摘　　要：对新型化学吸附式制冷工质对CoF_2-NH_3的吸附特性进行了实验研究,得出了吸附等温线,研究结果表明,CoF_2-NH_3工质对的单位吸附量大,达到最大吸附量时的温度要求降低,吸附周期缩短,并且多次重复吸附后既不结块,也不膨胀,为化学吸附式制冷的小型化和实用化提供了新的可能性。A study on the adsorption characteristics of the chemisorption refrigeration working pair of CoF2 and NH3 was performed, and the adsorption isotherms was obtained. The results show that CoF2-NH3 is an excellent working pair in its large adsorption capacity, low temperature required and short adsorption cycle time. In addition, agglomeration and expandability was not found after 10 times adsorption. It is shown that the miniaturization and practicability of chemisorption refrigeration is feasible.
