基于太阳能的多能源互补供热装置的研究与开发
|
摘要
太阳能等可再生能源供暖是清洁取暖的重要方式,单一可再生能源难以获得较高的贡献率和供暖稳定性。本文研究并开发一种基于太阳能的多能源互补供热装置,试制了样机并进行了应用。基于Trnsys软件构建装置模型并利用实测数据进行了验证,利用模型对装置在节能住宅中的应用效果进行了分析,与现有的太阳能供暖系统相比,采用本装置系统的有用得热量提升75%,太阳能保证率由10%~20%提升至41.2%,若集热器面积增加一倍,系统的太阳能保证率可达70%。
The application of renewable energy,solar energy included is important way to realize clean heating. It is difficult to acquire higher contribution rate and keep space heating steadily with one single renewable energy. In this paper,a multi-energy complementary heating device based on solar energy is investigated. The prototype has been set up and applied in a building. The computational model is established with Trnsys and verified by measured data,and with the model,the analysis of the device application in energy-saving residential house was performed.The results reveal that,compared with the existing solar heating systems,the useful heat gain is increased by 75%and solar fraction is increased from 10% ~ 20% to 41. 2%. When the area of solar collectors is doubled,solar fraction will reach to 70%.
