Morphing Air Conditioner into Autocascade System

[godmod]

No problem using reciprocals. just so long as motor size vs. displacement is reasonable (medium to high back pressure).

Thanks for the Info.
edit: ok, i already thought this. and of course R404a comps would be better, because of stronger motor (high HP)

This way some liquid will be passed on to the next stage along with what ever gas is present, there by insuring that a disconnection between stages doesn't occur (as what happened to me on my R-600/R-170 charge test).

Some experimentation will be needed to find the optimum height for the exit tube.

The right "length-setting" might be really hard to find. Aren't the liquid levels loaded different than in idle? The problem i see here is that "the gas out pipe sucks" either liquid or gas. There will be an alternating oscillating gas-liquid compositon. I visualize that that way: a constand volume flow out of the strainer through the gas-discharge. the composition will be, depending on the refrigerant level in one moment liquid, until level drops, then gas until liquid is high enough. maybe sometime it will equilibrate, but I think varying load could cause a oscillating system (keyword: feedback). Just thoughts, might also be delusions
