Abstract:
PROBLEM TO BE SOLVED: To provide a simple air conditioning system capable of efficiently cooling return air by exchanging sensible heat with outside air, when the temperature of the outside air is lower than that of the return air from a server room, and of achieving energy saving effects. SOLUTION: The air conditioning system for simultaneously performing air conditioning within a server storage space 6 and air conditioning within a general room different from the space includes: a sensible heat exchanger 5; a server room air conditioning line 16 having a server room air conditioner 3 located on the downstream side of the sensible heat exchanger, taking in the air within the server storage space via the sensible heat exchanger 5 and sending the air to the inside of the server storage space via the server room air conditioner 3; a general room air conditioning line 23 having a general room air conditioner 4 and taking in the air within a general room via the general room air conditioner 4; an outside air supply line 26 for taking in the outside air via the sensible heat exchanger 5; and an air conditioning line switching means 35 capable of bypassing the return air returned from the inside of the server storage space 6 to the sensible heat exchanger 5 side to the server room air conditioner 3.

Abstract:
To cool a blade type server disposed in an air-conditioned room, the following arrangements are made. The first is at least one shell (13) having a ventilation passage disposed in the air-conditioned room (3). The second is, the following are disposed in a ventilation passage: racks (2), in which blade type servers each composed of a case with slim boards housed therein are stacked; cooling coils (10) each having a coolant passage and a cooling fin and cooling a passing air; and at least one fan unit (12) having axial-flow fans placed therein and producing air currents in one direction. The third is the fan unit forces a cooling air to flow in one direction in the ventilation passage thereby to cool the servers in the racks. The cooling coils and racks are disposed alternately so that warmed cooling air after passing through the rack is cooled by the cooling coil and then cools the next rack.

PROBLEM TO BE SOLVED: To provide an outdoor unit of an air conditioner capable of suppressing deterioration of cooling/heating capacity and a rise in power consumption even when outdoor units of air-cooling packaged air conditioners are consecutively installed and capable of minimizing the required installing space of the consecutively installed outdoor units.SOLUTION: The outdoor unit 11 of the air-cooling packaged air conditioner includes a heat exchanger 13 installed at an upper portion of a box-type casing body 12 formed in a substantially square shape in plan view, and a compressor unit (not shown) installed at a lower portion of the heat exchanger 13. The heat exchanger 13 is composed to be formed in a substantially square shape in plan view and in a tubular shape with upper and lower faces thereof opened. Further, the heat exchanger 13 is installed in the casing body 12 so that each of outer lines of corner parts of the cylindrical heat exchanger 12 is provided along a vertical line at a position corresponding to approximately one third of the length of each side of the substantially square shape of an inner-side wall face of the casing body 12. The casing body 12 includes four faces corresponding to installing faces of the heat exchanger 13 that are configured of meshes 16a.
Abstract:
PROBLEM TO BE SOLVED: To provide a cooling system which efficiently cools an electric equipment room or the like for communication-information processing, and saves energy and space and reduces a cost, by allowing coping without enlarging various air-conditioners or the like, or without increasing the installation number of the various air-conditioners or the like, even when a server is formed into a high load type and the number thereof is increased. SOLUTION: A local cooling unit 14 arranged in a space part among a plurality of servers in the electric equipment room, includes a primary cooling unit part 14a and a secondary cooling unit pat 14b connected in series each other to a refrigerator 24 for supplying a refrigerant, wherein the primary cooling unit part 14a of upstream side is arranged in a lower part of the electric equipment room, and the secondary cooling unit pat 14b of downstream side is arranged in a ceiling peripheral part of the electric equipment room, a suction port and a diffusing port are provided in the primary cooling unit part, and an upper air suction port for taking exhaust hot air in the ceiling peripheral part into the secondary cooling unit pat 14b, and an upper diffusing port for diffusing air cooled by the secondary cooling unit pat 14b toward an upper side of the space part 27 are provided.
