Data center air-conditioning system

Abstract

The invention discloses a data center air-conditioning system. The data center air-conditioning system comprises a heating pipe system, a mechanical refrigerating system and a backup system. The datacenter air-conditioning system has three operation modes which include the heating pipe mode, the mechanical refrigerating mode and the mechanical refrigerating and heating pipe simultaneous operationmode. The best operation mode is selected according to the different outdoor temperature conditions, and efficient energy-saving operation of the air-conditioning system is guaranteed. A cold accumulation tank is additionally disposed in the air-conditioning system, and cold accumulation is performed on the cold accumulation tank when the air-conditioning system works normally; when the mains supply breaks down, the refrigerating capacity of the cold accumulation tank is provided for a data center, so that safe operation of the system is guaranteed; and meanwhile the air-conditioning system adopts the modularized separated systems, so that the system safety is further improved.

Description

technical field [0001] The invention belongs to the technical field of data center refrigeration, and in particular relates to a data center air-conditioning system. Background technique [0002] With the rapid development of applications such as the Internet, mobile Internet, cloud computing, and big data, the pace of global data center construction is accelerating. At the same time, the problem of energy saving and consumption reduction in data centers has become more prominent. According to statistics, data center air-conditioning accounts for about 40% of the entire data center's energy consumption. The more air conditioners are used, the more power they consume, which directly leads to the crisis of power cuts in summer and the problem of a large amount of energy consumption. [0003] In view of the all-weather operation of computer room air conditioners, when the outdoor wet bulb temperature is low, especially in the north or in winter, making full use of natural col...

[0004] In addition, the cooling capacity in the data center is increasing. Once the power supply fails, although the server can continue to run on the UPS system, the temperature of the computer room will rise rapidly due to the shutdown of the cooling equipment, which will still cause the server to overheat and stop running.
