HAHAHA, YOU an idiot? Yeah ok sure, and I'm running for president.
Awesome info and really what I'm looking for. Sure I can make this thing work well with fewest parts possible, but if I'm going to live here for I don't know how long, I want this to be something I designed to run the best it can.
Heck why not digital control of the metering device like a mini split. I would love to control the compressor, the water pump, and the txvs! But that just might be a dream......
Hard to find the ZPD so far but a couple of hits for the ZPS came up, all for 410a of course so I could either use 410a or just know I need a larger compressor to get the same btus out of propane.
Here as an article on the ZPD, I would be a cool project to try a solenoid on a rotary compressor tied back into the suction side with a super fast on/off cycle to see if you could cut back on displacement with out messing something up. lol
