Patent 11925903 was granted and assigned to Xerox on March, 2024 by the United States Patent and Trademark Office.
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.
