Air cooler

Abstract

This invention allows a common centrifugal blower (fan) to be used to produce cold air for comfort cooling purposes. It uses no chemicals, has no compressor, and does not require a drain since it produces no water while operating. It has been tested in my home, and was used to cool a large tent while family camping. It cooled the tent in 95 degree weather with excellent results. With the addition of the invention to a furnace blower, it can pre-cool air entering an existing conventional central air conditioning system and save energy, or the furnace blower itself could be used as the central air system. in the winter, for furnace heating use, one needs just block the resonator inlets and the blower functions as a normal blower. A smaller blower, like the prototype used for camping, is completely portable and does not need to occupy any windows, as in a window a/c unit. It is extremely environmentally friendly. I have searched the internet world-wide and have found nothing like this device anywhere.

What I claim as my invention is:  
     
         1 . The system and method described in the detailed description of invention- using resonators and a blocking damper to cause centrifugal blowers (fans) to separate hot and cold ambient air fractions for comfort cooling purposes:
