Abstract: A rack having scalability and compatibility may be configured to reversibly adjusted to be reversibly configured to support various computerized equipment having various sizes and power supply schemes without adjusting an outer volume boundary of the rack and without replacement of the rack. The rack may include a main frame and an additional frame. The main frame may structurally support computerized equipment having a particular dimension that is a first size within an enclosure that is a first enclosure at least partially defined by the main frame. The additional frame may reversibly couple with the main frame to adjust the enclosure to be a second enclosure at least partially defined by the at least one additional frame to reversibly configure the main frame to store computerized equipment having the particular dimension that is a second size that is different from the first size.

Abstract: A cooling system and associated method may be used to perform cooling using the hydrothermal energy of supply water stored in a supply water tank that is to be complementarily supplied to a cooling tower of a freezer.

Abstract: A cooling air supplying booth apparatus for supplying cooling air to pieces of equipment in a rack unit includes a first frame and a plurality of plates. The first frame forms edges of a cuboid. The plates are fixed to the first frame and disposed at four of sides of the cuboid and form a cooling air moving path. A cooling plate includes at least one fan and is disposed at the bottom of the first frame opposite the top side of the first frame. Cooling air is supplied to the cooling air moving path through the fan, and supplied to the equipment through an outlet side in the cooling air supplying booth apparatus.
