摘要:
综合考虑影响热损失模型的主要因素,建立了直通式太阳能真空集热管热损失及工质出口温度的数学模型,并提出了该模型的计算方法.利用美国国家可再生能源实验室(NREL)对Schott 2008 PTR70真空集热管的热性能测试结果进行验证,结果表明,热损失模拟值与实验数据值的绝对误差都小于6 W/m,相对误差基本控制在4.5%以内,故建立的数学模型可靠.同时设计了直通式太阳能真空集热管热性能的计算界面,在输入外形、物理参数和气象信息时,可以较快、较准确地输出该集热管的热损失以及工质出口温度,从而进一步完善了真空集热管的热性能模型和计算方法,为指导集热管的设计提供了便利.
Abstract:
The mathematical model of a straight-through solar evacuated tube and the corresponding calculation method considering major influencing factors are proposed. The simulation results on thermal performance of Schott 2008 PTR70 are verified by the report published by the National Renewable Energy Laboratory. The absolute errors between the simulation values of heat loss and the experimental data are almost less than 6 W/m, and most of the relative errors are less than 4.5%. Therefore, the proposed model is correct and reliable. In addition, the thermal performance calculation platform of the evacuated tube is designed and applied. By inputting shape, physical parameters and meteorological information, the heat loss and the exit fluid temperature can be obtained fast and precisely. Consequently, the mathematical model and the calculation method on the thermal performance of the evacuated tube are further improved, thus facilitating the design of such evacuated tubes.
