Abstract

Adsorption cooling system is a promising technology that can be used to exploit the abundant amount of low grade heat sources such as solar energy, geothermal and waste heat from industrial processes. This technology can be more useful in the hot and developing countries where millions of people face annually the severe heat waves during summer and they still lack access to secure electricity grids, where adsorption system can be used to generate electricity as well as cooling in the same time. In this study, a novel four bed adsorption system is designed to generate cooling and electricity simultaneously. The system comprises mainly of two topping beds, two bottoming beds, two evaporators, condenser and expander (turbine). The topping beds are powered using the low grade heat source and utilizing AQSOA-Z02 (SAPO-34) zeolite (an advance adsorption material) and water, while the bottoming beds is powered by the heat recovered from the topping beds and utilizing Silica-gel and water. Results show that the overall system efficiency can be improved by 62%.

新型吸附冷却和发电系统，利用低品位热源

吸附冷却系统是一种很有前途的技术，可用于开发大量的低品位热源，如太阳能、地热和工业过程中的废热。这项技术在炎热的发展中国家可能更有用，在这些国家，每年有数百万人在夏季面临严重的热浪，而且他们仍然无法获得安全的电网，在那里，吸附系统可以同时用于发电和冷却。在这项研究中，设计了一种新型的四床吸附系统，同时产生冷却和电力。该系统主要由两个顶床、两个底床、两个蒸发器、冷凝器和膨胀器(涡轮)组成。顶床采用低品位热源，利用AQSOA-Z02 (SAPO-34)分子筛(一种高级吸附材料)和水作为动力;底床采用顶床回收的热量，利用硅胶和水作为动力。结果表明，系统整体效率可提高62%。
