摘要

本論文利用飲水機設計，考量使飲水者喝不到生水，即取熱水時不進生水的特性，又因90℃以上已可達殺菌效果，吾人設計溫控階段進水模式，同時考量兩個重要設計條件「熱水桶溫度達設定溫度97℃時系統可進生水，熱水桶溫度降至設定之93℃時即停止進水，過程中，加熱器即持續加熱，如此反覆過程，使熱水桶回覆至最佳狀態條件為停止」，並且利用軟體EES(Engineering Equation Solver)進行模擬來探討取水過程、取水方式對飲水機耗能影響，同時探討溫控補水對冰溫熱飲水機系統的影響及節能效果影響的最佳設計條件。
由實驗與理論模擬結果顯示，飲水機實際取水耗能與理論模擬耗能比較，以單取溫水方式為最省電節省1.86%，最耗能部份為取冰水部份，耗能39.7%，其次為取熱水，耗能16.38%。
經由EES模擬結果發現，當溫控啟動進水溫度設定在97℃而停止進水溫度設定在95℃，在取水過程後，使系統回覆有最大耗電情形，當溫控啟動進水溫度設計在93℃，而停止進水溫度設定在91℃，在取水過程後，使系統回覆有最大節電效果，其節電效果可達0.54 %之電量。

In the essay, I concern about the character of drinking fountain; that is, when taking hot water, the unboiled water can not enter the drinking fountain by the design. Because the water possibly has been reached the sterilizing effect above 90℃, I design the temperature control for entering water model. Besides, I concern two aspects of important design conditions. First, the unboiled water could enter the hot bucket when it reaches designed temperature 97℃.Second, water stops entering the hot bucket when the temperature lowers to 93℃. In the process, the heater continuously heats up. The heater doesn’t stop until the hot bucket reaches the best condition. Also, I apply ‘EES(Engineering Equation Solver)’’ this software to simulate the effect on drinking fountain through the process and the way of taking water. I would discuss the temperature control’s influence on drinking fountain which contains hot, warm and cold systems as well. Furthermore, I would consider the best design condition for energy conservation.
According to the research and the theory, I find out that the way of only taking warn water could save the most electricity. When taking warm water, it could save 1.86%，consumption of electricity. However, it would consume the most electricity when taking ice water. When taking ice water, it would increase 39.7% consumption of electricity. As for taking hot water, it would increase 16.38% consumption of electricity.
After the simulation of EES, I find that the system replies the condition of consuming the most electricity under two situations One is entering water temperature designed at 97℃.The other is stopping entering water temperature designed at 95℃. On the other hand, the system replies the condition of saving the most electricity under two situations as well. One is entering water temperature designed at 93℃.The other is stopping entering water temperature designed at 91℃. Therefore, the effect of saving electricity could reach to 0.54 %.
