Morphing Air Conditioner into Autocascade System

[PhilippF]

If I get it right: You dont charge every refrigerant in a row but start with 2 mixtures (R123/22 and R170/14) and change the ratio of these two mixtures in the tuning process?

EDIT: I wanted to charge the following way (please correct me if I tell nonsense):

Vacuuming and then breaking with R123 up to 1 barg (2 bara). Adding R22 up to 3 barg (4 bara) and then adding R23 up to 5 barg (6 bara). I imagine this will be a nice starting mix. Then turning the unit on and watching the first HX (where R22 mainly should evaporate) and perhaps add R22 until I have no significant temperature differential along the HX (I picture then being enough R22 to be there to cool the whole HX). Then repeating the same thing with the Evap (for R23). Do you think this will work?

Regards and thanks,
