superheat

[Josip]

Hi, BigJon3475

"Yes, but if the super heat is zero then you have mixture of liquid and vapour going out.
We must always have between 5-8°C super heat to ensure there is no liquid going into the compressor.
With cap tube it is not in our hands, this is way an accumulator is recommended for such application.

Hope this helps
Cheers"

All of my applications have an accumulator and I know how they work and I'm glad they are there :-).

With ammonia you can go as low as 2K...or 3,6R, because for superheat we use absolute temperature scales Kelvin or Rankine but without sign ° for degree.

Correct me if I'm wrong but isn't 5-8°C=41°F-46.4°F.. If that's correct I have been way off...

Correct and not

In terms of temperature level/value correct: 5°C=41°F, and 8°C=46.4°F,

but in terms of superheat wrong because:

due to different division on the scale we can say 1°C=1,8°F thus we have superheat of 5°C=9°F or 8°C=14.4°Fabove evaporating temperature meaning the difference and not a value


English is not my mother tongue but I hope this is kinda good explanation...
