IDC机房用室外冷源降温的可行性分析
Practicability analysis of using natural cold source for cooling an IDC plant
摘要：
在分析当前电信行业空调节能技术应用背景的基础上，对廊坊电信数据中心机房空调节能改造进行了技术分析。对直接引入新风式节能系统和隔离式新风热交换系统进行了分析与比较，结果表明根据机房空调负荷和室外气象条件，应用室外新风进行机房降温在技术上是可行的。对机房空调节能改造方案的经济分析表明，室外自然冷源能有效降低通信机房空调运行能耗，可实现通信机房空调节电30%以上，投资回收期在2.5年以下，具有良好的经济和社会效益。
Abstract：
Based on the application status of air conditioning energy saving technologies in telecommunication industry, analyses the energy saving renovation of air conditioning in an IDC plant in Langfang, Hebei Province. The analysing and comparing results of directly introducing fresh air system and isolated fresh air exchanging system indicate that using outdoor fresh air for cooling the plant is practicable according to its air conditioning load characteristics and outdoor climatic conditions. Economic analysis results show that using natural cold source can reduce the operation energy consumption of air conditioning, realizing electric power reduced over 30% with recovery period less than 2.5 years, which has favorable economic and social benefits.
