摘要

本研究於電腦資料中心資訊機房內採用不同的機櫃配置方式，以ANSYS FLUENT 套裝軟體進行氣流模擬，探討機櫃內資訊設備進風口的溫度狀況，以提供給資訊機房設計者進行規劃建設之參考。
研究中於空調條件及空間相同下，進行三種機櫃配置之氣流模擬，並改變單一機櫃發熱量及高架地板空氣洩漏量，來探討這些機櫃配置於機櫃發熱量變化時對機櫃冷卻效率之影響，以及高架地板空氣洩漏量大小對機櫃散熱之影響。
研究得知，當空調供應的風量足夠滿足機櫃需求時，資訊機房採用冷通道封閉機櫃配置時，可得到較高的機櫃冷卻效率，且當機櫃發熱量變化時，較不會影響機櫃冷卻效率，其次是採用機櫃內冷風道配置。而當資訊機房高架地板空氣洩漏量大，空調供應的風量無法滿足機櫃需求時，採用冷熱通道機櫃配置反而可以得到較好的機櫃冷卻效率。

This research is focused on performing the air flow simulation by ANSYS FLUENT for different cabinet rack arrangements in server room of the data center. The temperature distributions at air intake vent of IT equipment were predicted to provide the reference for IT data center designers.
Under the same air condition and same space, three kinds of air flow simulation of cabinet rack arrangements are performed. In these cabinet rack arrangements, we research the impact of the heat productivity changes of one single cabinet rack for the cabinet rack cooling efficiency, and the impact of air flow leakage of the raised floor for the cabinet rack heat dissipation.
From the research, when the air flow provided by air conditioners is sufficient for the cabinet rack requirement , the cold aisle sealed cabinet rack arrangement adopted by the data center is higher cooling efficiency than the others, and when the heat productivity of the cabinet rack changes, the impact is lesser on the cabinet rack cooling efficiency. Adopting the cold aisle in the cabinet rack arrangement is less cooling efficiency than the cold aisle sealed cabinet rack arrangement, but it is higher than the cold and hot aisle arrangement. However, when the air flow leakage of the raised floor of the data center is in large amount, the air flow provided by air conditioners is not sufficient for the cabinet rack requirement; in this case, adopting the cold and hot aisle arrangement is higher cabinet rack cooling efficiency than the others.
