(3rd paragraph contains the question)
I hope this is in the right forum, I didn't see a differen't one would apply. I'll start by saying I'm not an HVAC technician, nor do I pretend to be one. I have family in the business, and curiosity get's the better of me, so I'm learning just for fun.
In my attempts to learn, I have read numerous websites, looked at charts, and talked to people in the business. I understand the electronics side of HVAC, it's the refrigerant side that leaves me a little confused at times.
So, I drew up a diagram, in hopes of helping myself better understand. What I would like from the group, is to look at my diagram, and tell me if I'm dead wrong, or close. Feel free to correct anything about the diagram.
