摘　　要：通过实验方法获得平板集热器的效率随自身温度的变化规律及其能量平衡温度,并以此为依据,分析了传统太阳能集热器热循环控制方式存在的不足;提出以集热板的温升速率和太阳能辐照度来简化评估集热器集热效率的方法;给出了对太阳能集热器控制算法的优化方案和控制流程.实验数据表明:优化后集热器的集热效率随太阳辐照度的变化明显变小,太阳能的利用率得到明显提高.By use of experimental method, this article obtains the variation regulation that the flat plate collector efficiency with the change of its own temperature and the energy equilibrium tem- perature of flat plate collector. On the basis of these, this paper analyses the shortages of traditional thermal cycle control mode, puts forward the method of evaluation of collector efficiency according to the collector temperature rise rate and solar irradiance, given the optimization scheme of solar collec- tors control algorithm and draws the flow chart of the optimization control. These experimental data show that in the mode of optimization control, the smaller the collector efficiency change with solar irradiance, the more obviously the solar enerav utiliz^tinn ; A
