摘要

本文主要在探討資訊大樓(依建築物用途分類為網路機房類型) 中央空調系統的運轉模式，利用中央監控系統及能源管理系統每日記錄之運轉數據，統計並分析主機運轉時之能源效率，尋找最佳之運轉策略。
儲冰空調系統主要用來轉移電力尖峰負載至離峰時段，是一門電力負載管理的技術，不管在系統設計或控制策略上，比起傳統式中央空調系統複雜。儲冰空調系統操作也是一項專業之技術，儲冰系統相關設備之性能曲線更需要長時間記錄實際運轉數據得知，有關其運轉性能不如原始設計預期之問題，其原因大多來自於操作人員專業知識不足、不妥善利用運轉數據分析最佳操作方式、不按時進行維護保養及任意操作儲、融冰控制於不合宜之時段，這些都是造成儲、融冰效益不佳的主要原因。本研究運用空調監控系統及能源管理系連續兩年之監測紀錄，經過計算、統計、分析及比對了解資訊大樓空調主機運轉時的耗能情形，藉由分析冰水主機的四種運轉模式，統計主機耗電率及用電費用之間的關係，尋找空調系統之最佳運轉策略，以期能達到節省能源與用電費用之成效。

This study aims to investigate operational pattern of central air-conditioning system of information building which is attributed to the category of network machine room in terms of agricultural purpose, as well as calculate and analyze the optimal energy efficiency of the machine during operation and figure out the best operation strategy, by utilizing daily operational data recorded by the central monitor system and energy management system.
Ice-storage air-conditioning system serves to transfer power peak-load to off-load period. This is technique of power load management which is more complicated than traditional central air-conditioning system with regard to either system design or control strategy. Operating ice-storage system is also a professional technique. Performance curve of ice-storage system’s related equipment requires long-term data record and collection from actual operation. As for the issue that its performance is not as good as expectation of its initial design, the major reason lies in that the operators do not have sufficient professional knowledge, fail to adequately apply operational data to analyze and work out the optimal operation mode, fail to perform maintenance and repair on schedule, and arbitrarily switch between ice-storage and –melting in improper period of time. All these are major causes for poor performance of the ice-storage system. This study used air-conditioning monitor system and energy management system to monitor and record for two years, then through calculation, statistics, analysis, and contrast to figure out energy consumption by the air-conditioner of the information building, and finally through analysis on four operational modes of the air-conditioning system to calculate the relationship between power consumption rate by the machine and power cost, in order to work out the optimal operational strategy of the air-conditioning system and so achieve the goal of energy and cost saving.
