广州电信大厦中央空调系统冷水机组运行负荷率分析

Analysis of Load Performance of the Chillers of Central Air-Conditioning System in Guangzhou Telecommunications Building

本文根据广州电信大厦中央空调系统2007年全年的运行数据,并结合办公楼空调使用的特点,分析计算了该系统的全年逐时负荷的分布情况,机组负荷率的变化规律及配置运行情况。得出了4台机组的负荷率绝大部分都集中在60%～90%之间,冷水机组的启停及运行模式基本符合大厦全年负荷的时间分布及其性能指标,说明运行调节较合理。

Based on the all - year hourly operation data of central air - conditioning system in Guangzhou Telecommunications Building in 2007 and combined the characteristics of central air- conditioning system used in office building,the all - year hourly load distribution and the variation rule of load ration of the chillers were analyzed.The results showed that the load rations of four chillers are mostly between 60%and 90%,the start - stop and operation models of chillers nearly conform to the time distribution and performance index of its all - year load,and these showed that the operation regulation was reasonable.
