Ultrasonic Air Conditioner

Water-cooled airconditioning systems (WACS) use evaporative cooling to chill air which is circulated around buildings. The basic mechanism is a water pump connected to a spray nozzle array that sprays a mist of water over a heat exchanger. If you've seen these units working, you can see unevaporated water cascading down the inside to be recycled. This has to be inefficient to some extent, though WACS are already much more efficient than conventional compressed gas A/C systems.

Ultrasonic humidifiers produce "cold steam" by sonically atomising water with a relatively low-power (a few watts)ultrasonic transducer. They are believed to be more efficient than a heated humidifier or a spray unit (and safer and more compact too).

I want to combine the two and create an ultra-high efficiency, compact, silent (in the audible spectrum) air conditioner. Enhancements would include a fresh-air blower to increase air flow through the evaporation chamber.

I am fairly sure this idea is novel. I have subsequently found a link (provided) to an ultrasonic atomizer cooling unit for a furnace. The link describes also household humidification, but does not make the connection to its use in air conditioning. I have found no links to the system I describe in the application I propose.
