Performance Analysis of a Brine-Based Ice Storage System 基于盐水的冰蓄冷系统性能分析
本文将介绍安装在伊利诺伊州自由港一家公司的盐水冰蓄冷系统。该系统始于1984年4月,服务于办公区和一小部分制造区。现在由冰蓄冷系统服务的区域以前由离心式制冷机冷却。1984年7月23日下午5:00至1984年7月24日上午11:00对该系统的运行特性进行了测试。本文将试验结果制成表格,如表1所示。 表2列出了本项目的盐水Cp和Sg。这些数据用于确定24小时内的运行特性,该特性反映了离开冰储槽(以下简称“现场”)的盐水温度升高。将讨论夜间离开现场的温度分布,以及每日排放期之前部分制冰的影响。文中还将讨论作者计算冬季冻结导致盐水体积增加的方法。 引文:研讨会,ASHRAE交易,1985年,第91卷,pt。1B芝加哥
This paper will present a brine-based ice storage system installed at a company located in Freeport, Illinois. This system, started in April of 1984, serves office areas and a small portion of the manufacturing area. Areas now served by the ice storage systems were formerly cooled by a centrifugal chiller.Tests of the operating characteristics of this system were conducted between 5:00 p.m., July 23, 1984, and 11:00 a.m., July 24, 1984. The test results are tabulated within this paper and appear as Table 1. Brine Cp and Sg for this project are listed in Table 2. These data are used to develop operating characteristics for a 24-hour period that reflects rising brine temperatures leaving the ice storage cells (hereinafter referred to as “field”). The distribution of temperatures leaving the field during nighttime hours will be discussed, as will effects of partial ice production before a daily discharge period. The method used by the author to calculate brine volume increase due to winter freezing will also be discussed.
