Abstract: The invention relates to a method for exchanging heat contained at a fluid. A gas which is heated indirectly and emits infrared radiation is used as the fluid, said fluid being guided to the heat exchanger via an inlet and through art absorber chamber in the heat exchanger, and at least one surface, which absorbs the infrared radiation of the gas in order to use the heat of the gas, is provided in the absorber chamber. The mass flow and the temperature of she gas are additionally adjusted and the at least one surface which is absorbent for the heat exchange is designed such that the ratio Ψ of the heat flowing through the surface as a result of absorption to the total heat flowing through the surface is ≥0.6 during operation. Thus, a simpler and less expensive heat exchanger can be implemented.

Abstract: 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.

Abstract: Two sensible thermal energy storage (STES) systems in multiple chambers containing molten eutectic salts have been devised for use at temperatures above 565° C. For the first type, the thermal energy of low specific heat of an immiscible gaseous heat transfer fluid (HTF) at temperatures above 900° C. is readily converted to dispatchable heat of high specific heat in the molten eutectic salt liquid layers operating at high temperatures, which can again produce a gaseous HTF at a constant temperature of 700° C. or higher for the lower electricity generation capacities. For the second type, the molten eutectic salt liquids are used as a thermal energy storage (TES) medium and also a HTF at temperatures above 700° C. for the higher electricity generation capacities. These STES systems provide an effective cushion against the disturbances of heat supply from the sun.

Abstract: The disclosed invention relates to solar-thermal receiver tubes for heating high-temperature fluids such as molten salts and oils, such as those used in conjunction with trough reflectors or concentric concentrators. The disclosed invention utilizes fused silica receiver tube assemblies that provide optical absorption by way of optically-absorbing media that is imbedded within the thermal transfer fluid, preferably comprising inorganic “dyes” that comprise pulverized thin film coatings or dissolved materials that are specifically designed for maximizing optical absorption. Alternatively, the chemistry of the transfer fluid can be modified to increase optical absorption, or the optically absorbing media may comprise fine powders with density preferably similar to the thermal transfer fluid, such as fine graphite powder; or, in another preferred embodiment, absorbing means within the heat transfer fluid comprise a solid absorbing element disposed along the central axis of the receiver tube's interior.
