TREV - Temperature Responsive Expansion Valve

[desA]

I recently came across a writeup on the Sporlan Y-1037 Temperature Responsive Expansion Valve. It looks to be an interesting concept.

I would appreciate feedback on members' experiences - good & bad - with the TREV.

A few questions:
1. How well does the injected 2-phase mixture mix with the evaporator discharge?
2. Is a special injector required?
3. Is a suction accumulator required?
4. Do electronic versions of the TREV exist?

Thanks folks for your comments.

Thinking Prof Sporlan could tell us all about this, but haven't seen any of his posts for quite some time.

Thanks, Gary.

I think Prof Sporlan is still around. I met some folks from Sporlan Singapore a while back & they were in communication with him. Perhaps he's just not active on RE?

Pity, as some of his earlier posts were stunning.
