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.

为了改善吸水冰箱的冷输出，我们专注于吸附材料，并检查了HDACF（高密度活化的碳纤维）和/或CACL_2/HDACF复合材料，以进行制备程序，吸附性能和热传递增强。实验结果表明，通过热爆炸，碳化和激活处理，可以从酚类纤维中获得各种明显密度的HDACF。 CACL_2/HDACF可以通过溶液浸渍方法轻松制备，在较低的蒸气压范围内具有出色的水吸附性能。 HDACF可以与铝材料（例如细丝，电线网和细颗粒）结合使用。这些结果表明，HDACF或CACL_2/HDACF复合吸附剂将是高效率水吸附冰箱的有前途的材料。
