A dehumidification system for removing water vapors from an air is disclosed. The system includes a dehumidification core defining an air channel and at least one vapor channel separated from the air channel by a membrane to facilitate a removal of moisture from the air flowing through the air channel and is selectively permeable to water and water vapor and impermeable to air. The dehumidification system further includes a water ejector having a throat portion fluidly coupled to the vapor channels and adapted to create a relatively lower pressure of water vapor within the vapor channels than in the air channel The water ejector also includes an outlet portion disposed downstream of the throat portion and configured to increase the pressure of water to facilitate a condensation of the water vapors received from the vapor channels.

Dehumidification system

An air-cooling system includes an evaporator adapted to cool an air and a reservoir for storing a liquid and providing the liquid to the evaporator. The air-cooling system also includes a pressure reducer system fluidly coupled to the evaporator and adapted to create a relatively low pressure inside the evaporator to facilitate a conversion of the liquid flowing through the evaporator into vapors. The pressure reducer system includes a liquid ejector having an inlet portion adapted to receive the liquid from the reservoir, a throat portion arranged downstream of the inlet portion and fluidly coupled to the evaporator and an outlet portion disposed downstream of the throat portion and configured to increase a pressure inside the liquid ejector. The pressure reducer system also includes a pump fluidly connected to the liquid ejector and the reservoir to supply the liquid from the reservoir to the liquid ejector.

Air-cooling system

An air conditioning (AC) system is provided, employing a sulfonated copolymer (SC) layer as a selectively permeable and ion exchanging membrane. The sulfonated block copolymer has an IEC greater than 0.5 meq/g. In embodiments, the sulfonated block copolymer is used to form the membrane itself, or bonded/coated onto a membrane or a foam. In embodiments, the AC employs a membrane electrode assembly, i.e., using electric field across a membrane in a dehumidifier to transport moisture generating a dry air stream, along with an evaporative cooler for latent heat removal via evaporation induced cooling of the dry air stream from the dehumidifier. The system operates as a closed loop wherein the room air after cooling is recycled or loop back to the dehumidifying membrane electrode assembly to generate dry air for the evaporative cooler, generating conditioned air.
