摘　　要：报导采用管式结构的氯化钙－氨吸附／脱附过程传热特性试验台．试验结果表明ＣａＣｌ２对ＮＨ３的吸附／脱附化学反应对ＣａＣｌ２－ＮＨ３介质的传热机理有较大影响．A test for investigating the heat transfer characteristics of a hollow cylinderical packedbed of CaCl2·nNH3(n=2,4) in the adsorption and desorption processes is presented. Theexperimental results show that the chemical reactions in adsorption and desorption processeshave a great effect on the heat transfer mechanism in the CaCl2·nNH3 medium. A model isextablished to describe the heat transfer in the CaCl2·nNH3 packed bed in adsorption anddesorption proceses.
