Research on optimization of air flow organization in substation room air conditioning based on CFD

Abstract

Due to the continuous improvement of the computer network communication level and the acceleration of data transmission speed, the hardware configuration of the digital signal processing room on the second floor of this unit has become more intensive, and the power consumption and heat generation have also increased.Although the constant temperature and humidity precision air conditioning system has sufficient theoretical cooling capacity, it uses the conventional diffusion air supply mode of cooling the surroundings first and then cooling the device.In a computer system, there are many local over temperature faults due to the uneven distribution of computer load in many areas, which is very difficult to deal with.The existing air distribution cycle has been unable to meet the cooling requirements of equipment with high energy consumption.The examples of the application of optimization and transformation of airflow organization based on CFD in State Grid’s substation computer room was introduced, it has a certain reference significance for energy saving and consumption reduction in computer rooms design.
