| Research Abstract |
To improve a cold output from water sorption refrigerators, we focused on sorption materials, and examined HDACF(High-Density Activated Carbon Fiber) and/or CaCl_2/HDACF composite sorbent for preparation procedures, water sorption performances and heat transfer enhancement. Experimental results showed that HDACFs with various apparent densities could be obtained from phenolic fibers by a hot-briquetting, carbonization and activation treatments. CaCl_2/HDACFs, which were easily prepared by a solution impregnation method, have superior water sorption performance in the lower vapor pressure range. HDACF could be combined with aluminum materials such as fine wires, wire mesh and fine particles. These results indicated that HDACF or CaCl_2/HDACF composite sorbent would be promising materials for high efficiency water sorption refrigerators.
