I know all this Jeff, I do service the minisplits as well as install them, and I have built a number of 2 to 5 ton units (ground and air) and have worked with a couple of larger manufacturers and seen their test rigs, so I know what they go through to build and test them.
That said, there are more ways to build a HP than the traditional TXV or cap tube. I'm not going to measure SH with the one I want to build next, it is run with a subcooling valve which is only concerned with single phase liquid temp, not trying to keep a constant SH.
Theoretically, all that should be needed is one thermister on a liquid line and the proper PID to control it.
