Well since project is near complete I will post up here
1st stage:
3/4+ hp condensing unit (has low pressure cut off... will see if it works as i hope it does..)
SLHX (shell tube thing...)
Danfoss TUAE TXV... i just don't like flare if I can get away with it. External pressure equalized.
Swep plate hx.
2nd stage:
1/2+ hp compressor
Condenser for my usual v2000 unit for desuperheater.
SLHX 3ft of 5/16 in 1/2
Captubing to Evap (chilly1 evap)
Yellow jacket 3/8 stainless steel flex line (flare end on each)
Highside cut off switch.
MISC:
Gauges for each stages (low and highside)
Electricals: (not in yet)
relay to cut off low side if high side isn't on.
wall switches for turning unit on and off.
2 fans for condenser and compressor cooling.
Almost done except electrical lines for easy operation and some finishing touches...
Load 150w @ -95c, Load 200w @ -93c. Also discharge while fully loaded is only around 170-180 psi which makes me feel better about safety. When idling, very low discharge hehe...
