  • Publication number: 20120096884
    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 (CO2) 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.
