An adsorber includes: a closed container in which an adsorption medium is included; an adsorption part that is provided in the closed container and includes an adsorbent, which adsorbs and desorbs the adsorption medium; and an evaporation/condensation part that is provided in the closed container and that exchanges heat between the adsorption medium and a heat exchanging medium, which is supplied from outside of the closed container, to evaporate and condense the adsorption medium. The evaporation/condensation part includes a heat transfer part that transfers heat of the heat exchanging medium to the adsorption medium. The heat transfer part is capable of holding the adsorption medium, an amount of which is capable of being adsorbed by the adsorbent of the adsorption part.

The present invention pertains to systems, methods, and compositions for liquid phase change, including for active cloud point, e.g., critical solution temperature, adjustment and heating or cooling, e.g., refrigeration, cycles. In some embodiments heat is absorbed, released or both due to phase changes in a liquid system. Advantageously, the phase changes may be controlled by controlling the ingredients or amounts of certain components of the liquid system. Advantages may include lower capital expenditures, lower operating expenses, or both for a diverse and wide range of heating and cooling applications. Such applications include, for example, cooling of data centers, cooled transportation of goods, refrigeration, heat pumps, extractions, ocean thermal energy conversion, and de-icing of roads to name just a few.

Adsorption heat exchanger devices (11, 30) are provided for solid sorption refrigeration systems (1). Such a device includes a heat exchanger (12) having a plurality of projections (17) arranged for extending into an adsorbate of the system (1) in use. An adsorption structure (13, 31) is formed on the heat exchanger (12) for adsorption of said adsorbate. The adsorption structure (13, 31) comprises a plurality of elongate adsorption elements (20) extending outwardly from each of said projections (17) of the heat exchanger (12).

The invention relates to the design of an air cooled absorption machine. Said machine has a hollow design via which air can circulate inside same by forced convention having a parallelepiped form. The air enters by suction via the sides and leaves via the upper face of the machine, where the ventilator is located. The machine comprises falling-film heat exchangers with improved designs for heat and mass transfer.

The present application pertains in some embodiments to a thermal storage system. The system may include, for example, a warm thermal storage region; a cold thermal storage region; and a physical divider. The warm thermal storage region may include at least two liquid phases. The cold thermal storage region may include at least one liquid phase. The physical divider substantially separates the warm thermal storage region from the cold thermal storage region.

A sorption module for a sorption temperature-control device may include a housing enclosing a working chamber. A sorption zone and a phase change zone may be arranged in the working chamber where a working medium is displaceable reversibly between the sorption zone and the phase change zone. A sorption structure may be arranged in the sorption zone, and a phase change structure may be arranged in the phase change zone. An outer wall of the housing may include a double-walled section that may provide a cavity between an outer wall part and an inner wall part of the double-walled section, and the phase change zone may be arranged on an inner side of the inner wall part.
