本文介绍了一种年蓄冰系统的设计和经济预测，该系统设计用于冷却10万平方英尺的建筑，每500平方英尺的空调地板空间或200吨的负荷为1吨。位于地下的储存区将支撑一个停车场。基本的冻土年蓄冰系统已经在伊利诺伊大学开发和测试。该系统已经开发了三年，并经过了近两年的测试。最初的概念测试是在一个4000立方英尺质量的系统上进行的，该系统旨在为中西部一个隔热良好的家庭提供夏季空调。第一年的测试表明，系统运行合理接近预测，而优化将大幅提高COP。根据这项工作，已确定45万立方英尺（含近50%水）的蓄热体将提供200吨的冷却能力，每年750满载小时或150吨- 小时。该系统预计建设成本为33万美元，可节省季节性费用51841美元，简单回收期为3.5年。该系统的成本为每吨/小时存储容量2.20美元。假设与待冷却建筑物相邻的土地可用于储存，且停车场可位于顶部；因此，土地不收取任何费用，任何计算成本也不包括停车场费用。另外还包括两种设计，一种适用于寒冷气候，如明尼苏达州的德卢斯，另一种适用于中等温暖气候，如伊利诺伊州的斯普林菲尔德。单位:I-PCITION:研讨会，ASHRAE交易，1987年，第93卷，pt。1，纽约州纽约市

This paper describes the design and economic projections for an annual storage ice system designed to cool a 100,000 square foot building with a load of 1 ton per 500 square feet of conditioned floor space or 200 ton. The storage mass, located underground, will support, a parking lot.The basic Frozen Earth Annual Storage Ice System has been developed and tested at an Illinois University. This system has been been under development for three years and has gone through nearly two years of testing. Initial concept tests were performed on a system with a 4000 cubic foot mass, designed to provide summer air conditioning for a well-insulated home in the Midwest.First year testing indicates that the system operates reasonably close to projections, while optimization will increase the COP substantially. Based upon this work, it has been determined that a thermal storage mass of 450,000 cubic feet containing nearly 50% water will provide a 200 ton cooling capacity for 750 full load hours per year or 150 ton-hours. With an estimated construction cost of $330,000, this system will provide seasonal savings of $51,841 and a simple payback of 3.5 years. The cost of this system is $2.20 per ton-hour of stored capacity. It was assumed that land adjacent to the building to be cooled would be available for the storage mass and that a parking lot could be located on top; therefore, no charge was made for the land nor do any of the calculated costs include parking lot expenses. Two additional designs are also included, one for a cold climate such as Duluth, Minnesota and one for a moderately warmer climate such as Springfield, Illinois.Units: I-P
