摘要
以槽式太阳能集热器为研究对象,其中吸收器选用腔体式,通过数值模拟和正交分析的方法,对影响槽式太阳能集热器热效率的主要因素进行分析研究。研究结果表明:6种因素对热效率的影响从大到小依次为:光线沿轴向入射角度、抛物面反射率、光线沿径向入射角度、直接太阳辐照度、吸收器吸收率、抛物面与吸收器距离。
The trough solar collector which was used by the cavity type of the absorber was prepared by the numerical simulation and the orthogonality analysis method. The main factors affecting the thermal efficiency of the trough solar collector is analyzed and researched. The result shows that the six factors decreasing order which affect the thermal efficiency are the angle of incidence of light along the z axis, the reflectivity of the paraboloid, the angle of incidence of light along the x axis, the directing solar irradiance, the absorptivity of the receiver, the distance from the paraboloid to the receiver.
