<P>PROBLEM TO BE SOLVED: To provide a rack with an air-conditioning duct and a rack cooling system that can efficiently cool the inside of a rack of a collective and mixing loading type without receiving the influence of an indoor environment, and generate only a small loss of energy. <P>SOLUTION: A suction duct 15 is provided inside a door 13. An air suction fan 16 is fitted on the bottom of the suction duct 15 to forcibly suck cold air from the outside. A plurality of inlets 17 continuing vertically are provided on the side surface of the shelf board 14 side of the suction duct 15. An exhaust fan 20 is provided on the upper part of the rack 10 to forcibly exhaust warm air inside the rack 10. The opening section area of the suction duct 15 is sequentially changed depending on a distance apart from the air suction fan 16, and the cold air sucked by the air suction fan 16 is almost equally exhausted into each step of the shelf board 14. <P>COPYRIGHT: (C)2004,JPO |
