電信機房環控系統之節能效益分析
Energy Saving Efficiency Analysis on Environmental Management System in Telecommunication Room
摘要
由於電信機房運作上在空調系統的電力耗能上佔有相當高的比例約20~25%，因此每年要求企業需進行汰換耗能設備及節能之改善。本論文依此需求導入電信機房空調設備更換，同時利用調升啟動壓縮機運轉的冰機回水溫度、室溫回授PLC控制風箱運轉等調控方式，並結合EMS環控系統的PLC控制，以期能提高節能效益，並藉此做實務上的差異分析與探討。在設備更換上，發現更換節能機種實際效益可達5.7 %。以PLC控制空調箱啟動數量來平衡室溫以調升冰機回水溫度，實測發現調升1℃可帶來1.9 %的節能效益，與其他研究的成效相仿。PLC控制空調箱啟停可以達到區域室溫均衡，再調升冰機回水溫度降低耗能。若運用冰機回水溫度結合EMS控制多台冰機運轉時，進行PLC 控制空調主機的啟動，則可節省 9.74% ~12.73 %的耗能。本研究結果為機房節能改善的實務探討，應用至其他機房仍需考慮設備與環境的差異；未來若能導入CFD 分析熱源與對流，預期可更有效改善熱區溫度分佈，以調升機房工作溫度，進一步降低耗能。

Companies are asked to update energy-saving cooling equipment year by year since the air conditioner systems of telecommunication rooms consume about 20~25 % of the total electricity energy. According to this requirement, this paper introduces methods including replacement of air-conditioned equipment, adjustment of the operating temperature of the water-chiller, control the operation of bellows by PLC, and control of the on-off of machines by EMS (environmental management system) to achieve the energy-saving goal. Practical testing results were analyzed and discussed. It is found that the actual benefits of replacing energy-saving equipment can reach 5.7 %. We applied balancing of room temperature by PLC control to increase the return-water temperature of ice machines and found that the energy efficiency will have 1.9 % saving benefit per 1 °C temperature increasing. It is consistent with results of other studies. As the EMS is adopted to monitor the return-water temperature of ice machines and control the on-off of the air conditioner host, it shows 9.74~12.73 % of energy can be saved. Additional parameters might be considered additionally when the above methods are applied to other environment since the above results were obtained only based on our telecommunication room. To decrease further energy consumption in telecommunication room, CFD analysis should be introduced in future to analyze the heat source distribution and the heat convection to control temperatures around the facilities.
