Cold wall cooling device for data center

Abstract

The invention discloses a cold wall cooling device for a data center. The cold wall cooling device for the data center is mainly characterized in that a floor comprises anti-static floor blocks and ventilative floor blocks; a cabinet is arranged on the anti-static floor blocks; the ventilative floor blocks are arranged on the portions, corresponding to a cold air duct and a hot air duct, of a support correspondingly; fans are arranged below the ventilative floor blocks corresponding to the cold air duct; an outer frame of the cold air duct is connected with horizontal beams of the support through connecting pieces; surface air coolers are arranged under the floor, and each surface air cooler is connected with a water supply main pipe and a water return main pipe through a water supply branch pipe and a water return branch pipe; the water supply main pipe and the water return main pipe are connected with a refrigerating unit; the side, namely the air return side, facing the hot air duct of each surface air cooler is provided with a draught fan. According to the cold wall cooling device for the data center, tail-end air-conditioning refrigeration equipment does not occupy the building area of a data center computer room, the cabinet covering rate (CCR) is increased, and thus more server cabinets can be arranged in the same building area so as to increase the profits and incomes of the owner; meanwhile, the problems that air distribution in the computer room is not even, and the temperature of local parts of the cabinets is high are solved, and a good energy saving effect is achieved.

Description

technical field [0001] The invention relates to a matching air conditioner, in particular to an air conditioner used for refrigeration in a data center. Background technique [0002] With the continuous development of the Internet, the construction speed of data centers is astonishing, and the resulting huge power consumption has become an unavoidable problem in the development of data centers, which needs to be solved urgently. As a data center, the main energy consumption includes four parts: IT equipment energy consumption, UPS conversion energy consumption, refrigeration equipment energy consumption, lighting and fresh air system energy consumption. Among them, the energy consumption of refrigeration equipment accounts for 30% of the total energy consumption of the data center. [0003] The root cause of the high energy consumption and low efficiency of the refrigeration system lies in the traditional design concept and the unreasonable air flow organization in the mach...
