  • Patent number: 11331628
    Abstract: A membrane evaporative condenser (MEC) includes a repeating sequence of channels for evaporation and/or condensation are arranged, each sequence of channels includes a condensation channel for condensation of a vapor to a liquid, an evaporation channel, and zero to one hundred evaporation-condensation channels. The condensation channel has walls of a non-permeable material which exterior to the condensation channel share the wall with a liquid evaporative medium (LEM) conduit that contains a LEM. The LEM conduit includes a moisture transfer membrane (MTM), where the LEM can evaporate into an evaporation channel or an evaporation-condensation channel that can amplify the effect of the heat transfer for additional mass transfer.
