摘　　要： 用 CaCl ₂( 钙氯化物) 的一个热地驾驶的吸附冰箱 /AC (激活的碳) 合成吸附物被开发了。通过最佳的设计，更少阀门被使用，颤动和噪音被降低，并且吸附床的尺寸被减少即，吸附冰箱是更紧缩的。冰箱的表演被测试，并且试验性的结果证明冷却能力，警察(性能的系数)， SCP (特定的冷却力量每吸附物的公斤)，并且 VCD (体积冷却密度)分别地等于 3.74 kW ， 0.26 ，在加热温度， 28 °C 冷却水温度，和 −12.5°C 蒸发温度的 140 °C 的条件下面的 440.0 W kg ⁻¹和 69.73 kWm ⁻³。系统的动态特征在系统性能上象解吸附作用行动和集体恢复过程的明显的 eff ects 一样在温度和压力显示了轮转的变化。同时，试验性的结果证明系统的表演能被更高的加热温度，集体恢复过程，和集体恢复时间的吸附 / 解吸附作用时间的合理比率显著地改进。 A thermally driven adsorption refrigerator using CaCl2 (calcium chloride)/AC (activated carbon) composite adsorbent has been developed. Through the optimal design, fewer valves are used, the vibration and noise are lowered, and the size of the adsorption bed is decreased, i.e., the adsorption refrigerator is more compact. The performance of the refrigerator is tested, and the experimental results showed that the cooling capacity, COP (coeffi cient of performance), SCP (specifi c cooling power per kilogram of adsorbent), and VCD (volume cooling density) are equal respectively to 3.74 kW, 0.26, 440.0 W kg-1 and 69.73 kW·m-3 under the conditions of 140°C heating temperature, 28°C cooling water temperature, and -12.5°C evaporation temperature. The system's dynamic characteristics indicated the cyclical variations in temperature and pressure as well as the obvious eff ects of desorption action and mass recovery process on the system performance. Meanwhile, experimental results showed that the performance of the system can be improved signifi cantly by the higher heating temperature, mass recovery process, and the reasonable ratio of the adsorption/desorption time to the mass recovery time. © 2015 by Begell House, Inc.
