Abstract

A solar-powered adsorption-desorption refrigeration and air conditioning system uses nanostructural materials made of high specific surface area adsorption aerogel as the adsorptive media. Refrigerant molecules are adsorbed on the high surface area of the nanostructural material. A circulation system circulates refrigerant from the nanostructural material to a cooling unit.

Claims (12)

1. A solar-powered adsorption-desorption refrigeration apparatus that provides cooling from energy from the sun, comprising:

a first bed of adsorption media positioned to receive energy from the sun;

said first bed of adsorption media comprising a first nanostructural material made of a first aerogel;

a refrigerant in said first bed of adsorption media;

a second bed of adsorption media positioned to receive energy from the sun;

said second bed of adsorption media comprising a second nanostructural material made of a second aerogel;

said refrigerant in said second bed of adsorption media;

a cooling unit;

a circulation system for circulating said refrigerant from said first bed of adsorption media to said cooling unit to provide cooling from energy from the sun and from said cooling unit to said second bed of adsorption media, and

a retractable shade positioned between said second bed of adsorption media and the sun.

2. The solar-powered adsorption-desorption refrigeration apparatus that provides cooling from energy from the sun of claim 1 wherein second aerogel of said second bed of adsorption media has pores and wherein said refrigerant is absorbed in said pores.

3. The solar-powered adsorption-desorption refrigeration apparatus that provides cooling from energy from the sun of claim 1 wherein first aerogel of said first bed of adsorption media has pores and wherein said refrigerant is absorbed in said pores.
