一种有潜力的吸附式制冷工作对——活性炭纤维-甲醇

A POTENTIAL SOLID ADSORPTION REFRIGERATION PAIR ——ACTIVE CARBON FIBER METHANOL

吸附式制冷具有无ＣＦＣｓ问题、可利用低品位热能驱动、价格效用比高等一系列优点。由于一般吸附剂吸附／解吸时间长和单位质量制冷功率小使吸附式制冷的产品化受阻。活性炭纤维是一般吸附剂活性炭的较好替代物，其对甲醇的吸附容量为活性炭的２—３倍，而吸附／解吸时间仅为活性炭的１／１０左右。对紧凑式吸附式冰箱，活性炭纤维－甲醇是一种好的工作对。

Although adsorption refrigeration has the advantages like non CFCs problems can be driven by low grade heat energy,and cost effective if compared with normal vapor compression systems,the real applicable machine is still on the way of research as the adsorption/desorption time is usually long and the refrigeration power density per unit mass of adsorbent small However active carbon fiber(ACF)might be a good substitute for active carbon(AC)adsorbent,the experiments show that the adsorption capacity of ACF on methanol is 2 to 3 times of that of AC on methanol,and the adsorption/desorption time of ACF is just about 1/10 of that of AC ACF methanol is a potential solid adsorption refrigeration pair for the development of compact household adsorption refrigerator
