该研究研究了具有能量级联的四床硅胶-水质量回收吸附制冷循环的性能。在吸附式制冷循环中，吸附器和解吸器中的压力不同。质量回收循环利用压力差来增强制冷剂质量循环。所提出的周期具有三个主要特点； (1) 该循环由两个单级循环组成。 (2) 热水和冷却水均采用单级循环，级联。 (3)一个循环的吸附器/解吸器换热器与另一循环的另一吸附器/解吸器换热器连接。通过循环模拟计算机程序计算比冷却功率（SCP）和性能系数（COP），以分析运行条件的影响。所提出的循环与单级循环在 SCP 和 COP 方面进行了比较。结果表明，所提出的冷冻水循环的SCP和COP优于传统的单级循环，并且所提出的循环在低热源温度下具有很大的优势。
The study investigates the performance of a four-bed, silica gel–water mass recovery adsorption refrigeration cycle with energy cascading. In an adsorption refrigeration cycle, the pressures in adsorber and desorber are different. The mass recovery cycle utilizes the pressure difference to enhance the refrigerant mass circulation. Proposed cycle has three main characteristics; (1) The cycle consists of two single-stage cycles. (2) Hot and cooling water is used in each single-stage cycle with cascading. (3) Adsorber/desorber heat exchanger of one cycle is connected with another adsorber/desorber heat exchanger of other cycle. Specific cooling power (SCP) and coefficient of performance (COP) were calculated by cycle simulation computer program to analyze the influences of operating conditions. The proposed cycle was compared with the single-stage cycle in terms of SCP and COP. The results show that SCP and COP of proposed cycle with cascading chilled water are superior to that of conventional, single-stage cycle and the proposed cycle has high advantage at low heat source temperature.
