摘要

近年來，科技進步神速，加上全球經濟的發展，人類不斷增加電器及通訊類商品，導致對消耗性能源產品需求量有增無減，工業設備因應生產需求也不斷擴廠，而工廠為求節省成本多半使用鐵皮屋建造，在電力供應吃緊下，如何提供能源又不破壞環境及消耗其它燃料是目前各學者企業研發重要目標之一。由於台灣處於亞熱帶，夏季長久炎熱，在陽光直射下，廠房悶熱造成工作效率不彰，於是廉價的空氣對流器逐漸被工廠採用，且一個工廠安裝數量都是數個或數十個以上，為求電力節省與配合政府環保節能政策，本文利用空氣對流器提供一種乾淨、安全、持久的綠色能源，設計應用空氣對流器驅動小型發電機之照明系統研製。本系統藉由工廠內外溫差及氣壓差，熱氣上升氣流自葉片縫隙外排，及工廠外風力或雨滴形成壓力驅動，驅使小型發電機旋轉，輸出電壓整流後經過DC-DC功率轉換電路，將電能儲存至蓄電池再供給至照明設備，為了提高發電機效率及系統可靠度，必需考量各機械結構材質與設計，並減低各結構間磨損量，以最簡之元件組成，避免系統過於複雜，造成日後維護的困擾。本研究所發展之空氣對流器驅動發電機系統屬於創新性研發技術，目前國內外尚無相關文獻討論，故本系統為首創之研究。藉由產學合作投注於應用與研究，更能加速本系統之穩定性及商品化，並可延伸於其它產業，提供多樣性之替代能源。

Modern technologies and global economy have been developed rapidly. To cope with the expanding market, the industry enlarges the scale of the production line. To lower the investment cost, many industry factories usually are constructed with paint-coated steel panels without seriously taking the conservation of energy into account. In the limited power supply, how to offer the energy and not to destroy the environment or consume other fuel has become an important research topic. The weather in Taiwan is humid and hot in summer. Long exposure to the sunlight and high room temperature make ventilation a necessity in the factory building. Therefore, the air ventilators can improve it. For the government's environmental protection policy, our research can provide a clean, safe and green energy generation system.
The system research and development herein is a micro charge/discharge system
by a generator which is driven by the air ventilator. The system extracts the energy from air convection caused by the pressure and temperature difference between the inside and outside of the factory building. Moreover, the blowing wind and the rain drop outside the building can provide driving forces for the system. The pressure difference in the ventilation duct via the fan drives the rotation of the generator. The output of the generator is rectified and then stored in the super-capacitors. After the fabrication and testing of the prototype, this system has been proved feasible for practical application.
