Experimental investigation of MOF adsorption system for ice making, freeze water desalination and cooling applications

This work describes the development of Metal Organic Frameworks based adsorption system for producing ice, cooling, ice slurry and potable water using a CP0-27(Ni) and potable/sea water as working pair. Also a novel vacuum based direct freezing technique has been developed in the evaporator of the adsorption ice making system. In this new technique, cooling is generated in the evaporator to produce three outputs, namely, ice, ice slurry and cooling by lowering the freezing point of water using sea salt. The ice and ice slurry are produced in the evaporator during the adsorption-evaporation process, while the cooling process is produced by circulating the water/antifreeze to be cooled in the evaporator. Moreover, the usage of seawater as refrigerant offers producing fresh water as a fourth output in the condenser. A Single and a double bed CP0-27(Ni) MOF adsorption systems were developed to investigate the effect of this novel technique on the system performance in terms of producing of the four outputs. Compared to published literature, the proposed technology showed significantly higher Specific Daily Ice Production of 3 times those reported in literature with additional outputs of ice slurry, cooling and distilled water.
