ABSTRACT:
Solar powered refrigeration apparatus is disclosed in which an absorption refrigeration system is operated directly by solar energy. One end of a heat pipe is thermally connected to the boiler of the absorption refrigeration system, and a solar collector is thermally coupled to the other remote end of the heat pipe. The heat pipe is a sealed, evacuated metal tube partially filled with water. The solar collector is a double walled glass vacuum tube with a central axial opening for accommodating the remote end of the heat pipe. Heat energy collected by the solar collector boils the water in the heat pipe to subsequently condense in the area of the boiler thus transferring heat energy along the heat pipe to the boiler. The heat pipe is installed sloping downwardly away from the boiler to permit the return of condensate down the pipe to the solar collector area thus permitting continuous operation.
