摘　　要：针对现有吸附式热泵应用研究中单组分循环工质对操作压力过高或过低的现状 ,提出一种新型的混合吸附工质对———分子筛、水和氨 ,构成耦合吸附吸收 (ADAB)系统。实验研究发现 :ADAB系统可在接近大气压环境下实现吸附解吸循环 ,为吸附式热泵系统工业化可行性提供条件。通过实验分析讨论了影响ADAB系统性能的结构参数及操作参数 。In traditional adsorption cycle, working fluid is limited to select single component. As a result, the working pressure is far digressed from ambient pressure. The cost is high to run this kind of vacuum or high- pressure system. Based on generalizing the adsorption cycle and absorption cycle, a new type of refrigeration cycle coupled with adsorption and absorption is developed (ADAB cycle). In the new ADAB system, ammonia and water are chosen as refrigerants, and zeolite as adsorbent. The evaporation pressure and the condensation pressure can approach to a moderate pressure. The new system shows a new way to make the adsorption refrigeration pump practicably. Optimum analysis and some characters are also discussed.
