Long story short!
First rigg, just modified an existing rigg nothing to special, to see if there was potential, had possible results.
(also some flawed testing) because part of the design is to consider what happens if there is a failure with the widget (cause and effect)
Built purpose rigg, with 100% isolation and by-pass of each and every component. So it can be run as 100% conventional or 100% with widget and all steps im-between
can control load (flow and temp), pressure, Superheat, sub cooling, and condensing flow rates.
Basically we are measuring for results cooling capacity, power draw and heat rejected, whilst measuring the parts of the refrigeration system to ensure that we keep with component specifications.
The TVR could be wrong (venturi type device) more than one size and the wrong type, the vessel could be wrong, asumed peak performance may be wrong.
