Abstract

The invention discloses a data center cooling system and a data center cooling method. The data center cooling system comprises a data hall, a ceiling static pressure chamber, an overhead floor static pressure chamber and an equipment room, wherein a plurality of information technology cabinets with servers are arranged in the data hall; and the space from the upper ends of the information technology cabinets to the ceiling static pressure chamber is surrounded by sealing plates to form enclosures. A data center is cooled by an air treatment unit, and the air treatment problems about air recirculation, bypassing and load balance are solved by combining a data center variable air rate system. A blowing device supplies a variable air rate to the data hall (cold side) to meet the demands of the servers. The air treatment unit comprises a variable air rate air-cooling system, and cold air is supplied through fresh air refrigeration and complemented through mechanical refrigeration in warm seasons.

Description

technical field [0001] The invention relates to a data center cooling system and a cooling method thereof. Background technique [0002] For decades, data center servers have typically been cooled not by central air-conditioning units, but by means of computer room air-conditioning units (CRACs) located indoors, or close to the data center. [0003] In addition, as the density of associated computer chips increases according to Moore's Law, the data center cooling load density (W / m 2 ) has greatly increased. This has resulted in very high energy requirements for data centers, which are at least 10 times larger than typical office air conditioning applications for the same area. [0004] Recognize the need to increase data center energy efficiency and improve air management. Optimal air management requires physically separating cold and hot airflows, dynamically matching cooling system (CRAC units, or AHUs) supply airflows by changing the airflows required by servers.
