Abstract
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.
