A liquid-gas heat exchanger for use in a heat exchange system using solar energy has an insulated chamber adapted to allow hot air to pass therethrough. A coil member extends through the insulated chamber and is adapted to allow a heat transfer liquid to pass into and then out of the insulated chamber. The spacing between the windings of the coil are predefined and the coil is in a predetermined position inside the insulated chamber, so as to force the air to pass in between the coil windings and increase the air contact with the coil and provide a large heat exchange. Several baffle members are placed each side of the coil member and an interior area of the insulated chamber and force air to circulate multiple times through the coil member, thereby allowing for an efficient exchange from the hot air to the heat transfer liquid. The insulated containe contains the heat exchanger which is comprised of a plurality of chambers, wherein each the plurality of chambers has a repeating pattern of shapes wherein each of the chamber of th plurality of charribers consists of one deflector which deflector being opposite to another deflector, which other deflector is a mirror image of its opposite deflector but shifted approximately half a the wall length. Each of the deflectors is defined by a specific sequence of components starting with a rounded wall from which extends a shear barrier and the wall is terminated by a diverter.

Various implementations include solar thermal energy collection system comprising a solar energy concentrator, a heat transfer fluid, an absorber pipe. The absorber pipe includes a pipe wall and has a central longitudinal axis. The pipe wall has an inner surface and an outer surface. The inner surface has a first contour defining alternating peaks and troughs along a length of the absorber pipe. The outer surface has a second contour defining alternating peaks and troughs along the length of the absorber pipe. The inner surface defines the entire flow path for the heat transfer fluid through the absorber pipe. The first contour, as viewed through an axial cross section of the absorber pipe, forms sinusoidal waves on each side of and spaced apart from the central longitudinal axis. The sinusoidal waves on each side of the central longitudinal axis are symmetrical with respect to the central longitudinal axis.

A building integrated photovoltaic and thermal energy system is disclosed. The system includes photovoltaic panels integrated into glass structures that may replace existing designs of skylights, atrium windows, building facades, and other applicable structures while converting sunlight to electricity. The system also includes a thermal energy system configured with the photovoltaic system to convert sunlight to thermal energy. The integration of the system into building structures provides an aesthetically pleasing structure while generating required power.

A solar collection system includes an absorption refrigeration system to generate water from atmospheric moisture, and to do so without the use of an electrically operated compressor. At least a portion of the solar energy captured by the solar collection system is used to operate the absorption refrigeration cycle. The absorption refrigeration cycle provides cooling that causes water in the atmosphere to condense into a liquid that can be collected and used for various applications. As one example, the collected liquid can be used for the cleaning of the solar collection system of contaminants like dust or bird drippings. In other applications, the water can be used outside the solar collection system including, but not limited to, irrigation, drinking, and other industrial purposes.
