摘要

本文為運用市面常見之吸頂式（DC變頻）風扇配合室內空調之組合使空間環境維持舒適度及兼顧節能之實證研究，實測原型系統PMV舒適度運算控制模組，可依據環境感測器測得之溫濕度調控風扇之轉速，在調高室內空調溫度在26℃以上之情形下，透過氣流速度之控制，達成兼顧舒適度及節能效益。本計畫運用流體力學數值計算工具CFD可分析風扇在不同轉速、溫濕度條件下，其服務範圍內各空間位置之氣流流速狀況，可提供系統之控制模組進行空間舒適度指標PMV之計算，用以評估風扇之有效服務半徑及轉速控制之使用。為了驗證系統之效益，依據一般中小企業辦公室情境建置測試環境，並調查167位不特定使用者之環境滿意度，發現即使室內溫度高達30℃亦有超過80%的空間舒適滿意度，依據ASHRAE STANDARD 55規定80%民眾可以接受的熱環境即可以稱之為熱可接受環境，即可接受的舒適度環境，經實證本系統確可有效提昇環境舒適度及達節能效益。

With this study of embedded DC ceiling fan will identify the seamless controlling to air conditioner and fans by maintaining its indoor temperature at 26 degree in centigrade. The prototype is designed by running PMV model to synchronize indoor/outdoor temperature and humidity figures impacting the best comfort to user. Using Computational fluid dynamics mythology (CFD) monitors the speed of fans in different condition of temperature and humidity that figures out the cover range radius of wind flow in correlation with speed control fan by PMV model. In order to verify the effectiveness of the system applying at most SME office environment, 167 random surveys participate our scenario test. Throughout the experiment, the results show 80% of the comfort satisfaction even indoor temperature reaching 30℃. According to ASHRAE STANDARD 55, while 80% of people agree the comfort of hot thermal environment that can be called an acceptable environment. In conclusion, we believe through the practice not only enhancing the technology features, but also creates energy efficiency with air conditioner temperature controlled and speed of DC fans providing the best interest to user and contribution to energy saving.
