摘要

本研究利用熱泵系統從大氣吸取熱量來加熱水系統，建造用於可提供熱水需求的熱水加熱系統，減少和取代設置大量耗能的熱水鍋爐，並降低運轉成本且達到節能減碳的目的。
在大型熱水系統中配置熱泵系統，往往不知該如何適當的搭配設備的需求大小，幾乎都是憑著許多經驗的累積或是設計過大的儀器來運用，使得有些設備並沒有在運轉效率和成本最佳的情況下的使用，並花費了許多不必要的裝設成本以及運轉的費用。
在本文中，以Microsoft Excel的規劃求解來尋找最佳化設定，並以生命週期成本為目標函數，以熱泵配置的大小以及儲水桶大小的比例及加熱系統元件的配置大小為變數，來設計系統搭配的最佳化。
經由假設的案例結果分析得知，所發展出來的設備容量大小為最佳化模式下，有最佳解之一致性及收斂性上有良好的表現，並可成功應用於不同使用負載條件下的熱泵加熱系統設計。

In this research, we utilize heat pump system, which can absorb thermal energy from atmosphere, to heat up the water system. In addition, this system, which can cause appropriate supply of power for consumers and cut the operating cost for the purpose of energy conservation and carbon reduction, is designed to substitute for the traditional energy-consuming hot-water boiler.
Equipping with heat pump system in large-scale thermal water system, we frequently wonder how to design for fitting the size of the main instrument. Even with the accumulation of experience or oversized fabrication designs, many systems are doomed to optimize poorly between operating and cost efficiencies; that is, those charge us more for unnecessary assembly and operating expenses.
In this thesis statement, we derived the best solution to the optimization from the Microsoft Excel program by regarding life-cycle costing as objective function, viewing sizes of heat pump system, water tanks and devices for heating system as variable functions respectively.
Analyzing simulation results of assumptions, we acquired that the heat pump system design of the optimized model, with unity and convergence of the best solution, can work as well under different loading conditions.
