Abstract:
1. A method of solar-powered adsorption-desorption refrigeration that provides cooling over a first time period and a second time period, comprising the step of: providing a first bed of adsorption media of a first nanostructural material made of an first aerogel, providing a refrigerant to the first bed of absorption media; providing a first shade adapted to selectively block sun energy from said first bed of adsorption media; providing a second bed of adsorption media of a second nanostructural material; providing a second shade adapted to selectively block sun energy from said second bed of adsorption media; providing a condenser and an expansion valve fluidly connected to the refrigerant in the first bed of absorption media; enabling said first bed of adsorption media to receive sun energy during the first time period; circulating said refrigerant from said first bed of adsorption media to said condenser and expansion valve to provide cooling during the first time period, enabling said second shade to block sun energy from said second bed of adsorption media during the first time period; circulating said refrigerant from said condenser and expansion valve to said second bed of adsorption media during the first time period; enabling said second bed of adsorption media to receive sun energy during the second time period; circulating said refrigerant from said second bed of adsorption media to said condenser and expansion valve to provide cooling during the second time period, enabling said first shade to block sun energy from said first bed of adsorption media during the second time period; and circulating said refrigerant from said condenser and expansion valve to said first bed of adsorption media during the second time period.
