摘　　要：节约能源和缓解高峰用电的紧张状况是制冷空调领域的专家非常关注的问题,采用蓄能系统是一种行之有效的方法。制冷潜能储存系统是以H2O/LiBr为工质的蓄能系统,通过分析其工作原理、过程、热力性并与现有其它蓄能系统进行经济性比较得知:该蓄能系统不仅能起到平衡电网峰谷负荷即移峰填谷的作用,且具有其它蓄能系统所无法比拟的优点:如蓄能密度大,当性能系数COP为4.3时,蓄能密度为400kJ/kg;可以利用各种能源如太阳能、地热能及工业废热等作为系统的驱动热源;系统简单;工作介质对环境友好,无任何污染;技术成熟;在经济性方面具有优势,投资少,在10年使用时间内的总收益是冰蓄冷空调系统的7倍。Many researchers are interested in energy storage system which is effective in saving energy and solving electricity peak-on shortage. The working principle, process, thermodynamic properties, and economic comparison of the potential energy storage system which uses H2O/LiBr as working fluid were analyzed. The results show that this system balances electricity network load, e.g. shift peak-on and peak-off. Moreover, it has other advantages such as its larger energy storage density（400kJ/kg when its coefficient of performance is 4.3）, feasibility to utilize many kinds of energy resources （solar energy, soil heat energy, industry waste heat and so on）, simple system, and working fluid friendly to our surroundings. It is an economic system that requires less investment and its gross profit is seven times larger than that of ice storage system in ten years.
