Don't you like it painted?
TXV is a Alco TI-SW with a TIO-01
Today, I've prepared 1st stage succion line, and adjusted TXV outlet. Then I've brazed them to the HX along with 2nd stage liquid line side at the same time.
Guess I'll be able to finish the work tomorrow and start testing.

Brazing work is finished. It remains leak testing, wiring and insulating.

Very nice :-)
1/2" Insulation? That all you've found you need?
If you have a cooling question or concern feel free to contact me.
@Luke: Thx mate
@n00b: I get several different insulation materials.
Apparently there's no leak so I've started insulating.Did few tests with R290, and both stages look to work.

very nice before, this has to be your cleanest unit yet mate, well done
When you build you don’t much around do you
that is AMAZING!! Really quite clean. Even the insulation is done expertly. Hats off to you

Thank you so much guys
Insulation isn't finished yet... BTW I couldn't resist to test 1st stage a bit.
T1 = evap
T2 = suction
Difference between 2 temps is a bit high IMO; BTW TXV is to used with R404a instead of R290 and insulation is messy.

I've performed some tests with R290 into 1st stage and R1150 into the second one.
2nd stage went down to -112C unloaded with CPEV almost shut... Not really good ATM.
BTW insulation is still in its early stages and thus it might explains why the temp is so "hot".
Anyway, dunno if the actual captube (2mm; 1.5m) is good or not to properly use the CPEV.

Really nice unit my friend
What was first stage temps when you run secoond stage compressor?
It is but you will have some fun with CPEV, before you will set it.Anyway, dunno if the actual captube (2mm; 1.5m) is good or not to properly use the CPEV.

what are the low side pressures on the cpev?

First stage temps are very bad while 2nd stage has been running:
About -50C HX input to -40C output... very unstable.
Coldest temps so far were -67C HX inlet / -60C outlet unloaded. BTW the matter is, the TEV must be used with R404a and unfortunately, I've ran out of it. I only have some R290 ATM. I hardly need some R404a.
Lowest one so far was 0.6bar.

hé ben !!
ça me trou le cul ton savoir faire xav !!!

CPEV is nothing more than mechanical device that reacts to pressure. I don't see why it can't be used with other refrigerants. I am using one now on mini-c and have no issues with 4 different gases I tried on it with vastly different properties. I presume you are using it on first stage?

CPEV deals with pressures an viscosity. Both of them depend on the gas and the way the CPEV work will change
I'm shure he wants to write TXV....
Merci Seb

Wanna see how fast 2nd stage goes down?

Heh, nice. Guess the load tuning for unit is quite good already

Off course
Nice video!
Managed to fix the first stage already?
Not yetI've ordered 2kg of R404a to Kaeltetechnik-Shop (cold_ice's shop). Hopefully, this refrigerant will fix the matter.

Xavier

I'm performing the very first tests over a clocked CPU. Not too much ATM because I've picked up the wrong E6850Nevermind.
Evaporating temp is -106.5C (0.86bar) during Spi32M at 500x9 @1.72v.
Not bad, but not good enough. CPEV is at its lowest available pressure. I'll wait for the R404a first, but it might be interesting to add some 0.9mm captude.
Best Regards,
Xavier
