摘要
水箱温度分层不仅可以提高储热水箱储存可用能的品质和能力,还能提高集热器效率,是提高整个太阳能热水系统性能的关键问题之一。目前实现水箱温度分层的主要方法有加稳流器和挡板以及改进水箱内部结构。综合国内外文献,从太阳能储热水箱温度分层的实现和维持两个方面介绍并分析了散流器、挡板以及其他因素对储热水箱温度分层的影响效果。最后展望了温度分层型储热水箱的研究趋势。
Thermal stratified storage tank is an effective method to improve the efficiency of thermal storage de- vice and it can also increase the efficiency of the solar collector. It is one of the key issues to improve the performance of the entire solar water heating system. Now the main methods of realization thermal stratification of a tank are in- stallation diffusers and baffles and improvement inner structure of the tank. The realization and maintaining of a ther- mal stratified storage tank are studied and the effects of the diffuser, baffle and other factors on thermal stratification of heat storage tank are analyzed, based on domestic and foreign literatures. At last, the tendency of the thermal strati- fied storage tank for solar energy is prospected.
