摘　　要：将太阳能热利用系统准稳态下的能量流动过程分为3个阶段进行用能分析,采用能量分析法和分析法对每个阶段从能量的数量和质量上进行建模,以确定系统能量及的转换、传递、利用和损失情况。第一阶段的用能分析结合了太阳辐射光谱的精确建模,并利用建立的模型对一个实际的太阳能热利用系统进行相应的计算和分析。所建立的模型可明确各种太阳能热利用系统中能量及等参数的变化过程,从而为系统的优化指明方向。A new model which divides the solar energy thermal utilization system into three phases according to the energy flow process was proposed to analyze the quantity and quality of energy of this system with the energy and exergy analysis, and combined with the solar radiation spectrum for an accurate modeling, then analyzed a solar thermal utilization system with the established model. A model which can apply to all kinds of solar thermal utilization system was established to show the change of parameters in the energy flow process, such as energy and exergy, so as to optimize the system.
