由於近年來特殊空調產業發展之應用提昇,產業中皆已廣泛應用潔淨室,由高外氣引入及多次過濾以維持潔淨環境條件,而需付出極高耗能。而數據中心因電子設備之集中管理所產生高顯熱負荷,使得數據中心空調系統面對嚴苛之高顯熱空調負載,相同需付出極高耗能成本,因此本文首先探討潔淨室的空調系統可作減少風扇濾網機組(FFU)之覆蓋率,應用計算流體力學(CFD)模擬FFU關閉方式及關閉率,最後再以實際量測分析來檢視關閉FFU之節能可行性。結果發現在潔淨等級ISO 5(Class 100)之潔淨室,在關閉率達到10%,仍可維持無塵室中之環境要求等級,可達到省能之要求。此外,亦針對數據中心不同供風配置設計做分析探討,進行模擬分析比較各種氣流分配系統對熱量的去除率,進而規劃與設計適當的供風配置系統,結果使用高架地板配置穿孔板由地板供風搭配回風口回風,並採用有效冷熱風道分離概念之空調設計,可提供較佳之氣流分佈及較滿意之散熱效果,也應用機櫃冷卻指標(RCI)評估數據中心運轉設計之性能。藉由本研究CFD之模擬分析與現場量測驗證,期能針對潔淨室及數據中心等特殊空調系統在能源節約與性能改善方面提供重要之參考。
Modern manufacturing industries air increasingly turning to critical HVAC technology for the development of new products and compliance with environment requirement. Cleanroom and data center cooling system, critical to a wide range of high-tech industries and IT technology, are extremely energy intensive. However, little knowledge or quantitative information about energy efficient HVAC system has been conducted. With cost of energy rising, value of conservation grows. Since HVAC systems of cleanroom and data center operate continuously, it is essential and significant to consider energy efficient strategies and designs to maximize efficiency in the operation of the facility. In this study, the energy saving strategy for HVAC system performance by reduction of fan-filter-unit(FFU) coverage in a cleanroom will be investigated. The understanding of the key parameters contributing to energy performance can be developed by case studying a ISO Class 5(Class 100) cleanroom through not only by field testing but also by CFD aided contamination control simulation. The results reveal that cleanliness level can be maintained satisfactorily at the 10% reduction of FFU coverage rate. Besides, numerical simulation by using CFD codes were conducted to investigate the influence of alternative layouts for air distribution in a newly constructed data center. Through the simulation of different airflow distribution patterns, the optimum practice for cooling airflow arrangement can be identified easily. The simulation results also revealed that the case with a vertical under floor cooling architecture can provide satisfactory airflow distribution and thermal management. Rack cooling index (RCI) has been used to evaluate the cooling performance of environmental conditions for the datacom facility. The study through CFD simulation and field measurement not only can identify the best practice for airflow distribution, but also can provide the energy-efficient and cost-effective HVAC system specific for cleanroom and datacenter facility.
