Abstract

The sizing of a solar thermal system to feed the water distillers in the laboratory of the Santander Technological Units is presented, proposing a comparative study between three calculation methods (f-chart, instantaneous and ACSOL) for the estimation of the surface of solar capture, finally supported by modeling in the TRNSYS software of the final system, to evaluate its behavior dynamically during one year. Initially, a search for information is carried out to establish the models to develop each of the calculation methods, additionally technical data is collected from the laboratory equipment to determine the consumption of hot water. Subsequently, each of the calculation methods is applied in order to size the catchment surface, to finally carry out a comparative study between the results obtained, determining which is the most appropriate method for the calculation and defining the dimensions of the same, to develop a modeling of the dynamic behavior of the system through the TRNSYS Software. The final result presents a storage system with an average temperature of 62.13 ° C and solar collectors with an average temperature of 58.7 ° C for one year of operation. Finally, the operating time of the resistive stills is reduced from 11 hours a day to 6 hours with the integration of the Thermosolar system.
利用 TRNSYS 对作为电阻水蒸馏系统供电替代方案的太阳能热系统进行建模
本文介绍了为桑坦德技术大学实验室的蒸馏水器供水的太阳能热系统的选型,提出了三种计算方法(f-图表法、瞬时法和 ACSOL 法)之间的比较研究,以估算太阳能捕获表面,最后通过 TRNSYS 软件对最终系统进行建模,动态评估其一年的行为。首先,需要搜索相关信息,以建立模型来开发每种计算方法,此外,还需要从实验室设备中收集技术数据,以确定热水消耗量。随后,应用每种计算方法确定集水面的大小,最后对所获得的结果进行比较研究,确定哪种方法最适合计算,并确定相同的尺寸,通过 TRNSYS 软件建立系统动态行为模型。最终结果显示,蓄能系统的平均温度为 62.13 摄氏度,太阳能集热器的平均温度为 58.7 摄氏度,运行时间为一年。最后,整合 Thermosolar 系统后,电阻式蒸馏器的运行时间从每天 11 小时减少到 6 小时。
