Solar Powered Air Conditioner, which is powered directly by solar energy with no need of conversion to electricity, hence no emissions of Carbon Dioxide

Abstract

We present a Solar Powered Air Conditioner (SPAC) which is powered directly by solar energy obtained by dynamic sun-tracking concentrators with no conversion to electricity. SPAC does not contribute to carbon dioxide (CO 2 ) emissions that come from the generation of electricity, it does not lose energy due to conversion and it has no need of solar panels. SPAC uses refractive or reflective sun-tracking concentrators to concentrate sunlight into the heat required to power a cooling system.

1 . A Solar Powered Air Conditioner system, SPAC, comprising of sun-tracking concentrators (refractive or reflective), a gas absorption refrigeration mechanism, solar powered fan, and an alternate source of power, concentrates sunlight to generate the heat necessary to power a closed gas absorption refrigeration cycle with no need of conversion to electricity. 
     
     
         2 . A Solar Powered Air Conditioner system according to  claim 1 , can be used for refrigerators, freezers, and multiple other applications that require cooling. 
     
     
         3 . A Solar Powered Air Conditioner system according to  claim 1 , uses one or more sun-tracking refracting lenses to continuously and quickly concentrate the heat of the sun's rays to heat a component of the SPAC. 
     
     
         4 . A Solar Powered Air Conditioner system according to  claim 1 , uses one or more sun-tracking reflective concentrators or mirrors to continuously and quickly concentrate the heat of the sun's rays to heat a component of the SPAC 
     
     
         5 . A Solar Powered Air Conditioner system according to  claim 1 , relies on the expansion/cooling cycle of a refrigerant or a combination of refrigerants. 
     
     
         6 . A Solar Powered Air Conditioner system according to  claim 1 , converts a refrigerant to a gaseous state by heating it with continuous concentrated solar energy that is produced by sun-tracking refractive or reflective continuous concentrators. The gasified refrigerant is condensed and passed to an evaporator. Rapid evaporation requires the absorption of surrounding heat. 
     
     
         7 . A Solar Powered Air Conditioner system according to  claim 1 , can also power photo-voltaic panels or other forms of energy. 
     
     
         8 . A Solar Powered Air Conditioner system according to  claim 1 , is equipped to operate with stored solar energy by use of a battery, or other energy sources (electricity or gas) when conditions require it.

         12 . The sun-concentrators of the Solar Powered Air Conditioner system can be used to produce electricity to feed back into the local grid during times when cooling is not needed. 
     
     
         13 . (canceled) 
     
     
         14 . A Solar Powered Air Conditioner system according to  claim 1 , has multiple applications: Can be used in new building construction, could be added during remodeling or retrofit work as well. It has applications in residential, commercial and industrial areas, or could be provided as an add-on kit or conversion kit. It can also be used as a free-standing air conditioner. It has applications on mobile units: Can be used in military or medical units, tents, recreational vehicles, equipment, and the like. It can also be used for cars, truck cabs, refrigerator trailers, tanks and missiles. It uses excess heat (usually lost energy) to cool down the car's compressor, batteries, controls, units and equipment.
