碩士 === 國立臺北科技大學 === 自動化科技研究所 === 93 === The modern water drinking systems are forced to develop highly thermal efficiency design resulted form the Green Energy Environment Logo, which requires lower energy consumption, saving lean water and no contamination for environment. The arrangement of internal components and the calculation of heat transfer energy balance are obviously both important and effective tools to promote the system Energy Efficiency. To overcome the hot spot in the electronic program card is also the main topic in the thesis. This thesis utilizes high heat transfer rate heat pipe to promote the performance of warm tank which exchange the energy between hot water and inlet cold water. By using the Simulink software to simulate five dynamic equations, which include mass and energy balance for hot, warm and cold tanks. The Icepak software reveals the flow field and the profile of all the internal device’s outer surface temperature, which show the local maximum temperature of hot spot. Comparing the about results and the Infrared Ray temperature, we get 2% error in hot spot. We are successful to suggest the water drink company to escape the hot spot of program card. Results express that the sixth generation of water drinking system has been up to 0.615 average steady Energy Efficiency(EEp), 0.925 hot water Dynamic Energy Efficiency(EEh) and 0.199 the ice water Dynamic Energy Efficiency(EEc). The Terminal Difference(T.D.) temperature of warm tank reduces 6℃ which represents the 3% energy saving for each inlet compensation water. The saving energy for each heat pipe is approximate 114.9kJ for each compensation water, which is low cost and design of high efficiency. All the temperature data of Icepak and results of Simulink simulation are compared with experimental data within ten percentage and the program card surface temperature controlled between 28.4℃ to 28.9℃ which shows the design can be suitable for this kind of water drinking system.
