Abstract A novel design is proposed that couples an evacuated tube solar collector and adsorption cooling system in one module, namely, an evacuated tube solar adsorption cooling module. The module is basically a simple adsorption cooling system placed inside an evacuated glass tube with a length of about 180 cm, and an internal diameter of 5.5 cm. One side (top section of the tube) represents the adsorbent bed (generator) and contains the adsorbent, while the other side (bottom section of the tube) represents the condenser/evaporator and contains the refrigerant. In this paper, the module was investigated experimentally to find its optimal adsorbent bed design and results show that the system is promising from energy and cost point of views. Zeolite 13X was examined and it shows an excellent adsorption rate which gives it an advantage over other adsorbents for cooling applications. Additionally, the solar COP of the evacuated tube adsorption cooling module was experimentally evaluated to be 0.15. Cost analysis displayed that our proposed system is comparable with vapor compression systems driven by solar PV.

真空管太阳能吸附冷却模块的实验研究及吸附床优化设计

摘要 提出了一种将真空管太阳能集热器和吸附冷却系统耦合在一个模块中的新型设计，即真空管太阳能吸附冷却模块。该模块基本上是一个简单的吸附冷却系统，放置在一个长约 180 厘米、内径为 5.5 厘米的真空玻璃管内。一侧（管的顶部）代表吸附床（发生器）并包含吸附剂，而另一侧（管的底部）代表冷凝器/蒸发器并包含制冷剂。在本文中，对该模块进行了实验研究，以找到其最佳吸附床设计，结果表明该系统从能源和成本的角度来看是有前途的。对沸石 13X 进行了测试，它显示出优异的吸附速率，这使其在冷却应用中优于其他吸附剂。此外，真空管吸附冷却模块的太阳能 COP 经实验评估为 0.15。成本分析表明，我们提出的系统可与太阳能光伏驱动的蒸汽压缩系统相媲美。
