Hi Jeff , some good ideas there .
I think i will K.I.S.S . May be if i had included a reciever in the design it may of been worth thinking about . With a system that has 2 plates the refrigerant charge is as small as you can get it , there would be a large variation in refrigerant needed for air coil compared to plate. Also oil could get trapped in any shut down part of the suction system . The prices of refrigerant in NZ have gone from $250 for 13kg to $1200 in the last 5 years so the smaller the charge the better.
All correct with your research on the Daikin Jeff , did you find out how much oil was in the compressor ? This took me ages to find , i changed from mineral to poe so i could run the r407f.
