A bit puzzled by the claims. The heat has to be removed somehow, and heat transfer requires an energy input. How does this system of refrigeration work so much more efficiently than a regular air conditioning system? At the end of the day, a bunch of warm air is cooled and the waste heat is rejected. Why would a bunch of little-bitty air conditioners be more efficient than one big one?
I understand that they're using a single-point compressor and distributed heat exchangers, but I still don't see where the savings are. Dumping the waste heat into an external sink (groundwater, a convenient river nearby, evaporative cooling tower, etc.) would improve efficiency, but that doesn't appear to be what they're doing.
