Chart for the "whys of conditions?

[frankiee]

I am looking for a simple chart on the conditions and hows and whys of the results.
For instance:
TEV valve too restrictive. Super heat goes up because there is more vapor in the evaporator and more sensible heat transfer and less latent heat transfer.(I think that's right)
I am in school yet and and still trying to get it straight in my head.:confused:
It is a marine engineering school and refrigeration is just a component and we dont seem to have many resources.
Does such a "chart" exist.
Thanks

These charts excists but I think you're using already a much better technique right now: trying to understand why something happens and what the consequences are of this.
This is far better then using charts.
Your avatar is a log/p Chart and if you understand this completely and can use it in a real life situation, then you can solve many practical problems.

On your chart, a too small TEV, what will it do you think?

But I will try to find them for you: I have some from Danfoss but theyr're in Dutch.
I will look but in the meantime, others will perhaps post some helpfull information for you.

Download these documents and read them - they explain the TEV operation in great detail, even the answer you are looking for :) http://www.sporlan.com/tevs.shtm

HI Josip,

That was a very good site. Thank you for sharing this.

It has to be said that Danfoss ceertainly do invest some time in their presentations.
