摘　　要：太阳能是未来清洁能源发展的主流方向,太阳能热水器已广泛应用。普通太阳能热水器直接加热用水,用水被循环加热会形成水垢,易滋生细菌。本文提出了一种融集热、储热于一体的新型太阳能集热概念,采用理论结合实验的方法,分析了二次换热式家用太阳能热水器的热性能,用以解决普通太阳能热水器水质易结垢、易产生细菌等问题,为二次换热式太阳能热水器的广泛应用提供了有利参考。Solar energy is the mainstream direction of clean energy development in the future,and solar water heaters have been widely used.Ordinary solar water heaters directly heat water,and when the water is heated by circulation,scale will form,which is easy to breed bacteria.In this paper,a new concept of solar heat collection that integrates heat collection and heat storage is proposed,and the thermal performance of the secondary heat exchange type domestic solar water heater is analyzed by the method of theory combined with experiment,in order to solve the problem that the water quality of ordinary solar water heater is easy to form Problems such as scaling,bacteria easily,etc.,provide a favorable reference for the wide application of secondary heat exchange solar water heaters.
