Abstract:

针对普通太阳能热水器在夜间和连续阴雨天无法正常工作的状况,提出了一种新型的建筑一体化蓄能型太阳能热泵热水器.蓄能型振荡热管太阳能集热器基于振荡热管作为热传递媒介,将瞬时太阳能或者集热器中相变材料储存的太阳能传递给热泵系统蒸发器,并利用热泵循环加热热水,用以提供生活热水.对系统进行相变材料的选择和蓄能特性的分析.以南京冬季为例,开展了建筑一体化的蓄能型太阳能热泵热水器节能特性理论计算,结果表明该热水器在节能和减少污染物排放方面都优于目前市场上的热水器.在建筑物密集化、单位居民住宅太阳能辐射占有率较低的情况下,建筑一体化的提出将节约空间,减少能源消耗和污染物排放,具有十分广阔的应用前景.
