摘要

車輛已成為人們的生活中的主要交通工具，若能增加車輛的舒適與節能，對於人們將是一大福音。本研究以新設計出來之空氣流管理技術，運用改裝後之出、吸風口來控制車艙內的流結構，將車艙中之溫度分佈可畫分兩個獨立之溫度區塊，使駕駛者及乘客皆能依照個人需求來控制該區域之溫度，形成個人化舒適空間及減少空調系統不必要的能源消耗，以達到智慧型人性化之目的。
本研究利用計算流體力學(Computational Fluid Dynamics，簡稱CFD)的數值分析，可模擬出複雜的物理變動現象並做有系統性的分析，並利用田口實驗法將對於本系統所影響的四個重要參數(出風口風速、出風口角度、吸風口負壓、出風口與吸風之相對距離)，分析其對區域性流場形成之最佳化參數；此外建構出一座模擬實車的空調實驗平台，通過此實驗平台將模擬分析之最佳化參數應用至平台的參數設定，經由架設於人型模特兒之溫度感知器及熱顯像儀可知乘客及駕駛者的溫度變化，最後利用煙霧產生器進行流場可視化，結果顯示此平台所配置之出、吸風口及各參數的搭配，可建立出車艙內獨立的流場結構，達到智慧型車艙之區域性空調之目。

Vehicle has become a major transportation for people in our daily life. If vehicle can become more comfortable and energy efficient, it will be a good news for human being. This study utilizes new designed air flow management and refitted air outlet and inlet to control the air flow structure. By doing this, car cabin could separate into two independent temperature parts, so that the passenger could control the temperature according to one’s individual needs. Therefore, car cabin could reduce unnecessary energy consumption to achieve the technology of human intelligence.
Through the numerical analysis of Computational Fluid Dynamics (CFD), these complicated physical fluctuating phenomena can be simulated and analyzed systematically. To get the best parameter for the regional airflow form, the process utilizes Taguchi approach analyzing four prominent parameters (velocity of inlet, angle of inlet, vacuum pressure of outlet and the distance between the outlet and the inlet). In addition, by using the optimization parameters, a simulated car is built with experiment platform of air-conditioning. Through the test model with sensor of temperature and infrared thermography, this test can get the temperature of the driver in the stimulated car. Next, the simulated car devises a smoker which can visualize the airflow of the experimental platform to display the prominent parameter of the airflow. Lastly, the independent airflow structure is established, and this study of the airflow regional intelligence of the car cabin is achieved.
