  • Liquid to air membrane energy exchangers
    Patent number: 10712024
    Abstract: A liquid to air membrane energy exchanger (LAMEE) can be used as part of a heating and cooling system to transfer heat and moisture between a liquid desiccant and an air stream to condition the temperature and humidity of the air flowing through the LAMEE. The membrane can be a non-porous film having selective permeability for water, but not for other constituents that form the liquid desiccant. The non-porous membrane can allow for use of liquid desiccants, such as glycols, that had been previously determined to be unacceptable or undesirable in these types of applications. In an example, the membrane can be an ion-exchange membrane or pervaporation membrane.
