Hi,

For those of you had been following my nightmare install of a 410a/TXV/Scroll heat pump system a few months back, a tech from the installing company is finally coming back Monday to do a thorough eval. Unfortunately, I suspect I will be told "Oh, that's normal" in instances where things are definitely NOT normal. I think I can defend most things, but there is one area I would appreciate some experts help here on the forum...

In cooling mode the smaller line at the air handler has something going on that I am all but certain is not normal however I'd like to get some opinions here on how to counteract things if I'm told "Oh, that's normal". The line has so much going on inside it that it is actually vibrating a lot. It feels like a constant flow of intermixing gas and liquid inside. If I understand correctly, this is NOT normal and not how things should be operating (there should either be all gas or all liquid, I forget which). Also, in case this might be related, sometimes that line is very cold and other times it is very warm (seems to follow the outside temps oddly enough).

I am hoping the above and other issues my system is having are all just charge related, but we'll find out Monday....

i haven't looked for your other posts, but it sounds like it wasn't charged properly.

Just thought I'd warn you.

The funny thing is I think you are serious.:gah:

Sonic,

You have a TXV metering system. The TXV requires a full stream of liquid to function properly. If I remember correctly, your problems were during the colder weather. Your system was probably not charged correctly and may need to be charge adjusted. A competent tech should have no problem doing that.

I am.

Ask him to check the subcooling and then how he came up with the correct subcooling temp. Then after the subcooling is correct have him check the superheat to check if the TXV is metering correctly. Some manufacturers have it stamped right on the data plate at the condensor.

This definition here works for me http://www.urbandictionary.com/define.php?term=trolling

Sonic had a big mess with the use of his old line set. It was submerged in water in a flooded chase so the charge was always off and his refrigerant was flashing in the lines causing them to vibrate and make noise, not to mention he himself had to mount the txv.

Plus, the original installer apparently did not braze with N2.

*sigh*

Anyone else tired of this system?

Trust me, nobody is more tired of this system than me, and I OWN the thing. :gah:

 

[SonicExplorer]

Thanks for explaining .... solid stream of liquid....that's right... I had forgotten. So I'm correct then, there should not be any vibrating/rough stuff going on inside the line that feels like gas flashing & mixing with the liquid, right? I am willing to bet the tech is still going to say "Oh, that's normal, 410a systems are under lots of pressure." That's an example of the kind of BS excuse the techs previously gave for legitimate issues. I might as well have hired a parrot with guages.

In the last few months I have felt and listened to over two dozen systems, mostly 410a. From Lennox to Trane to Carrier to Bryant, you name it. And NOT ONE OF THEM had the kind vibration and weird stuff with the lines going on that mine does.

I'd be interested in hearing any suggestions from you guys as to what to say to the tech if he tries to tell me it's normal...

Don't say anything. Just find a technician who understands refrigeration theory and knows how to apply it.
