<VV> AC - Non-Corvair

[JVHRoberts at aol.com]

It wasn't without its problems, and I believe this is what killed it.
1. It required exceptionally well filtered air to prevent wear and  premature 
failure of the compressor/expander components. Failure to change these  
filters, or running without them meant very short life. Not a problem with  
condensers and evaporators. 
2. There was a VERY big problem with how to collect the condensation/ice  
crystals that came out with the discharge, and that same condensation required  
corrosion proof construction of the compressor/expander unit.
3. It never lived up to its performance claims. The COP of conventional  
mechanical vapor compression refrigeration was higher, in real life, than the  
ROVAC system.

Does  anyone know what happened to the ROVAC air conditionong system that was 
 promoted by the Rovac Corporation of Rockledge, Florida?  It was highly  
touted for a while and then the idea disappeared.  Why?
I'm curious as  I found some old notes of mine for a version of it that would 
eliminate the  noise problem that I heard that it had.
Any info out  there?
