Data center indirect evaporative cooling system and controlling method

Abstract

The invention discloses a data center indirect evaporative cooling system and a controlling method. The data center indirect evaporative cooling system comprises an outdoor water system and an indoorcompressor system; and an outdoor water refrigeration assembly comprises a heat exchange core body, a water tank and a circulating water pump, wherein the water tank is arranged below the heat exchange core body, a spraying pipe is arranged at the top of the heat exchange core body, a water outlet in the water tank is circularly connected with the spraying pipe through the circulating water pump and a pipeline, and the water tank is further provided with a water inlet pipe and other components. According to the system and the method, the optimal controlling problem of an existing data center indirect evaporative cooling system is solved, and the effects of comprehensive energy-saving controlling and effective data center PUE value reduction are achieved.

Description

technical field [0001] The invention belongs to the technical field of data center computer room air conditioning control, and in particular relates to a control method and device for an indirect evaporative cooling system of a data center. Background technique [0002] According to the energy consumption survey and analysis of the data center computer room, the power consumption generated by refrigeration and air conditioning accounts for about 37% of the total power consumption required by the data center computer room, and the energy consumption of refrigeration and air conditioning has become a key factor affecting the PUE value of the data center . In order to reduce the PUE value of the data center, through the transformation of the traditional computer room air conditioner using compressor cooling, the solution of using natural cold sources to cool the computer room has become a hot pursuit of data center cooling. The indirect evaporation source system is currently a...
