利用模擬退火法與和弦搜尋法比較中央空調之最佳負載分配

The Optimal Loading Distribution of Air-Condition System by Simulated Annealing and Harmony Search Algorithm

指導教授 : 鄭鴻斌

摘要


空調「最佳化」必須將所有能調控的元件列入考量,如冰水主機、冰水泵、冷卻水泵及冷卻水塔。若能找出低耗能的各設備搭配,且滿足所需製冷量,即為空調最佳負載分配。因此,本研究利用模擬退火法(Simulated Annealing, SA)及和弦搜尋法(Harmony Search, HS)找出最佳化中央空調之負載與傳統平均負載法(Equal Loading Distribution, ELD)做比較,並且發展出便於人性操控與計算的決策支援系統(Decision Support System, DSS),透過本研究可找出不同室內負荷量時較佳的節能效果,結果顯示HS的計算結果普遍的比SA還快速且擁有較高的節能表現,對於本研究所使用之中央空調冰水系統HS可最高達至11.9%的節能效益,達成提升整體設備效益的目的。

In order to reach the optimal air-conditioning, it is necessary to consider all controllable equipmentsuch as chiller plant, chiller pumps, cooling water pumps and cooling towers.If all equipment collocations of low energy consumption are founded and demand ofrefrigerationcapacity is satisfied, the optimal load distribution of air conditioning can be reached.Therefore, this study used Simulated Annealing(SA) and Harmony Search(HS) to find the optimal load distribution and compared with the traditional Equal Loading Distribution method (ELD) to develop the Decision Support System (DSS) which is easy to manipulate and calculate for humanity.Through this study, the better effects of energy conservation in different indoor load capacity can be founded. The result shows that HS is rapider and has better energy conservation than SA. For central air-conditioning system applied in this study, HS can even reach up to 11.9% of energy conservation to reach the purpose of improving overall equipment effectiveness.
