Awesome diagram. Thank you. I think I understand what your saying now.
As I see it the compressor and reversing valve will be right beside the house. Then the copper 3/4 lines that go to the manifold will go straight down 6+ feet into the ground out to the manifold under water. So I really don't have a choice as to where I put the txv on the outside. Therefore both lines will have to handle the low pressure vapor-liquid-oil froth.Is 3/4 enough to handle that? 7/8 copper wasn't too much more expensive.
"the Active Charge Control and Liquid Flow Control" is a quote from the artical above. The TXV is the Liquid Flow Control. What is the Active Charge Control?
