AIR CONDITIONING COOLING AND ENERGY-SAVING SYSTEM OF DATA CENTER, AND METHOD FOR REALIZING SAME

摘要

An air conditioning cooling and energy-saving system of a data center is provided on a return air duct. The return air duct is configured to return hot air from an equipment cabinet to a precise cooling air conditioner. The air conditioning cooling and energy-saving system of the data center comprises a first cooling water heat exchange system (100), a second cooling water heat exchange system (200) and a water storage device (300). Cooling water flows out of the first cooling water heat exchange system (100), then into the second cooling water heat exchange system (200) via a first water outlet pipe (110), then into the water storage device (300) via a second water outlet pipe (111), and then into the first cooling water heat exchange system (100) via a water inlet pipe (120). Also provided is a method for using the air conditioning cooling and energy-saving system of a data center to save energy at the data center. The air conditioning cooling and energy-saving system of the data center and the method for energy saving create cooling water circulation via the siphon principle, thus greatly reducing energy consumption of an air conditioning system of a data center, and achieving energy saving and environment protection.
