  • Patent number: 4281515
    Abstract: The system contains an unique solar collector for transferring heat energy from the sun to a solution comprising a two-phase refrigerant and a fluid absorbent. Solar radiation causes a vaporization of the refrigerant which exits from the solar panel through a separate path from the remainder of the fluid. The vaporized refrigerant is returned to a liquid state and passed through an evaporator in a lower pressure environment for producing a cooling effect. The refrigerant is recombined with the absorbent and returned to the solar collector in a high pressure environment.Three modes of operation are included in the system. Continuous cooling being the first mode. The second mode consists of storing the liquid refrigerant after separation from the refrigerant absorbent fluid. The refrigerant and absorbent are stored for future use.
