20 deg. superheat, why? continue

[comfortmaster1]

It seems that my last tread is closed. Nevertheless, I owe some of you a response.

amickracing:
Thank you. However, could you give me an example of a situation where a 20 deg super heat would be fine?


mrbillpro:
I have not tried another temp gauge but i am confident that the suction line is 65 deg.
Among other things, the suction line is not condensating.
Also, your arguement for calculating Delta T seems to make more sense.
However, would that be called Delta Enthalphy?

What exactly is the problem? Did I miss something?

There is no real problem. I'm just curious.

Is that a 96,000 BTU furnace with a 5 ton blower on a 3 ton A/C

The system is 2yrs old. All original parts.

What would you like for it to be?

10 deg.


emoney1971:
It is a piston (fixed orifice) system.
I believe all you need to calculate superheat is suction pressure and suction line temperature.

Nothing wrong with 20 degree s/h. It's what I charge a non-txv system to, if there is no charging chart.Modern Refrig&A/C tells you this.

You would have to ask you compressor valves that question. :D

my guess if they could talk it would be it's a bad thing.

[kanderson]

just wanted to know if that's what it's supposed to be or is that wrong? all i know it's not cooling worth a sh*t and that's what the guy told us. i wish you dudes spoke english instead of hvac. lol

[beenthere]

Did he tell you why you didn't have any superheat at the compressor.

[smokin68]

0 superheat= very bad.....plain english. :D

Thanks Smokin you know me I always try a little humor in my posts if at all possible, but not good timing for me I guess. :D

[kanderson]

no, he didn't say alot to us, he was speaking to the maintenance guy here at the site. he wanted to know if the coil that was in there was the correct one, the guy told him it was a compatible. the a/c guy told him that it was installed incorrectly. the maintenance guy wouldn't let him fix it, he did it himself. the report shows 0 degrees superheat at the compressor. i'm very confused because the maintenance man is saying that there isn't anything wrong.

[beenthere]

If there wasn't anything wrong, it would be cooling your apartment.

If the maintainance guy installed it himself, he won't admit he did something wrong, and cost the complex money.

Keep calling and complaining about it.

I see. So if one is a former tech and he wishes not to register his credentials, he can not ask such questions here.

[jrbenny]

That's correct.

Thanks for your understanding.
