style="text-indent:25px">儲熱材料的研究目前主要是集中于顯熱儲熱材料和相變材料，尤以儲熱密度高、儲熱裝置結(jié)構(gòu)緊湊的高溫相變材料為主，其中各種混合鹽類因其可以在中高溫工作區(qū)域內(nèi)通過調(diào)節(jié)不同鹽類的配比來控制物質(zhì)的熔融溫度而吸引了很多研究者的興趣。除了鹽類的簡單混合，研究人員正嘗試加入金屬合金以及其它復(fù)合材料并通過納微材料合成技術(shù)和納微尺度傳熱強(qiáng)化技術(shù)制備成滿足要求的納微結(jié)構(gòu)儲熱材料，以解決其傳熱性能（導(dǎo)熱系數(shù)）、力學(xué)性能（強(qiáng)度）和化學(xué)穩(wěn)定性較差的問題。 </p><p style="text-indent:25px">有學(xué)者預(yù)測，通過增加相變儲熱物質(zhì)在復(fù)合材料中的含量和選擇相變焓更高的相變物質(zhì)，在未來數(shù)年內(nèi)，將有可能將相變儲能復(fù)合材料的儲能密度提高到150～200J/g。技術(shù)的應(yīng)用：人們對相變儲熱技術(shù)的研究雖然只有幾十年的歷史，但它的應(yīng)用十分普遍，已成為日益受到人們重視的一種新興技術(shù)。該技術(shù)主要有以下幾個(gè)方面的應(yīng)用。工業(yè)過程的余熱利用，工業(yè)過程的余熱既存在連續(xù)型余熱又存在間斷型余熱。對于連續(xù)型余熱，通常采取預(yù)熱原料或空氣等手段加以回收，而間斷型余熱因其產(chǎn)生過程的不連續(xù)性未被很好的利用，如有色金屬工業(yè)、硅酸鹽工業(yè)中的部分爐窯在生產(chǎn)過程中具有一定的周期性，造成余熱回收困難。通過在現(xiàn)有的熱流網(wǎng)絡(luò)中添加相變儲熱系統(tǒng)單元這一環(huán)節(jié)以實(shí)現(xiàn)能量的比較優(yōu)配置，提高系統(tǒng)整體的效率。</p><div

style="text-indent:25px">相變儲熱突出的優(yōu)點(diǎn)之一就是可以將生產(chǎn)過程中多余的熱量儲存起來并在需要時(shí)提供穩(wěn)定的熱源，它特別適合于間斷性的工業(yè)加熱過程或具有多臺不同時(shí)工作的加熱設(shè)備的場合，采用熱能儲存系統(tǒng)利用相變儲熱技術(shù)可節(jié)能15%~45%。根據(jù)加熱系統(tǒng)工作溫度和儲熱介質(zhì)的不同，應(yīng)用于工業(yè)加熱的相變儲熱系統(tǒng)可分為儲熱換熱器、儲熱室式儲熱系統(tǒng)和顯熱/潛熱復(fù)合儲熱系統(tǒng)三種形式。儲熱換熱器適用于間斷性工業(yè)加熱過程，是一種儲熱裝臵和換熱裝臵合二為一的相變儲熱換熱裝臵。相變儲熱系統(tǒng)功能不可替代需選擇合適的儲能技術(shù)。山西家用采暖用什么好</p><p style="text-indent:25px">相變儲熱系統(tǒng)還是太陽能熱發(fā)電和壓縮空氣/液態(tài)空氣儲能技術(shù)的關(guān)鍵。北京家庭用采暖系統(tǒng)生產(chǎn)廠家</p><p style="text-indent:25px">儲熱介質(zhì)吸收太陽輻射或其他載體的熱量蓄存于介質(zhì)內(nèi)部，環(huán)境溫度低于介質(zhì)溫度時(shí)熱量即釋放。熱量以顯熱、潛熱或兩者兼有的形式儲存。顯熱是靠儲熱介質(zhì)的溫度升高來儲存。常溫下水和卵石均為常用的儲熱材料，水的儲熱量是同樣體積石塊的3倍。潛熱儲存是利用材料由固態(tài)熔化為液態(tài)時(shí)需要大量熔解熱的特性來吸收儲存熱量。熱量釋放后介質(zhì)回到固態(tài)，相變反復(fù)循環(huán)形成貯存、釋放熱量的過程。當(dāng)然，儲熱技術(shù)的性能除了受到儲熱介質(zhì)密度等狀態(tài)量的影響外，還受到介質(zhì)本身在熱量交換和轉(zhuǎn)化等過程性能的影響。這些過程量包括介質(zhì)的換熱性能及流動性能（儲熱介質(zhì)本身也可能是換熱工質(zhì)）等，即在理論上表現(xiàn)為傳熱學(xué)和流體力學(xué)方面的特征。北京家庭用采暖系統(tǒng)生產(chǎn)廠家</p></p><br
