本研究發展一套空調被動式冷樑結合地板出風的控制系統,利用模糊控制的技術控制現實生活上各項因素的模糊區域,並使用資料庫和模糊規則庫將資料分類和定義,根據不同的分群資料配合空調專業知識做模糊推算解模糊化後並做輸出做為控制。
本研究依照模糊理論及模糊控制系統定義出輸入和輸出變數為外氣溫濕度、室內溫溼度、冷樑裝置表面溫溼度、冰水水溫以及送風風門的開度,並依照控制範圍以及變數範圍決定模糊集合,再者以模糊集合的不同組合建立控制規則庫,當資料經過模糊規則定義後採用Mamdani推論法推論各項規則的關聯式,最後解模糊化過程採用重心法得出冷樑冰水水溫及送風風門的開度作為輸出。
由研究結果得知當外氣洩漏的結露條件與空調空間的結露條件差異越小時,對結露的控制越穩定,舒適度也落在較可以接受的範圍,當外氣條件越嚴苛,系統控制較為不穩定,同時需要使用較多的經過空調處理的低濕新鮮空氣來做調整控制。使用防結露控制系統可以達到防結露的效果,同時也可以獲得較好的冰水水溫控制來達到提高能源使用效率。
In this study, we developed the control system for a passive chilled beam system that combined with underfloor air distribution (UFAD). It can use fuzzy control technique to analyze the factors for the gray zone of real life. We classified and defined datum by using databases and fuzzy rules base. According to different grouping datum with air conditioning expertise to execute fuzzy inference. Controller outputs command to control air conditioning system after solving fuzzification.
According to fuzzy theory and fuzzy controlling system to define the input and output variables that are outdoor temperature and humidity, indoor temperature and humidity, chilled beam device surface temperature and humidity, chilled water temperature and the opening degree of supply air damper. The fuzzy sets determined in accordance with the scope of controlling and variables. Furthermore, we can establish controlling rule based on different fuzzy sets. When the passing through the fuzzy rules to define, the datum used the method of Mamdani to inference correlation. Finally, the process of solving fuzzification using gravity method to get chilled water temperature of cold beams and the opening degree of supply air damper as the output.
The result indicates when dew threshold of outdoor air leakage and dew threshold of outdoor air leakage were more approaching, the anti-dewing control and thermal comfort were more stable and acceptable, respectively. The system control unstably occurs on harsh outdoor air condition, it also needed lots fresh outdoor air to adjust the indoor condition. With anti-dewing control can provide anti-dewing effect and better chilled water control to improve energy efficiency.
