Adsorption ice making and freeze water desalination using Metal Organic Framework materials

摘要

This work presents a novel adsorption system for producing ice and potable water using fresh and saline water as refrigerants and Metal Organic Framework material (CPO-27Ni) as adsorbent. In this work, an advanced technique of adsorption ice making integrated with vacuum direct freeze desalination is developed. The effect of fresh water specific volume in the evaporator and the performance of this system in terms of coefficient of performance (COP), specific daily production of ice (SDIP), slurry mixture (SDSP) and fresh water (SDWP) were experimentally investigated. The optimum COP was up to 0.205 whereas 10.5, 29.5 and 1.32 ton/day/ton of adsorbent for SDIP, SDSP and SDWP, respectively. The results are obtained at generation temperature of 95°C, antifreeze temperature of -1°C and fresh water of 450ml.
