摘要： Disclosed herein is a power-to-water (P2W) battery and its use for converting atmospheric water vapor into water by surplus renewable energy. The P2W battery includes, a thermal energy storage (TES) unit made of high-storage-density media for storing heat; a hygroscopic solution container consists of an inner container made of a conduction material for receiving the TES unit therein, a water vapor permeable membrane disposed outside and around the inner container, a hygroscopic solution disposed between a space formed between the inner container and the water vapor permeable membrane; and a condenser disposed downstream and coupled to the hygroscopic solution container; wherein the hygroscopic solution is capable of absorbing the atmospheric water vapor, which is released by heat stored within the TES unit when the TES unit is received in the inner container; and the atmospheric water vapor released from the hygroscopic solution is condensed into water by the condenser.

摘要： A membrane-based desorption cooling method for passive thermal management is presented. The module includes: (i) a covering layer for thermally conducting and transferring heat from a device to a solution; (ii) a solution layer for confining H2O/absorbent mixtures in a multi-compartment frame; (iii) a membrane layer configured to act as an interface between the solution and air; and (iv) a supporting layer configured to increase the mechanical strength and including apertures to permit mass transfer from the membrane through the supporting layer. The present membrane-based desorption cooling module is able to be used for thermal management of solar photovoltaic (PV) panels, electronics, batteries, or any other devices that require heat removal.

摘要： The present invention presents a thermochemical energy storage system. The system includes a membrane-based thermochemical reactor. The reactor includes a solution channel having an absorbent-containing solution flowing therethrough and a refrigerant channel having a refrigerant flowing therethrough along with first and second fluid channels. A porous membrane is positioned between the refrigerant channel and the solution channel; the porous membrane permits flow of vapor molecules therethrough while restricting flow of absorbent molecules. The system further includes a solution storage repository in fluid communication with the solution channel and a refrigerant repository in fluid communication with the refrigerant channel. The system can be used in high-density, high-efficiency, and low-temperature energy storage systems. The membrane-based reactor offers a large specific surface area and integrates solution/refrigerant flows, which enables formation of a highly compact reactor exhibiting strong heat/mass transfer. In some embodiments, direct diffusion of water molecules through the membrane makes it possible to lower the required charging temperatures.

摘要： The present invention provides a heat pump that includes an absorber/evaporator module having a solution channel and a refrigerant channel along with first and second liquid channels. A porous membrane is positioned between the refrigerant channel and the solution channel; the porous membrane permits flow of vapor molecules therethrough while restricting flow of absorbent molecules. A membrane-based generator/condenser module with a similar structure is in fluid communication with the absorber/evaporator module. The membrane-based modules offer a large specific surface area with integrated solution/refrigerant flows, which enables formation of a highly compact heat pump exhibiting strong heat/mass transfer.
