Thermal Energy Storage with Encapsulated Ice
封装冰的热能储存
不断增长的热能存储冷却系统市场推动了许多创新,本文介绍了一种封装式冰系统,其存储密度达到1.6 ft3/吨小时(288 x 103 kJ/m3)。还介绍了一种近距离蒸发器,该蒸发器使用液体喷射器作为制冷剂供给,制冷系统使用液体过量供给,并可在低冷凝条件下运行以获得最大效率。使用传热分析计算储罐充放电期间的预测传热率。用于分析的参数用于预测计划于1987年秋季完工的装置的运行情况。
该水箱可以在16小时内充满电,并在6小时内排放,根据分析,这些充放电率使该方法适用于建筑冷却应用。单位:双引文:研讨会,ASHRAE交易,1988年,第94卷,pt。德克萨斯州达拉斯1号
The growing market for thermal energy storage cooling systems has prompted numerous innovations, This paper describes an encapsulated ice system that achieves a storage density of 1.6 ft3/ton-hour (288 x 103 kJ/m3). Also described is a close-approach evaporator that uses a liquid jet for refrigerant feed, The refrigeration system uses liquid overfeed and can operate at low condensing conditions for maximum efficiency. Predicted heat transfer rates during tank charging and discharge are calculated using heat transfer analysis. Parameters for the analysis were used to predict operation of an installation scheduled to be completed during the fall of 1987. The tank can be fully charged jn 16 hours and discharged over 6 hours, according to the analysis, These charge and discharge rates make this approach suitable for building cooling applications.Units: Dual
