摘要
隨著現代人生活品質提升，對車內環境之舒適度的需求日漸受到重視。對於曝曬於烈日下之汽車車廂內所產生的種種高溫問題，近年來已成爲工程師所要面臨並解決的一大難題。過去有研究提出太陽能自動換氣降溫系統，利用太陽能板將太陽能轉換成電能用以驅動車內之鼓風機，此系統可將室外較低溫之空氣引入車內，使車內、外空氣循環對流，藉此達到降溫之效果。 本研究特別針對鼓風機之啓動時間進行改善，當車主離開汽車後不立即啓動，而是當車內達到設定時間或設定溫度時再啓動系統，不僅可以將額外的太陽能儲存至車上的電瓶以供使用，又可達到相同之降溫效果。本研究並使用STAR-CD數值分析軟體模擬出啓動溫降系統後車內之溫度場與速度場之變化，結果顯示本系統不僅節省了許多額外的能源負荷，並有效的將車廂內環境降至較舒適之溫度。

With the improvement of life quality for modern people, the comfort requirement of driving environment has gradually attracted more attention. Various problems of high temperature resulted from the vehicle carriage exposed to the scorching sun have become one of the difficulties that engineers encounter in recent years and need to find solutions. In the past, the solar-driven ventilation and temperature cooling system was proposed, which utilized solar cells to transform solar energy into power in order to drive the blower inside the vehicle; this system could suck the outside air at lower temperature into the vehicle, improving the air circulation in order to lower the temperature. This research particularly aimed to improve the start-up time of the blower. The system will be activated when reaching the set temperature or time instead of starting up immediately after the driver leaves the vehicle. This not only can store the extra solar energy in batteries of the vehicle, but also be able to achieve the same cooling effect. This research also utilized STAR-CD analytic software to simulate the variation of temperature field and velocity field inside the vehicle after activating the cooling system. The result displayed that this system can extra save a lot of energy as well as to effectively lower down the temperature inside the vehicle to a more comfortable level.
