At a trade show Saturday in Atlanta I heard about a solar heat pump that uses refrigerant circulated through solar collectors to heat and cool a residence.  I was told that it was not Lennox's solar-assisted SunSource heat pump.  This new one is supposed to be a modified Westinghouse unit.  So far, I have not found a web site for this new solar heat pump.  Anyone aware of this new type of heat pump and have a web site for it?

Rotartica (Spain) has been out there for a couple of years now with with solar absorption chiller technology. Haven't seen anything along those lines from Westinghouse.
