关于选择性吸收表面的概述目前利用太阳能的光—热轉換系統,一般說来,热效率都比較低。进一步提高热效率是太阳能利用能否普遍推广的一个重要关键。影响系統热效率的因素很多,如系統采用的吸收材料,透射材料,隔热材料,以及系統本身的結构等等。目前正在研制的各种选择性吸收表面,对于提高光—热轉换系統的效率及降低成本都具有重大的意义。什么叫选择性吸收表面?它为什么能提高热效率呢?我們知道,到达地球表面的太阳
Overview of Selective Absorption Surfaces Solar-based light-to-heat conversion systems are currently used that, in general, have relatively low thermal efficiencies. To further improve the thermal efficiency is the solar energy can be widely used to promote an important key. Factors that affect the thermal efficiency of the system are many, such as the absorption material used in the system, the transmission material, the thermal insulation material, the structure of the system itself, and the like. The various selective absorbing surfaces currently under development are of great importance for increasing the efficiency of light-to-heat conversion systems and for reducing costs. What is a selective absorption surface? Why does it improve thermal efficiency? We know that the sun that reaches the Earth’s surface
