PROBLEM TO BE SOLVED: To provide an air conditioner for a server system in which a surrounding air cooling type heat exchanging body and a water-cooled type heat exchanging body are applied for performing an air conditioning to reduce remarkably a running cost of the air conditioner and even if the surrounding air temperature is high, cooling in the server racks can be positively carried out.SOLUTION: This invention comprises a heat exchanging device C, a surrounding air duct 10 for feeding surrounding air to the heat exchanging device C and an exhausting duct 11 for feeding thermal exhaust gas out of a building 3. The heat exchanging device C is constituted of a surrounding air cooling type first heat exchanging body 20 having a heat pipe 37 as a heat transferring element, a water-cooled type second heat exchanging body 21, an air conditioner case 22, an air blower fan 23 and a circulation fan 24 and water feeding facility 25 and the like. Normally, surrounding air is fed by the blower fan 23 to the heat exchanging device C and the first heat exchanging body 20 performs an air conditioning within the server racks 1. In addition, when the surrounding air shows a high temperature, cooling water is fed to the second heat exchanging body 21 by the water feeding facility 25 and the air conditioning is carried out in the server racks 1 by the first heat exchanging body 20 and the second heat exchanging body 21.SELECTED DRAWING: Figure 1 【課題】外気冷却方式の熱交換体と水冷式の熱交換体で空気調和を行って、空気調和装置のランニングコストを著しく削減する。外気温が高い場合でもサーバーラック内の冷却を確実に行えるサーバーシステム用の空気調和装置を提供する。【解決手段】熱交換装置Ｃと、外気を熱交換装置Ｃへ送給する外気ダクト１０と、熱排気を建屋３の外へ送給する排気ダクト１１を備えている。熱交換装置Ｃは、ヒートパイプ３７を伝熱要素とする外気冷却式の第１熱交換体２０と、水冷式の第２熱交換体２１と、空調ケース２２と、送風ファン２３および循環ファン２４と、送水設備２５などで構成する。通常は、外気を送風ファン２３で熱交換装置Ｃへ送給して、第１熱交換体２０でサーバーラック１内の空気調和を行う。また、外気温が高いときは、冷却水を送水設備２５で第２熱交換体２１に送給して、第１熱交換体２０と第２熱交換体２１でサーバーラック１内の空気調和を行う。【選択図】図１
