Embodiment 1

[0051] A method for establishing and analyzing a flow field model in a communication room, comprising:

[0052] (1) if figure 2 As shown, a 40m×15m×3m communication machine room 3D model is established by Gambit software. The machine room has 6 surfaces, including 5 rows of communication racks, and 10 air-conditioning outlets that independently control temperature and wind speed;

[0053] (2) if image 3 As shown, the three-dimensional model of the communication room is mainly divided by the tetrahedron (triangular pyramid) grid type. The grid size on the surface of the communication rack changes from dense to sparse, and an unstructured grid is obtained. Considering the full utilization of computer memory resources And operating efficiency issues, the number of grids can be appropriately reduced when the quality of grid division is high. Preferably, the grid spacing is finally set to 500mm, and a total of 92943 grid units are divided. The grid quality is in accordance with ...

Abstract

The invention discloses a method and system for establishing and analyzing a flow field model of a communication room. The method comprises following steps: establishing a three-dimensional model of a communication room; dividing the three-dimensional model of the communication room by the tetrahedral grid type to obtain an unstructured grid; setting the boundary types of a wall surface of the communication room and a frame surface of the communication room as the wall surface, and a boundary type of an air-conditioning supply outlet of the communication room as a speed inlet; based on the unstructured grid and by selecting the K-[epsilon] turbulence model, starting calculation from the speed inlet to obtain a temperature field and a speed field of the communication room after N times of iteration; establishing a flow field model of the communication room by means of the temperature field and the speed field of the communication room; analyzing multiple conditions of the communication room by means of the flow field model of the communication room and making an energy saving scheme of the communication room. The invention can reduce the running cost of the communication room, comprehensively analyze the flow field environment of the communication room, formulate an energy saving scheme of the computer room and improve the accuracy of the energy saving control.

Description

technical field [0001] The invention belongs to the field of computer simulation, and more specifically relates to a method and system for establishing and analyzing a flow field model in a communication room. Background technique [0002] With the rapid development of the communication industry, the energy saving of the communication equipment room has attracted widespread attention. The equipment in the communication room needs to operate normally and permanently under a certain temperature environment. At present, the temperature of the machine room is mainly regulated by the air conditioner, which runs continuously at a constant temperature and speed all year round, resulting in a large amount of energy consumption. For energy-saving monitoring of communication equipment rooms, temperature is an important indicator, and the temperature value is time-varying and coupled. [0003] At present, the establishment and analysis of the flow field model in the communication equi...
