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。 A three-effect adsorption heat pump unit, a three-effect cold ring, is designed for continuous and stable circulation. Because of the continuity between the adsorption cycles of each adsorption bed, overheating of the adsorption bed is avoided, and the unstable working state of the heat pump output is eliminated, so that the COP value, the exergy efficiency, and the efficiency of each adsorption cycle of the heat pump system Compared with double-effect and single-effect system have significantly increased. Focus on the analysis of the recovery and non-recovery of cooling, adsorption heat, three-way adsorption heat pump compared with other systems superiority.
