介绍了加州大学长滩分校（CSULB）新建工程和计算机科学大楼非高峰冷却系统的经济合理性。中央冷却装置的设计包括为新建筑和两座相邻的现有建筑提供服务的总体规划。DOE-2.1B建筑能耗分析计算机程序用于分析替代系统，并根据详细设计布局确定施工成本。传统的暖通空调系统与冰蓄冷系统进行了比较，采用了简单的回收和寿命周期成本（LCC）技术，其中包括公用事业公司南加州爱迪生公司（Southern California Edison Company）的回扣。在两种运行模式下，将配备电动冷却器和冷却塔的传统冷冻水装置与配备浸入式盘管制冰机、螺杆压缩机和蒸发式冷凝器的冰蓄冷系统进行了比较。 分析表明，设计用于负载均衡的两台压缩机的冰蓄冷系统的LCC值最低。通过在冰蓄冷系统上投资314540美元，峰值需求减少了251千瓦，年电力成本减少了16426美元。根据公用事业公司提供的50200美元回扣，减少了高峰需求，计算成本比传统系统低25000美元，在设备的20年使用寿命内，该大学将节省221000美元。单位:I-PCITION:研讨会，ASHRAE交易，1988年，第94卷，pt。德克萨斯州达拉斯1号

The economic justification for an off-peak cooling system for a new Engineering and Computer Science Building at a California university in Long Beach (CSULB) is presented. The central cooling plant design included master plan to serve the new building plus two adjacent existing buildings. The DOE-2.1B building energy analysis computer program was used to analyze the alternate systems, and construction costs were developed from detailed design layouts. Conventional HVAC systems were compared to ice storage systems, using simple payback and life-cycle cost (LCC) techniques that included rebates from the utility, Southern California Edison Company.A conventional chilled water plant with electric chillers and cooling tower was compared to an ice storage system with submerged coil ice makers, screw compressors, and evaporative condenser under two operating modes. The analysis demonstrated that the ice storage system with two compressors designed for load leveling had the lowest LCC present worth. By investing $314,540 in the ice storage system, the on-peak demand was reduced by 251 kW and the annual electric cost by $16,426. With the $50,200 rebate available from the utility for the reduced on-peak demand, the cost was calculated to be $25,000 less than the conventional system, and over the 20-year life of the equipment, the university will save $221,000.Units: I-P
