<P>PROBLEM TO BE SOLVED: To provide an air-conditioning system which saves on the space and the energy on the whole by locally treating the waste heat of high density from a communication unit and information processor room. <P>SOLUTION: A local cooling unit 21 is installed above each passage space part X between rack rows A and B, and rack rows C and D of the rack L with apparatuses 2 such as servers mounted thereon. The local cooling unit 21 is suspended from a ceiling part 25. An opening part 4 is formed in a side surface of the rack L, and a fan 1 is provided on an upper part of the rack L. The conditioned air at low temperature from the local cooling device 21 is taken into the rack L through the opening part 4 to locally treat the waste heat from the apparatuses 2. Since the local cooling unit 21 is installed in a separate and independent manner from the rack L, the static pressure is less fluctuated even when a trouble occurs in a part of the local cooling unit 21. This air-conditioning system can be easily adapted to an existing facility, and the maintainability thereof is excellent. <P>COPYRIGHT: (C)2003,JPO |
