Noob questions

Well, there's one thing I've been wondering. What does it mean by pressure? I mean, in saying this, is that why is the pressure calculated for the condenser and evaperator?

And how do you determine what refrigerants would work with each other to make dual stages, or triple stages?

Thx in advance.

bump.

I dont mean to be rude, please read the stickies, in particular the one titled "3 new guides"

The 3 new guides tell you how to basically build one. I'm trying to learn how one knows that two refrigerants would work as a dual stage. Unless it doesn't really matter...

Thx for the help so far.

I agree above. Read more.....but.................

Are you talking about blending 2 gases together or what gases to use on a 2-stage cascade (i guess your using "dual" to describe a cascade).

You need to be more clear on the Q.

I'm asking what gases you could use in a 2 stage, or 3 stage cascade and how you could usually determine that.
