太陽能系統(tǒng)的蓄熱技術(shù)綜述

〔摘 要〕蓄熱、蓄能是發(fā)展太陽能系統(tǒng)的關(guān)鍵技術(shù)問題。針對太陽能具有的稀薄性、間歇性和不可靠性，介紹了短期蓄熱、季節(jié)性蓄熱、顯熱蓄熱、化學反應(yīng)蓄熱、相變蓄熱等幾種太陽能蓄熱技術(shù)，分析了國內(nèi)外對蓄熱技術(shù)的研究現(xiàn)狀。分析認為，相變材料的導熱率和相變蓄熱技術(shù)的應(yīng)用成本是未來相關(guān)研究的主要方向。

〔關(guān)鍵詞〕太陽能；蓄熱技術(shù)；相變蓄熱

Abstract  Heat storage and energy storage are key technical issues in the development of solar energy system. Several solar energy storage technologies， including short-term heat storage， seasonal heat storage， sensible heat storage， chemical reaction heat storage， and phase change heat storage， are introduced to address the scarcity， intermittency， and unreliability of solar energy. The paper analyzes the research status of heat storage technologies at home and abroad. Analysis shows that the thermal conductivity of phase change materials and the application cost of phase change heat storage technology are the main directions for the corresponding researches in the future.
