style="text-indent:25px">相變儲能材料的耐久性問題。這個(gè)問題主要分為三類。首先，相變材料在循環(huán)相變過程中熱物理性質(zhì)的退化。其次，相變材料從基體材料中泄露出來，表現(xiàn)為在材料表面結(jié)霜。另外，相變材料對基體材料的作用，相變材料相變過程中產(chǎn)生的應(yīng)力使得基體材料容易破壞。相變儲能材料的經(jīng)濟(jì)性問題。這也是制約其普遍應(yīng)用于建筑節(jié)能領(lǐng)域的障礙，表現(xiàn)為各種相變儲能材料及相變儲能復(fù)合材料價(jià)格較高，導(dǎo)致單位熱能的儲存費(fèi)用上升，失去了與其他儲熱方法的比較優(yōu)勢。相變儲能材料的開發(fā)已逐步進(jìn)入實(shí)用階段，主要用于控制反應(yīng)溫度、利用太陽能、儲存工業(yè)反應(yīng)中的余熱和廢熱。低溫儲能主要用于廢熱回收、太陽能儲存及供暖和空調(diào)系統(tǒng)。高溫儲能用于熱機(jī)、太陽能電站、磁流體發(fā)電及人造衛(wèi)星等方面。陜西電力儲能系統(tǒng)生產(chǎn)企業(yè)儲能在溫度變化相同的條件下，如果不考慮熱損失，那么單位體積的儲熱量水比較大，土壤其次，巖石比較小。</p><div

style="text-indent:25px">儲能是將相變材料(如石蠟)與高分子物質(zhì)(如聚乙烯)按一定比例在熱煉機(jī)上進(jìn)行加熱共混。肖敏等將石蠟與一熱塑性體苯乙烯丁二烯苯乙烯三嵌段共聚物(sBs)復(fù)合，制各了在石蠟熔融態(tài)下仍能保持形狀穩(wěn)定的復(fù)合相變材料。復(fù)合相變材料保持了純石蠟的相變特性，其相變熱焓可高達(dá)純石蠟的80％。復(fù)合相變材料的熱傳導(dǎo)性比純石蠟好，因此其放熱速率比純石蠟快，但由于sBs的引人，其對流傳熱作用削弱，所眥蓄熱速率比純石蠟慢。在復(fù)合相變材料中加入導(dǎo)熱填料膨脹石墨后，其熱傳導(dǎo)性進(jìn)一步提高，以傳導(dǎo)傳熱為主的放熱過程更快，放熱速率比純石蠟提高了1.5倍；而在以對流傳熱為主的蓄熱過程中，由于熱傳導(dǎo)的加有效應(yīng)與熱對流減弱效應(yīng)相互抵消，保持了原來純石蠟的平均蓄熱速率。</p><p style="text-indent:25px">相變儲能是熱儲能的一種利用相變材料（Phase Change Material, PCM）儲熱特性, 來儲存或者是釋放其中的熱量，從而達(dá)到一定的調(diào)節(jié)和控制該相變材料周圍環(huán)境的溫度, 從而改變能量使用的時(shí)空分布, 提高能源的使用效率。相變儲能利用的是材料在從一種物態(tài)到另外一種轉(zhuǎn)換過程中熱力學(xué)狀態(tài)（焓）的變化。比如冰在融化為水的過程中要從周圍環(huán)境吸收大量的熱量，而在重新凝固時(shí)又要放出大量的熱量。這種吸熱/放熱的過程中，材料溫度不變，即在很小的溫度變化范圍能帶來大量能量的轉(zhuǎn)換過程，是相變儲能的主要特點(diǎn)。儲能室溫下蒸氣壓低。此外，相變材料還需與建筑材料相容，可被吸收。</p><div
