Can you see it

[Charley L. Bottger]

This is a 4 ton A-coil set up non adjustable expansion valve with external equalizer line IMO there is a engineering flaw in the design set up can you see it and would you have the intestinal fortitude to call it if you would have seen this.

BTW did you know the color of the sticker on the expansion valve denotes the type of freon the valve is designed for green=R-22

The odds of it ever happening are almost non-existing but if the expansion valve was visible and had a yellow sticker and the name plate data on the condensing unit stated R-22 would you have noticed this.

Come on guys this is basic refrigeration you are disappointing me, any HI worth his salt should be able to spot this problem.

Well, let me be the first to say that I don't have the foggiest idea and I don't work for salt so we're good to go deferring...but always willing to learn something.

The only thing I see is that the dynamic barometric overload compensator is positioned in such a way as to likely render it ineffective during a polyphase rendering occurance. It would certainly lose efficiency with that condition and I probably would have noted it in the report. I hope this doesn't disappoint you.

I saw that exact same thing, too. However, I thought that was too obvious for what he was looking for.

Just a guess... would it have something to do with unequal pressure. Possibly a lower amount of r-22 going into the second set of coils, based on the 'parallel' set up of the line.

Hi Mike that was really good LOL could not have stated it that well myself. I think it is just great that someone will just say I don't know.

Hi Larry I don't have any salt either. I am going somewhere with this just hang in there. This A-coil was out of my old furnace and I had to modified it to make it work back in 1991. For the Pic I un installed my modification what you are seeing is just the way it came from the factory.

I thought my second post would raise an eyebrow

10-4 chief, look forward to it.

Excessive corrosion, call out a HVAC guy to certify remaining life.

Is that blue and green thingy the flux-capacitor???

[Charley L. Bottger]

Ok guys I am going to finger the problem tell me why it would be wrong

So how/why did it get there Charley?
I's been operating like that?

Not yet Dave, let's see how long it takes for him to break and tell on himself

Oh, okay...............
