　　現(xiàn)如今,隨著人口的快速增長(zhǎng)和社會(huì)經(jīng)濟(jì)的蓬勃發(fā)展,全球范圍內(nèi)的能源需求也在不斷快速提升。與此同時(shí),不斷提高的碳排放量也成為了當(dāng)今社會(huì)的重要環(huán)境問題。目前,全球建筑能耗占能源消耗總數(shù)的五分之一左右。在2009年,我國(guó)的建筑能耗占比已經(jīng)達(dá)到了23.39%,并且這一數(shù)字目前依舊在不斷的變大。節(jié)能技術(shù)在我國(guó)建筑能源消耗方面有著巨大的發(fā)展?jié)摿ΑｋS著太陽(yáng)能、風(fēng)能這些可持續(xù)能源的不斷發(fā)展,我國(guó)的能源結(jié)構(gòu)也必將變得更加合理。同時(shí),作為有著遠(yuǎn)超電加熱及燃?xì)饧訜嵝实臒岜眉夹g(shù),能夠滿足我國(guó)部分供熱需求。光伏電池的發(fā)電效率會(huì)受到其工作溫度的影響。根據(jù)現(xiàn)有的實(shí)驗(yàn)結(jié)果,多晶硅電池的溫度每升高1℃,光電轉(zhuǎn)化效率就會(huì)下降0.4%。因此,為了提高光伏電池的效率,目前有很多降低光伏電池溫度的研究,其中,PV/T集熱器就是一種綜合利用光伏光熱能源的裝置。目前有很多種類的PV/T集熱器,主要可以通過工作介質(zhì)來區(qū)分。常見的工作介質(zhì)有空氣,水,制冷劑和熱管。當(dāng)空氣和水用作PV/T集熱器的工作介質(zhì)時(shí),空氣和水往往也需要承擔(dān)供熱的功能,所以它們會(huì)被加熱到較高的溫度,這就與降低光伏板溫度從而提升光電轉(zhuǎn)換效率的初衷產(chǎn)生了矛盾。本文提出了...
