should have...

That might make a little sense to me given the age of the chiller. I do drain the chiller every year and I haven't been getting gruesome stuff out of it, but maybe unless I agitated or blew some...
My emperical low load results coordinate with the scenario you outline Quixote. If I don't mistake, Andy and Jorgas are arguing whether the low suction is enitrely TEV metering or to a degree posed...
Yes that is my understanding.
I haven't worked on hot gas bypass system. Is this a way of keeping the head from getting too high when the TEV is restricting flow?
PS -tried to...
Jogas, sorry we were posting around the same time so I would have brought in your comments as well.
This was my intuition, generally speaking, that aside from lower load because...
Sorry, when I'm balancing a long thread and several quotes I'm not sure how you get the effect that names the source of the quote. If I wasn't baked from several days in the sun swaping...
low load: low suction, low superheat, normal head ?
and on the condense no condense argument, I'm still waiting to hear if this was the biblical flood. Sounds like the result wasn't stable, was...

got several candidates
age - 18 years
dirty condensor but I would have thought that would have shown up in cooling performance rather than compressor failure.
crankcase heater was factory...
