Heat generation in racks loaded with servers and storage devices has become much larger over recent years. At iDCs (Internet Data Centers) the problem of high local temperatures has arisen because of the mixed installation of these latest devises with legacy systems. In particular, it is difficult to maintain an even air temperature in room with a conventional under-floor air-distribution system used at iDC. Accordingly, to control such high local temperatures, we have developed a "Task/Ambient Conditioning System for Data Centers". In this system, the rack mount, task unit, and overhead task unit are developed to cool local high temperature areas in data centers. In this report, assuming that these units are open-rack types, the effects of these units on improving the temperature environment in a server room are evaluated.
