The Potimization Of Methods To Improve And Gauge Thermic Envrionment Of Communicational Engine Room

Communication room is a vital important part in the network services.Data center room usually refers to a physical space that uses informationprocessing, storage, transmission, exchange and management forcentralized processing and organic combination. The stable operation ofthe telecom equipment have higher requirement to the room environment.At the same time, the data center industry is developing faster and faster,3PH air-conditioning power consumption reached36.1kilowatt-hours everyday. It is of great urgency to develop energy saving solutions and hasvery important significance to relieve the strain on our energy anddevelop low carbon economy.In the simulation process of indoor thermal environment ofcommunication room, it involves very complicated physical process andfinds the right model to match it according to the actual demand. Basedon field test of communication room, understanding the theoreticalknowledge and application scope of computational fluid dynamics, thenumerical calculation method are studied, and the various methods arecompared, find the right model method in this article. Using k-ε model andSIMPLEC algorithm, selecting the appropriate boundary conditions andvarious parameters and using FLUENT software to simulate simplify theroom temperature field and velocity field data, it is concluded thatbecause the actual air duct in the frictional resistance and localresistance, air flow of each outlet is uneven and the highest can reach9.67m/s and the lowest is3.27m/s. Room velocity field distribution is notuniform, and the general test point distribution of air supply outlet isregular distribution, so different model using the same test method can occur large error, makes the simulation results cannot be very goodcorresponding with the customers. Through the analysis of flow field forthe back of the measuring point location optimization make matting. Thisstudy adopts orthogonal function approximation method. To a great extent,the algorithm can guarantee the spatial distribution characteristics ofdistributed parameter model and a small amount of calculation, the methodis simple. Based on the distributed parameter method based on CFDtechnology, partial differential equations to be changed into algebraicequations and the unknown parameters is obtained from the followingprocess and higher accuracy of recognition results. Result concluded fromthe simulation data is analyzed by calculation of orthogonal functionapproximation and the fuzzy cluster analysis to identify the optimal testresults of measurement point by MATLAB, finally achieved theoptimization of the measurement point position.In the current rapid development of network service, every aspect ofcommunication room needs to be optimized. The success operation of datacenter need an long-term efficient thermal environment and expect toachieve the highest availability and reliability at the lowest operatingcosts. This article presents a solution of improve the measurement pointposition to provide a preliminary thought for the test point position ofthe communication room. The thought also has certain significance for thefuture reform of the communication room.
