Abstract: A system comprises an electrochemical liquid desiccant regeneration system, a first air contactor, and a second air contactor. The regeneration system comprises a first output stream having a first concentration of liquid desiccant and a second output stream having a second, lower concentration. The first air contactor disposes a first input air stream having a first water concentration in fluid communication with the first output stream to form a first output air stream having a second, lower water concentration and a diluted output stream, which is circulated back into the regeneration system. The second air contactor disposes a second input air stream having a third water concentration in fluid communication with the liquid desiccant output stream to form a second output air stream having a fourth water concentration higher than the third water concentration and a concentrated output stream, which is circulated back into the regeneration system.

Abstract: A solution flows through a salinate chamber and a desalinate chamber of an electrochemical cell. Solutes are moved from the desalinate chamber to the salinate chamber to create respective solvent and concentrate streams from the desalinate and salinate chambers. The concentrate stream flows to a recombination cell where it is combined with a solvent. The combination causes at least one of an absorption of heat within the recombination cell and emission of heat from the recombination cell.

Abstract: A system comprises an electrodialysis apparatus, which includes first and second reservoirs, wherein a salt concentration in the first reservoir reduces below a threshold concentration, and salt concentration in the second reservoir increases during an operation mode. A first electrode comprises a first solution of a first redox-active electrolyte material, and a second electrode comprises a second solution of a second redox-active electrolyte material. In a first reversible redox reaction between the first electrode and first electrolyte material at least one ion is accepted from the first reservoir, and in a second reversible redox reaction between the second electrode and second electrolyte material at least one ion is driven into the second reservoir. A first type of ion exchange membrane is disposed between the first and second reservoirs, and a second type of ion exchange membrane, different from the first type, is disposed between the respective electrodes and reservoirs.

Abstract: A system includes an electrochemical regenerator configured to receive a first solution having a first salt concentration and output a second solution having a second salt concentration lower than the first salt concentration and a third solution having a third salt concentration higher than the first salt concentration. The first and second solutions are sent to first and second reservoirs respectively absorb and emit heat in response to a phase change of one of the solutions. The absorption or emission of heat can be used in a heat pump system.

Abstract: An electrochemical system has a first reservoir receiving a feed stream. The feed stream includes a solvent and a solute different than the salt. A second reservoir receives a brine stream with a higher salt concentration higher than the feed stream. Electrodes contact a loop of redox-active electrolyte material causing reversible redox reactions. The reactions cause the loop to accept a first ion from the salt in the first reservoir and drive a second ion into the brine stream in the second reservoir. Three ionic exchange membranes of alternating type define the first and second reservoirs. A concentrate stream is output from the first reservoir, the concentrate stream having a second solute concentration greater than the first solute concentration.
