摘要

鑒於環球居住品質之急速惡化，生命共同體之加速毀滅，各國正積極展開"節能減炭"，"綠色設計"，以及各項"防治溫室效應"之永續計劃，此時此刻"自然能源"和"人力能源"，諸如太陽能、風力、地熱、海流、南北地磁，以及人力能源，皆在積極開發使用中。本研究主題乃針對"自然風力通風球"設計元件中之可變因素加以設計修正，以期改進研發出效率顯著之嶄新風力通風球 (目前通用20 型之排熱效率僅10–15%)。研究先進行客觀意願調查，第二階段則對磁推力、葉片開度、及環境排放口尺寸等三個重要設計要素分析研究，以評估風球轉速及溫度變化。結果顯示，消費者對通風球之消費意願頗高。磁推力 N to N，葉片開度33mm，環境狀排放口尺寸20×35 之設計有較佳之排熱效率，其中以磁推力為最顯著因素，降溫效率達15~20%，此研究結果對自然風力通風球之設計將有很大助益。

In viewing the universal residential quality across the world becoming worse
rapidly and the fast degradation of the natural environment, all of the world’s countries are industrially devoted to promoting the sustainable proposal of “Saving Energy & Decreasing Carbonization”, “Green Design” , “Nil-Pollution Design” and the “Anti-warming efficiency plan”. At the moment, natural energy resource and human locomotive resources such as solar energy, wind force energy, earth heat, sea tide & ocean stream, polar magnetic force and human & animal-operated locomotive forces are being initially and highly developed, and are, meanwhile, being put into use in all fields of human daily life. In this study, the researcher aimed to amend the design of the Natural Wind Forced Ball, so as to create a high efficiency NWFB in both heat-exhausting and air exchanging rates. For the time being, the “General 20” type” NWFB’s efficiency is just between 10 –15%, or below.
The first stage of the study involved investigating objectively the Questionnaire (table 5), in order to determine the correct decision for the proposal to be continued or to be abandoned. The result shows that the consumers’ favorability of NWFB tended to be high ; In the second stage of this study, an experiment, analysis and assessment was carried out on three main design factors of NWFB, such as the magnetic pushing force, the blade opening and the cylindrical discharging port, with the purpose of finding out shortcuts to increasing NWFB’s rpm, lowering NWFB’s suction temperature and improving the heat-exhausting rate and air exchanging rate for the whole room. The result shows that the magnetic force N to N, blade opening 33mm, and cylindrical discharging port 20x35mm attained better grades in both heat-exhausting and air exchanging rates. The most significant factor was the magnetic pushing force that showed gains of 15 – 20 % in lowering the temperature.
The result of this study offers great aid to the advancement of NWFB.
