Abstract
A high performance ADSorption Heat eXchanger ADS-HX includes a hygroscopic composite biopolymer, a heat exchange medium in contact with the hygroscopic composite biopolymer and a hollow conduit in contact with the heat exchange medium, into which hollow conduit either a cooling fluid or a heating fluid are alternately made to pass, so that the adsorption heat exchanger can be operated under high ambient temperatures and low relative humidity conditions, which are typical of arid climates. A process is provided for producing the aforesaid high performance ADSorption Heat eXchanger ADS-HX. A preferred and advantageous application of the aforesaid high performance ADSorption Heat eXchanger ADS-HX is in combination with the atmospheric water harvesting device described in the international application published at no. WO 2019/082000 A1 of the same Applicant.
