Another alternative to compression type air conditioners is Coolerado. There are many advantages to this type of cooling system. They have only two moving parts: a fan and a solenoid valve. There are no chemicals such as freon. They use a fraction of the electricity needed to power conventional air conditioners. They draw in fresh filtered air from the atmosphere, rather than recirculating air winthin the building. And the cost, including installation is less than for conventional air conditioners.
These devices work by separating hot air from cold air using water. Unlike conventional evaporative coolers, they also separate moist air from dry air. The moist hot air is ducted back to the outside atmosphere. The cool dry air is delivered to the room to be cooled.
The demonstration Coolerado unit had 156 degree heat appied to the input of the unit.
Which was converted to 55 degrees on the output.
The above graphic shows the temperature profile of the test unit. The hottest air, indicated by red exits out the top left of the unit. The remaining cool air, indicated by blue, is produced at the output on the bottom right. You can view the full three videos at the Coolerado Tech-Info Page.
