Abstract

Energy saving and reduction in the green house gas emissions are key to the growth of the economy of a country. The study's objective is to develop a solar-powered cascade refrigeration system. The solar assisted cascade system is the combination of electricity-powered conventional vapour compression refrigeration system (VCRS) and solar-powered vapor absorption refrigeration system (VARS), connected in series. The system performance is analysed based on the solar thermal energy potential available at Riyadh region of the Kingdom of Saudi Arabia (KSA). NH3 − H2O mixture is used in VARS and three different refrigerants of highest performance are selected for VCRS. Thermal Energy Storage (TES) is used to store potential energy to keep the system operating round the clock continuously. The results indicate that the coefficient of performance (COP) of the proposed system is superior compared to the conventional VCRS and has a 44.7% saving in electrical energy consumption during peak load demands. It is notice...

沙特利雅得地区太阳能梯级制冷系统制冷性能及节能分析

节约能源和减少温室气体排放是一个国家经济发展的关键。这项研究的目标是开发一种太阳能级联制冷系统。太阳能辅助梯级制冷系统是由电力驱动的传统蒸汽压缩制冷系统(VCRS)和太阳能蒸汽吸收制冷系统(VARS)串联而成的。根据沙特阿拉伯王国(KSA)利雅得地区可用的太阳能热能潜力对系统性能进行了分析。VCRS采用NH3−H2O混合物，VCRS选用了三种性能最高的制冷剂。热能储存(TES)用于储存势能，以保持系统全天候连续运行。结果表明，该系统的性能系数(COP)优于传统的VCRS，在峰值负荷需求下可节省44.7%的电能消耗。这是通知……
