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.

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.
