摘要
对典型的太阳能热水系统建立了数学模型。结合工程实例和长沙地区太阳能辐射特征,运用该模型分析了在给定单个家庭典型用水模式下集热器面积和贮热水箱体积对太阳能热水系统热利用性能的影响。优化集热器面积和贮热水箱体积,在减少投资的同时,提高太阳能热水系统的综合性能。集热器面积和水箱体积的优化匹配设计有利于提高系统的能量转换效率。
A mathematical model was developed for typical solar water heating system.The practical engineering examples and characteristics of solar radiation in Changsha are expounded with the model.The effects of collector area and storage volume of hot water tank on the solar water heating system＇s thermal performance are analyzed for a certain family with typical water consumption pattern.Collector area and storage volume of hot water tank shall be optimized,while reducing investment and improving the overall performance of solar hot water system.The optimal matching design of collector area and tank volume is conducive to promote energy conversion efficiency.
