| Summary: | 碩士 === 國立臺北科技大學 === 建築與都市設計研究所 === 105 === There’re a huge amount of building types, thus a single nature ventilation method cannot solve all interior environment issues. Since the various building types and purposes of use, as well as different environmental conditions, there’re rare studies and researches on the nature ventilation design for the traditional metal sheet factory under Taiwan’s climate conditions. Therefore, according to Taiwan’s climate environment, this study adopted Taguchi Methods and CFD (Computational Fluid Dynamics) simulation verification to carry out the experiments and intended to obtain the most ideal ventilating tower to be applied to the metal sheet factory. Since the research limitations, it only can choose three factors for the simulation experiment, and in the designed ideal in-situ environment. This study organized those aforesaid issues and data and discovered those following conclusions:
1.Influence of Designed Factor
The influence levels of factors designed in this study are B Tower Height ＞ C Blade Angle ＞A Diameter. The factor B Tower Height has the most significant influence effect on the improvement of ventilation performance for the ventilating tower.
2.Optimal Configuration
Experimental Group 6(Diameter 1.2m, height 2.7m, angle 60˚) has been determined as the most optimal design combination of this experiment according to the Larger-the-Better formula of S/N analysis method. With observing the Factor Response Graph, it found the most optimal factor combination is A2 (Diameter 1.2m), B3 (height 6m) and C1 (angle 45˚) , which is also the optimal solution of applying to the ventilating tower in the metal sheet factory of this study.
3.Ventilation Computation
Computed the ventilation of experimental groups 1-9, and verified each group’s ventilation performance verification simulation experiment, and then used the results to compute with equation and formula. It came out the Experimental Group No. 6 (Diameter 1.2m, height 2.7m, angle 60˚) has the optimal performance.
The follow-up researches can be based on the data of this study to add more design factors to conduct the experiment, as well as the comparison between the actual measurement and CFD simulation result for the product development. Mutual comparison may increase the credibility for the data report. In addition, for setting those environmental conditions of architectural physics, this study set the ideal simulation environment as that there’s no any interference by surrounding buildings, and set the climate condition as stable with no change. Therefore, this study suggested the follow-up researches shall consider adding more actual environmental measurements when setting the ventilation environment in order to respond to different climate changes and to be more closely to the applications in actual environment, so as to develop the best design of realizing the production, and achieve the goal of improving the uncomfortable interior environment for traditional factory.
