摘　　要：设计了连续而又稳定循环的三效吸附式热泵单元——三效冷环。由于各吸附床的吸附循环之间具有先后连贯性，因此既避免了吸附床的过热，又消除了热泵输出端的不稳定工作状态，使得热泵系统的ＣＯＰ值、火用效率以及各吸附循环的效率比双效和单效系统均有显著提高。注重分析了回收和不回收降温、吸附热时，三效吸附式热泵与其它系统相比的优越性。In this paper the design concept of a tri coupled cycle adsorption heat pump unit is proposed under the thermodynamic analysis. Due to the three adsorption beds designed working in series, the heat pump will have the advantages of avoiding overheating of adsorption beds and eliminating the unsteady out put so as to improve the COP and the efficiency of each adsorption cycle. The advantages of adsorption heat pump under two kinds of working conditions, with and without recovery of cooling and adsorption heat are analysed in this paper.
