Summary:To increase air conditioning efficiency in a data center, increase installation efficiency of a server rack, and save energy.SOLUTION: In an air conditioning control method for a data center, a server machine 3 forms a server rack row 5 by arranging a plurality of server racks 4, which are stored in multiple stages, so as to align the directions of front and back surfaces; a space between the back surfaces of the server rack row 5, which are arranged so as to face each other with a gap between them, forms a hot aisle HA; a space where the front surfaces of the server rack row 5 face each other, forms a cold aisle CA to which conditioned air from an air conditioner 2 is supplied; the conditioned air supplied to the cold aisle CA passes through the server racks 4 and flows into the hot aisle HA, to form an air circulation system returning from the hot aisle HA to the air conditioner 2. A conditioned air amount V of the air conditioner 2 is controlled based on the maximum value (face-to-face heat load difference ΔW) of the difference in heat load between the server racks 4, 4 facing each other via the hot aisle HA.SELECTED DRAWING: Figure 4 【課題】データセンターにおける空調効率を高めるとともに、サーバーラックの設置効率を高め、省エネルギー化を図る。【解決手段】サーバー機3が多段に収容されたサーバーラック4を前面及び背面の向きを合わせて複数並べてサーバーラック列5を形成し、サーバーラック列5の背面同士を間隔を空けて向かい合わせて配置した間の空間がホットアイルHAを形成し、サーバーラック列5の前面が対向する空間が空調機2からの空調空気が供給されるコールドアイルCAを形成し、コールドアイルCAに供給された空調空気が、サーバーラック4を通過してホットアイルHAに流れ込み、ホットアイルHAから空調機2に還る空気循環系統を形成するデータセンターの空調制御方法である。空調機2の空調空気量Vを、ホットアイルHAを介して向かい合うサーバーラック4、4同士の熱負荷の差の最大値(対面熱負荷差ΔW)を基に制御する。【選択図】図4
