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. The third mode of operation provides cooling in the absence of solar radiation by the use of the stored refrigerant and subsequent combination of the refrigerant with absorbent which fluid is then stored in a separate reservoir.
The system also is provided with a solar tracking arrangement by which one or more solar collectors will be automatically oriented directly toward the sun for assuring maximum utilization of the sun's energy.
