style="text-indent:25px">總體來看，顯熱技術，相變儲熱技術和熱化學儲熱技術三種蓄熱技術形式中，顯熱儲熱的成本非常低，這主要是由于顯熱蓄熱材料，如水，砂石，甘肅相變儲熱棒生產(chǎn)廠、混凝土或熔鹽等成本較低，盛放這些儲熱介質(zhì)的罐以及相關蓄放熱設備的結構也較為簡單。但蓄熱材料的容器需要有效的熱絕緣，這對儲熱系統(tǒng)來說可能會增加不少的成本投資。相變儲熱和熱化學反應儲熱的系統(tǒng)成本要***高于顯熱儲熱，且由于相變儲熱和熱化學反應儲熱需要強化熱傳導技術與相應的設備使系統(tǒng)效率，甘肅相變儲熱棒生產(chǎn)廠、蓄能容量等性能達到一定的標準，甘肅相變儲熱棒生產(chǎn)廠，因此，除材料之外系統(tǒng)其它設備成本也相對較高。熱化學反應儲熱特別適用于太陽能熱發(fā)電中的太陽熱能儲存。甘肅相變儲熱棒生產(chǎn)廠</p><div

style="text-indent:25px">以顯熱儲熱為例，熱能儲存的量即所儲存的熱量的大小，數(shù)學上表現(xiàn)為物質(zhì)本身的比熱容和溫度變化的乘積。具體地，假設儲熱材料本身的定壓比熱容恒定且大小為Cp，且在儲熱過程中物質(zhì)載體的溫度變化為△T，則在儲熱過程中物質(zhì)載體所儲存的熱量的大小△Q可計算為△Q =Cp△T可見，給定物質(zhì)載體，其所儲存熱量的大小只與溫差有關而與溫度無關，亦即儲存熱量的大小不能反映熱量的品位，因而需要借助熱力學中的另一個重要參數(shù) 來衡量所儲存熱量的質(zhì)（即有用功）。沈陽家庭用采暖系統(tǒng)生產(chǎn)廠家能源生產(chǎn)消費使用各個環(huán)節(jié)全過程都需要用到儲能相變儲熱系統(tǒng)。</p><div
