2、间内。最后，计算了个工质对的制冷量，通过对各工质对的平衡吸附及解吸的研究，及安全因素的考虑，选定R123．活性炭作为新型流态化吸附制冷系统的吸附工质对。最后，将工质对应用到流态化吸附制冷系统中进行实验研究。测得了不同温度条件(包括：蒸发温度、吸附温度、解吸温度和冷凝温度)下的吸附量和解吸量。利用得到的实验数据对新型吸附制冷系统的性能进行了分析和计算。通过分析，建立了吸附热与吸附量之间的函数关系式。同时，计算得到了新型吸附制冷系统的SCP，通过比较发现，新型吸附制冷系统的SCP要远高于传统的间歇式吸附制冷系统的。关键词：低品位热源，吸附质冷，自然工质，R123，13X分子筛，活性炭，热天平，流化
