A two-bed adsorption refrigeration cycle (ARC) with a new proposed modified mass recovery process is investigated (modeled, optimized and compared with ARC cycle with conventional mass recovery process) here. This proposed modified mass recovery process increases the system cooling capacity and cycle exergy efficiency. These achievements reached by opening the connecting valve between two beds during mass recovery process as usual, but continuing cooling of adsorption bed by water even during mass recovery process. Thus, the refrigerant vapor moved from desorber to adsorber bed in this situation by two effects, the higher pressure of refrigerant vapor in desorber bed and also due to higher effect of adsorption process for cooling of this bed by water. Furthermore, at the end of the proposed modified mass recovery process, the equilibrium pressure of beds was closer to the evaporator pressure than that for ARC with conventional mass recovery process. Thus, the new switched adsorption bed could connect to evaporator even during pre-cooling process. This makes connecting time period of evaporator and adsorber longer than that for ARC with the conventional mass recovery process. The above effects increased the amount of refrigerant vapor adsorbed in the adsorption bed which increased ARC cooling capacity as well. Finally to study the effects of various design variables, a two bed ARC with the proposed modified mass recovery cycle is modeled and optimized for a specific cooling capacity by considering coefficient of performance and exergy destruction as two objective functions. Results for a system with 14 kW (4 refrigeration tons) cooling capacity showed 0.555, 0.284 and 1719.6 kJ for optimum values of coefficient of performance (COP, with 0.9% increase), exergy efficiency (14% increase) and total exergy destruction (16.2% decrease), respectively in comparison with those for ARC with the conventional mass recovery process.

此处研究了具有新提出的改进质量回收过程的双床吸附制冷循环 (ARC)（建模、优化并与具有传统质量回收过程的 ARC 循环进行比较）。该提议的改进的质量回收过程增加了系统冷却能力和循环火用效率。这些成就是通过像往常一样在质量回收过程中打开两个床之间的连接阀，但即使在质量回收过程中也继续用水冷却吸附床来实现的。因此，在这种情况下，制冷剂蒸气通过两个作用从解吸器移动到吸附器床，解吸器床中制冷剂蒸气的压力较高，并且还由于吸附过程通过水冷却该床的较高效果。此外，在拟议的改进质量回收过程结束时，与传统质量回收工艺的 ARC 相比，床的平衡压力更接近蒸发器压力。因此，即使在预冷过程中，新的切换吸附床也可以连接到蒸发器。这使得蒸发器和吸附器的连接时间比传统质量回收工艺的 ARC 更长。上述效果增加了吸附在吸附床中的制冷剂蒸汽量，这也增加了 ARC 冷却能力。最后，为了研究各种设计变量的影响，通过将性能系数和火用破坏作为两个目标函数，对具有所提出的改进的质量回收循环的双床 ARC 进行建模和优化，以实现特定的冷却能力。具有 14 kW（4 制冷吨）冷却能力的系统的结果显示为 0.555，0。
