AC,
I just read the paper you presented. Is this awesome or what? Exploiting supersonic evaporator flow for efficiency gain! The author admitted he shoulda used a larger accumulator because he slugged his compressor! Priceless...

I hope the next version will support sustained operation. It would be a tremendous innovation.

I don't know if my unit was producing supersonic flow, I highly doubt it, but it was doing the same thing as the author described in his paper. Right at the point where efficiency was greatest, the evap would burp foam. I wasn't slugging my cxr, I was foaming it. I believe it was at around 10 deg F of superheat at the bulb, 15 deg f at the cxr inlet. from this effect, I learned how hard I could push my evaporator.
