摘要

在本文中，在一个装有a型硅胶的吸附室中，成功地验证了一个集成了用户定义功能的太阳能驱动吸附冷却系统（UDF）的三维全模拟模型。该模型在解吸阶段进行了验证，最大偏差误差为1.7%。显示了带有吸附轮廓的温度，以更好地理解热流在室内具有全方位的吸附行为。脱附阶段的最高温度在翅片区域300秒后达到，并且在翅片壁处吸附最大吸收达到0.16千克/千克，但在翅片区域周围达到0.13至0.14千克/公斤。在吸附过程结束时，平均吸附量达到0.136。在整个循环时间内，制冷剂质量为1.8kg时，吸附和解吸之间的最终吸收量为0.018kg/kg。

Three Dimensional CFD Simulation Model with Experimental Validation of Silica Gel–Water Pair Adsorption Cooling Bed

In this paper, a three-dimensional full simulation model of a solar-driven adsorption cooling system integrated with user-defined functions (UDF) is successfully validated with a manufactured adsorption chamber filled with silica-gel type A. model is validated on the desorption phase with a maximum deviation error of 1.7%. Temperature with adsorption contours are shown for more understanding of the heat flow with adsorption behaviour inside the chamber in all directions. The maximum temperature at the desorption phase is reached after 300 seconds at fins area, and adsorption maximum uptake reached 0.16 kg/kg at fins wall but reached from 0.13 to 0.14 kg/kg around fins area. The average adsorption uptake reached 0.136 at the end of the adsorption process. The resultant uptake between adsorption and desorption is 0.018 kg/kg with a refrigerant mass of 1.8 kg in a complete cycle time.

期刊介绍： WSEAS Transactions on Power Systems publishes original research papers relating to electric power and energy. We aim to bring important work to a wide international audience and therefore only publish papers of exceptional scientific value that advance our understanding of these particular areas. The research presented must transcend the limits of case studies, while both experimental and theoretical studies are accepted. It is a multi-disciplinary journal and therefore its content mirrors the diverse interests and approaches of scholars involved with generation, transmission & distribution planning, alternative energy systems, power market, switching and related areas. We also welcome scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations.
