Hi Members, We have a simple digital technology to reduce refrigerant quantity by 80%. This technology can be used in every dry expansion plant.
The thermostatic valve and the liquid receiver are not required.
A plain solenoid valve, without any orifice, pulses on and off to regulate the evaporator feeding.
Details and a full example are posted on our web site micheletti.org .

Can I respectfully ask how this compared to an electronic expansion valve, which also seems to pulse the flow?

The ReFreeX™ advantages
The environment
• 80% reduction of refrigerant charge and then greenhouse effect
• less lubricating oil thanks to refrigerant reduction
• reduced metal thickness in piping thanks to no PED (97/23/EC) applicability

How can these claims be justified, in practice? I'd like to know if other folks have used this system & what their experiences were.

Where does the 80% refrigeration claim arise from? A saving in liquid volume? This seems to be the main claim I can see.

I'm trying to understand the substance & essence of the claim - not quite sure the thermodynamics adds up in my head at the moment. I'd like more information.

hello
can you explain how can we reduce the refrigrant charge to 80%
?

weird. i dont know if i belive that. how the hell can you still flood the evap with refrigerant if theres 80% less in a system?

I work for a refrigeration equipment manufacturer, woul you allow full R&D testing of your product?
