亚利桑那州尤马试验场在过去12年中成功运行了一个外部融冰盘管储存冷却系统，其标称储罐储存容量为1050吨小时（3692千瓦时）。该系统冷却506号楼，该楼由两个垂直的三层楼机翼组成，总建筑面积为86100平方英尺（7999平方米）。冰蓄冷系统是对现有冷冻水系统进行改造的附加装置，由一台220吨（774千瓦）离心式制冷机和一台80吨（281千瓦）往复式制冷机组成。该系统的设计目标是消除220的电力需求- 在1200-1600小时的峰值时段内，使用774千瓦的冷水机组。每年节省的电力设施成本净额为22450美元，在6.5年内偿还了144969美元的建筑成本。本文讨论了系统的运行和维护，以及在不断变化的放松管制环境中运行所获得的意外利益。单位:双引用:研讨会论文，佐治亚州亚特兰大，2001年

Yuma Proving Ground, Arizona, has successfully operated an external-melt ice-on-coil storage cooling system with nominal tank storage capacity of 1050 ton-h (3692 kWh) for the past 12 years. The system cools Building 506, which consists of two perpendicular, three-story wings with a total floor area of 86,100 ft2(7999 m2). The ice storage system was a retrofitted “add-on” to the existing chilled water system and consists of one 220-ton (774 KW) centrifugal chiller and one 80-ton (281 KW) reciprocating chiller. The system’s design objective was to eliminate the electrical demand of the 220-ton (774 KW) chiller during the peak window of 1200-1600 hours. Yearly net savings of $22,450 in electrical utility costs paid back the construction cost of $144,969 in 6.5 years. This paper discusses system operation and maintenance and unanticipated benefits gained from operation in a changing deregulatory environment.Units: Dual
