摘要： A building-integrated solar energy system that concurrently provides space heating, space cooling, hot water, and electricity to commercial and residential buildings. The solar energy system comprises an evacuated closed-loop conduit network circulating a working fluid through a solar thermal collector and at least one heat usage device, wherein the effective entirety of the surfaces of the closed-loop conduit network are in contact with the working fluid such that phase change occurs whenever heat energy is added by the solar thermal collector or removed by a heat usage device. The solar energy system further comprises an impermeable outer housing enveloping the closed-loop conduit network and forming an evacuated space located between and defined by the outer surface of the closed-loop conduit network and the inner surface of the impermeable housing such that the working fluid is adiabatically isolated. As a result, the full surface contact and low-pressure isolation of the working fluid dramatically reduces temperature differentials and energy losses, allowing for highly efficient and cost-effective heat collection and distribution.

摘要： A solar water heating system can be implemented utilizing an innovative flat-shaped heat pipe as a primary heat transfer device. The system can include two small insulated rectangular ducts at the top and a large insulated rectangular duct at the bottom of the flat-shaped heat pipe. An absorber, positioned to receive, collect, and transfer solar heat, can be integrated into the system, complemented by a glass cover to minimize heat loss. The flat-shaped heat pipe, which can be constructed from a copper plate with porous wicks on its inner surfaces, can be filled with a working fluid. Solar irradiation incident through the glass cover on the absorber triggers the evaporation of the working fluid, absorbing latent heat. Subsequently, the vapor moves and transfers evenly to both sides of the flat-shaped heat pipe, facilitating the transfer of heat to water flowing through the rectangular ducts situated outside the flat-shaped heat pipe. This configuration optimizes energy efficiency, offering a reliable and cost-effective solution for solar water heating applications.

摘要： Solar thermal devices are formed from a block of wood, where the natural cell lumens of the wood form an interconnected network that transports fluid or material therein. The block of wood can be modified to increase absorption of solar radiation. Combining the solar absorption effects with the natural transport network can be used for various applications. In some embodiments, heating of the modified block of wood by insolation can be used to evaporate a fluid, for example, evaporating water for extraction, distillation, or desalination. In other embodiments, heating of the modified block of wood by insolation can be used to change transport properties of a material to allow it to be transported in the interconnected network, for example, heating crude oil to adsorb the oil within the block of wood.

摘要： A heat-activated fluid pump heats and cools a building. For cooling, an evaporator, coupled to a solar heater or comprising multi-pane windows with solar radiation-absorbent areas thermally coupled to a fluid cavity, converts a working fluid into a vapor. A pressure control valve allows vaporized working fluid into a liquid-piston chamber whenever a target pressure in the evaporator is exceeded. The working fluid expands, displacing liquid from the liquid-piston chamber in a pump stage where it enters a condenser situated in a vertical hole or covered horizontal trench in the ground. Ground-temperature pumped fluid returning to the liquid-piston chamber in a suction stage passes along the way through coils in rooms of the building. Check valves allow replenishment of the evaporator with return working fluid and direct flow of pumped fluid into and out of the liquid-piston chamber. For heating, the evaporator is in the ground.

The system comprises a windshield, a flat heat absorber, and a circulation pipeline, wherein the flat heat absorber is a main element for photothermal conversion and heat energy transfer, the windshield prevents heat loss of the heat absorber, and the circulation pipeline ensures the circulation of a working fluid. In a working process, a heat transfer fluid in the flat heat absorber absorbs heat and evaporates from an evaporation surface, releases heat and condenses on a condensation surface, the condensed heat transfer fluid flows back to the evaporation surface to enter circulation work of a next round, and heat is transferred to the working fluid by means of a gas-liquid phase change process. According to the flat heat absorber, by means of structural innovation and the arrangement of grids, the height of the heat absorber is reduced by more than half compared with a conventional heat pipe heat absorber, the windward area is reduced, the center of gravity is reduced, and the stability of the heat absorber is improved. Moreover, a heat pipe principle is used for indirect heat transfer, such that the flat heat absorber can tolerate high heat flux density and thermal shock, and the service life of the flat heat absorber is prolonged.
