碩士 === 國立臺北科技大學 === 製造科技研究所 === 97 === 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 %.
