摘要
基于实验测试、数学模拟、模型分析等方法,介绍了国内外全玻璃真空管太阳能集热器的研究现状和发展趋势。分析各影响因素对集热效率的影响,确定最佳倾角,提高集热性能和优化结构是集热器研究的重点。在此基础上重点介绍了真空管式太阳热水器能量收益和效率模型、标准光-热性能计算模型、自然对流的冷热水循环计算模型和强制循环太阳能热水系统计算模型。
Based on experimental tests ,numerical simulation, model analysis and other methods, this paper introduces the domestic and foreign scholars＇ research situation and development trend of all-glass vacuum tube solar collector. The key points of collector are analyzing the influence of various factors on the heat efficiency, determining the optimal tilt angle, improving the performance and optimizing the structure. On the basis of above elements, the vacuum tube solar collector energy income and efficiency model, the standard optical-thermal performance model, natural convection in hot and cold fluid circulation mode, the forced circulation solar hot water system model are introduced.
