Chart for the "whys of conditions?
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.
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

Re: Chart for the "whys of conditions?
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.It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

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

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