Single-stage auto-cascade build

[tiborrr]

@Gomeler: Thank you, buddy. I try to keep my expectations low, but still I'm excited as the project is about to enter the 'charging phase'

@[ 486 ]: Yeah, I purged the lines with nitrogen shielding gas. Used about 1/5 of the 10kg tank just for purging and pressure testing. I'll try to avoid R-290 in the charge as it will 'contaminate' the CO2 charge, making the final CPU evaporator temperatures warmer. I think Mytekcontrol's topic explains this the best.

See, almost emptied my N2 tank :


@captaincascade: I'll keep that in mind, sir!

Here is the final auto-cascade HX assembly with SLHX (refered as 'auxillary' HX by Mytekcontrols), main cascade HX and a liquid/gas phase separator. Had a few leaks at the T-joints, repaired them quickly and now the assembly appears to be leak-proof (still under nitrogen charge):



The long horizontal lines are compressor discharge (condenser) and compressor suction. The port, which is at the moment brazed shut, coming from phase separator's gaseous line is for the direct bypass (of gaseous refrigerant directly to expansion tank).

Best Regards,
