一种新型太阳能空气集热器的热性能研究
|
摘要
太阳能作为一种可再生能源,清洁且资源丰富。开发利用太阳能有着巨大的社会效益和环境效益。
本文首先介绍了太阳能集热器的研究现状和发展趋势,对现有的各种太阳能空气集热器的特点进行了分析比较。并在本课题组提出的冲缝型吸热板理念的基础上,研究了一种采用冲缝型吸热板加真空玻璃盖板的新型太阳能空气集热器,该集热器属于渗透型平板太阳能空气集热器,具有很高的集热效率。
为此,本文首先设计了新型太阳能空气集热器的实验模型,进行了动态实验,对模型使用普通玻璃盖板与真空玻璃盖板两种情况下的热性能进行了对比分析,并对集热器效率的影响因素进行了实验研究。接着对新型太阳能空气集热器的传热过程建立了数学模型,使用Matlab软件对模型进行求解。并通过实验结果与模拟结果的对比分析,验证了数学模型的准确性。在此基础上,本文对新型太阳能空气集热器进行了数值模拟计算,对不同工况下的集热器的热性能进行了对比分析,并研究了在冬季工况下集热器高度、空气流量以及太阳辐射强度等因素对新型太阳能空气集热器集热效率的影响。
最终本文得出结论:采用冲缝型吸热板加真空玻璃盖板的新型太阳能空气集热器具有很高的集热效率,可以与建筑紧密结合,满足建筑冬季和过渡季采暖通风要求,也可以用在物料干燥方面,是一种较好的可再生能源热利用方式,具有进一步深入研究和应用的价值。
As a renewable energy source, solar energy is c lean and resourceful. Exploting and utilizing solar energy has immense social an economic benefit.
In this article, we first introduce the development of solar air collector, and make a comparison of mast kinds of solar air collectors. So I make some improvements in the ideas designed by my team members and develop a novel solar air collector with plane vacuum glazing and punching seams in absorber, which is high efficiency.
Then we designed a novel type of collector and investigated this kind of collector model with or without vacuum glass by dynamic experiment, analysed the influencing factors of solar air collector, and obtained the performance parameter of the collector to verify the accuracy and reliability of the mathematical model. Then we set up the mathematical model of the new type high efficient solar air collector, and make a theoretical analysis on its heat exchange stituation and performance. On that basis, we take on a numerical simulation on the novel solar air collector. We investigate the collection efficiency of the collector under different height, air volume, as well as factors such as radiation intensity, and make a comparative analysis to the performance under the same size and different working condition.
It is a conclusion through the research that the novel type of solar air collector is intergraded very well with building and have good act in heating and ventilating in winter and a transitional season, as well as drying affect on materia. It is a better use of the heat and have a value for in-depth study and application.
