摘要

本研究主要是針對高科技廠房系統進行模擬分析，以不改變既有設備而套用最佳化控制方式，配合數值演算法進行最佳化參數演算，應用TRNSYS動態模擬軟體，結合MATLAB、EXCEL等其他程式，進行整體系統控制，模擬該系統的耗能情形與控制情形，分析導入最佳化控制系統與原始控制系統的差異。
本研究將分析兩案例，研究結果顯示，案例一為設計一個鐘型變動的負載，進行模擬分析，模擬結果顯示，整體系統基礎變頻模型每日總消耗功率為142,232 kWh，最佳化模型每日總消耗功率為134,231 kWh，其每日總節能率約為5.0%。案例二為設計一個定負載，進行模擬分，析模擬結果顯示，整體系統基礎變頻模型每日總消耗功率為130,199 kWh，最佳化模型每日總消耗功率為128,453 kWh，其每日總節能率約為1.3%，使用最佳化參數控制的節能效益較原始控制來的佳。
在本研究中，由案例一與案例二的整體節能率來看，以冷卻水泵浦所占的節能比率最大，在兩案例中冷卻水泵浦節能率約可達10%，因此冷卻水泵浦具有較佳的節能效益。

This study focuses on simulation analysis of Semi-Conductor Factory HVAC systems without changing the existing equipments to apply optimal control methods, and with the numerical algorithm to optimize the parameters of algorithms. The TRNSYS dynamic simulation software is used in combination with MATLAB, EXCEL and other programs to operate the overall system control, to simulate the power consumption and control condition of the system, and to analyze the difference between optimal control system and the original control system.
The analysis of two cases will be provided in this study, the results of which show that Case I is designed as a bell change load to simulate analysis. The simulation results show that the overall system frequency model based on the total power consumption is 142,232 kWh, the best model for the total power consumption is 134,231 kWh, and the total saving rate is about 5.0%. Case II is designed as a given load. The results show that the overall system frequency model based on the total power consumption is 130,199 kWh, the total power consumption is the best model for the 128,453 kWh, and the saving rate is about 1.3%. The power efficiency of the optimal parameter control is better than that of the original control.
In reference to the overall saving rate of the Case I and II in this study, the cooling water pump accounts for the largest share of energy-saving rate. In the both cases, the energy-saving rate of the cooling water pump is approximately up to 10%. Hence, the cooling water pump is better in power efficiency.
