Abstract

Recently, Telecom Australia has pioneered practical cost-effective methods for using the relatively high latent heat of fusion of phase-change chemicals (PCC) to provide thermal storage reserve cooling and conservation of energy in the building environment. The authors identify and outline performance characteristics of currently used PCC systems. They also introduce a novel passive building-cooling system for special high-reliability applications in remote-area communication sites. Such a low-cost minimum-maintenance system combines a thermally transparent equipment room that will maintain equipment within satisfactory environmental limits for most of the year with a special PCC thermal storage unit to give additional reserve cooling on hot days. The cool PCC storage may be provided through either a small air-conditioner or a fresh-air cycle during times of cooler weather. Mention is made of PCCs that are currently available in Australia and their suitability for application in PCC systems. PCC systems that are successfully being used by Telecom as well as exploratory PCC systems that are being investigated are briefly reviewed.<>

电信设备外壳环境可靠性的限温系统

最近，澳大利亚电信公司开创了实用的经济高效的方法，利用相变化学物质(PCC)的相对较高的融合潜热，在建筑环境中提供储热、储备冷却和节能。作者确定并概述了当前使用的PCC系统的性能特征。他们还介绍了一种新型的被动式建筑冷却系统，用于偏远地区通信站点的特殊高可靠性应用。这种低成本的最低维护系统结合了一个热透明的机房，将设备在一年中的大部分时间内保持在令人满意的环境限制内，并结合了一个特殊的PCC储热单元，在炎热的日子里提供额外的备用冷却。在天气较冷的时候，可以通过小型空调或新鲜空气循环来提供凉爽的PCC储存。提到了目前在澳大利亚可用的PCC及其在PCC系统中应用的适用性。简要回顾了电信公司成功使用的PCC系统以及正在研究的探索性PCC系统。
