  • Publication number: 20230235927
    Abstract: A system and method for the applying solar heating to an absorption cooling system. Described is either single or double absorption cooling systems in which in a first embodiment the normal generator function of a traditional absorption cooling system is removed from the absorption cooling system and is placed within a solar parabolic trough that acts as a hybrid solar absorber/generator for the absorption cooling system. In a second embodiment the normal condenser function of a traditional absorption cooling system is also removed from the absorption cooling system and placed within the solar parabolic trough, resulting in a hybrid absorber/generator/condenser of the absorption cooling system.

  • Publication number: 20230110838
    Abstract: A system and method for the removal of volatile components from a liquid or a slurry containing solids and liquids and using a screw conveyor or auger systems that transfers solid/liquid slurries through an elongated tube heated by solar energy from a parabolic solar trough. The system flashes off the volatile component then counter-currently flows that vapor back into the hollow pipe inside of the augur creating a Multi-effect or Multi Flash device which greatly improves the overall efficiency of removal of the volatile material.

  • Patent number: 11285400
    Abstract: A solar distillation system includes solar panels, and receivers adjacent the solar panels to receive process water to be processed to purified process water. The process water flows from a first receiver to a last receiver and is heated by reflected sunlight. Vapor tubes are coupled to the receivers, with each respective vapor tube coupled between adjacent receivers. Water vapor is generated as the process water is heated within each receiver. The water vapor flows via the respective vapor tubes between the adjacent receivers towards the last receiver. A return vapor tube is coupled to the last receiver. A distillation tube is coupled to the return vapor tube to receive the water vapor. The distillation tube extends through the receivers from the last receiver to the first receiver. As the water vapor travels through the distillation tube it changes to a liquid, with the liquid being the purified process water.

  • Publication number: 20140246011
    Abstract: A solar heat exchange panel that includes a lower plate and an upper plate that together define an interior volume containing a flowing heat transfer fluid. The upper plate includes a plurality of upward extensions and downward extensions that cover the top surface of the solar heat transfer panel and are configured to capture solar radiant energy. The lower plate plate includes a plurality of upwardly extending hollow lower plate extensions. The lower plate extensions are aligned with the bottom portions of each upward extension of the upper plate and almost touching. Each of the downward extensions form the upper plate extend down and are joined to the base of the lower plate. In operation, a heat transfer fluid introduced into an inlet on one end of the solar heat transfer panel passes through the defined interior volume and is intimately contacted with the solar heated surfaces extending down into the solar heat transfer panel from the upper plate.

  • Patent number: 8691038
    Abstract: The present invention relates to a method of forming a molded article (e.g., 141) from first and second heated and thermoformable thermoplastic sheets (75, 78), which are each respectively formed in situ from first and second thermoplastic compositions (e.g., by means of extrusion). The heated first and second thermoformable sheets are each drawn by reduced pressure into contour matching contact with the interior mold surfaces (14, 32) of separate first and second mold portions (11, 29), so as to form separate first and second profiled thermoplastic sheets (129, 144) within the separate mold portions. The first and second mold portions (11, 29) are positioned towards each other (e.g., together) so as to bring into contact and fuse together contact portions (159, 163) of the first and second profiled thermoplastic sheets (129, 144). Fusion between the contacted contact portions (159, 163) is achieved by means of (e.g.
