This work describes the development of Metal Organic Frameworks based adsorption system for producing ice, cooling, ice slurry and potable water using a nickel based coordination polymer with open metal sites of organic frameworks and sea water as working pair. In this system, cooling is generated due to the evaporation of the refrigerant caused by the adsorption process. This cooling is used to produce solid pure ice, ice slurry (sea water) and chilled water. The system will also produce desalinated water from the condensation of the water vapour desorbed during the desorption process. The effect of number of cycle, switching time, adsorption/desorption time and salinity of saline water on the performance of the adsorption system in terms of coefficient of performance, specific daily production of ice, slurry mixture and fresh water were investigated. Results showed that with number of cycles, switching time, adsorption/desorption time and salinity were found as up to 3 cycles, 3 min, 15 min and 35,000 ppm, the maximum ice production, 8.9 ton/day/ton_ads at generation, chilled antifreeze and ambient temperature of 95 degrees C, -1 degrees C and 24 degrees C, respectively.
