SrCl2-NH3化学吸附式制冷工质对吸附特性的研究

摘要

A study on the adsorption characteristics of the chemisorptionrefrigeration working pair using SrCl2 as adsorbent and NH3 as refrigerant was performed.The adsorption isotherms were obtained，the adsorpt i on isotherm equations were fit and the chemisorption mechanisms were discussed.T he results showed that SrCl2-NH3 is an excellent working pair in its larg e adsorption refrigeration capacity per unit weight of adsorbent and suitable fo r solar energy and low grade waste heat.%对以SrCl2为吸附剂、NH3为致冷剂所组成的化学吸附式制冷工质对的吸附性能进行了研究，得到了吸附等温线、回归出吸附等温方程并对化学吸附过程机理进行了探讨。研究结果表明，SrCl2-NH3工质对的吸附制冷量大，适宜太阳能或低品位余热驱动，是性能优良的工质对。
