R290太阳能光伏光热一体化热泵热水器系统性能研究
发布时间:2021-11-28 20:02
现如今,随着人口的快速增长和社会经济的蓬勃发展,全球范围内的能源需求也在不断快速提升。与此同时,不断提高的碳排放量也成为了当今社会的重要环境问题。目前,全球建筑能耗占能源消耗总数的五分之一左右。在2009年,我国的建筑能耗占比已经达到了23.39%,并且这一数字目前依旧在不断的变大。节能技术在我国建筑能源消耗方面有着巨大的发展潜力。随着太阳能、风能这些可持续能源的不断发展,我国的能源结构也必将变得更加合理。同时,作为有着远超电加热及燃气加热效率的热泵技术,能够满足我国部分供热需求。光伏电池的发电效率会受到其工作温度的影响。根据现有的实验结果,多晶硅电池的温度每升高1℃,光电转化效率就会下降0.4%。因此,为了提高光伏电池的效率,目前有很多降低光伏电池温度的研究,其中,PV/T集热器就是一种综合利用光伏光热能源的装置。目前有很多种类的PV/T集热器,主要可以通过工作介质来区分。常见的工作介质有空气,水,制冷剂和热管。当空气和水用作PV/T集热器的工作介质时,空气和水往往也需要承担供热的功能,所以它们会被加热到较高的温度,这就与降低光伏板温度从而提升光电转换效率的初衷产生了矛盾。本文提出了...
