本文提出了一种新型太阳能吸附制冷系统的设计，该系统具有两个相同的小吸附床和一个大吸附床，可以连续生产冷量。在该系统中，冷能在环境温度下以制冷剂的形式储存在单独的制冷剂储存罐中。硅胶-水作为工作对，系统由太阳能驱动。详细阐述了其工作原理，并对其进行了热力学暂态分析。讨论了不同吸附剂质量和小床吸附/脱附时间对COP和SCE的影响。讨论了在发电温度为368K，冷凝器温度为303K，蒸发器温度为283K时，较小床层实现连续冷却的推荐质量和循环次数，平均COP和SCe分别为0.63kJ/kg和337.5 kJ/kg。
In this paper, the design of a new solar operated adsorption cooling system with two identical small and one large adsorber beds, which is capable of producing cold continuously, has been proposed. In this system, cold energy is stored in the form of refrigerant in a separate refrigerant storage tank at ambient temperature. Silica gel–water is used as a working pair and system is driven by solar energy. The operating principle is described in details and its thermodynamic transient analysis is presented. Effect of COP and SCE for different adsorbent mass and adsorption/desorption time of smaller beds are discussed. Recommended mass and number of cycles of operation for smaller beds to attain continuous cooling with average COP and SCE of 0.63 and 337.5 kJ/kg, respectively are also discussed, at a generation, condenser and evaporator temperatures of 368 K, 303 K and 283 K, respectively.
