儲冰式空調系統藉著夜間儲冷、日間釋冷的特性，將電力消耗轉移至離峰時段，以削減日間尖峰負載的特性，在能源日漸不足的今日更形重要。但由於不良的設計，未考慮主機、儲冰槽及其它附件等操作特性，以致無法有效地提供所需要的冷能並進行電力的節約。有鑑於此，本文發展儲冰式空調系統之最佳化分析方法，以最小生命週期成本為目標建立冷凍系統及供風系統之最佳操作。
在考慮大氣環境溫度、空調負荷大小及與儲冰槽之匹配關係，建立主機及附屬設備之耗電模式，並進行儲冰槽儲冷及釋冷的分析，藉著既有的內融冰式儲冰槽產品，建立熱傳上之分析方法，而得出其熱傳係數與含冰量之關係式。然後將儲冰空調系統的操作建立其最佳化數學模式，以初始成本及能源運轉成本作為目標函數，以主機及儲冰槽的性能作為限制條件，以動態規劃方法求解所建立的最佳化模組，並進行主機優先、儲冰優先之生命週期成本及回收年限的分析比較。
最後並將最佳化分析擴展至供風系統部份，利用儲冰式空調系統之低溫供冷特性，以動態規劃方法進行低溫供風方式下的風管尺寸及風扇全壓分析，建立最小生命週期成本的最佳化設計，同時並結合冷凍系統部份進行經濟效益評估，以使儲冰式空調系統之運轉更為節約。
