【摘要】：近年來，信息化數(shù)字化大潮風起云涌，網(wǎng)絡通信技術日新月異，伴隨著這些信息技術的發(fā)展，數(shù)據(jù)通信機房的建設和改造工作也正如火如荼的展開。但是數(shù)據(jù)通信機房是一個耗能巨大的系統(tǒng)，在數(shù)據(jù)通信的建設和改造中也伴隨著很多能源和安全的問題，尤其是在這個工業(yè)用電越來越發(fā)昂貴的時期，運營商都期待在安全的前提下改善機房內(nèi)的氣流組織。 數(shù)據(jù)通信機房一般伴隨著擴建、改造等一系列過程，運營商對機房的氣流組織配置是否合理存在疑問。運營商希望更清晰地掌握機房的運行情況，發(fā)現(xiàn)并排除可能存在的隱患。為此，，需對機房的空調配置及應用情況做一個綜合測評，以了解機房的溫度場分布情況。本文針對這一實際的工程應用問題，對一具體的數(shù)據(jù)通信機房進行了冷負荷核算、模擬仿真、實驗設計與測量和優(yōu)化設計等一系列工作。 本文首先核算機房的冷負荷，評估機房的冷量的充足性和氣流組織方案的合理性。測量研究機房的各列頭柜電壓，計算出設備負荷，利用eQUEST軟件核算了機房的建筑負荷，以此計算出機房的總冷負荷。 然后對機房內(nèi)部溫度場、氣流組織進行模擬。建立機房的數(shù)學模型，利用6SigmaRoom建立了機房的模型，并模擬得出機房內(nèi)部的溫度場和氣流組織分布，得到局部過熱點，模擬得出了機房的過載機柜，分析過載原因。 為了驗證模擬結果的正確性，對機房空調出風口的溫度場、速度場進行測量，設計了測量機房內(nèi)溫度的實驗，從機械設計、硬件設計和軟件設計三個方面設計測溫小車，使測溫小車在房間行進測量房間內(nèi)溫度，驗證了模擬結果的正確性，并對機房內(nèi)的機架和出風口布置做了優(yōu)化，對比發(fā)現(xiàn)優(yōu)化前后數(shù)據(jù)通信機房內(nèi)的溫度分布，實現(xiàn)機房內(nèi)溫度場分布更加合理的目的。 最后就本文的工作和不足進行了總結。
[Abstract]:In recent years, with the rapid development of these information technologies, the tide of information digitization is surging and the network communication technology is changing with each passing day. The construction and transformation of the data communication computer room is also in full swing. However, the data communication room is a system that consumes a great deal of energy, which is accompanied by a lot of energy and security problems in the construction and transformation of the data communication. Especially at a time when industrial electricity is becoming more expensive, operators are looking to improve airflow in computer rooms on a safe basis. The data communication computer room is usually accompanied by a series of processes such as expansion and transformation. Operators have doubts about whether the airflow distribution in the computer room is reasonable. The operators want to have a clearer understanding of the operation of the computer room. For this reason, it is necessary to make a comprehensive evaluation on the configuration and application of air conditioning in the computer room in order to understand the distribution of the temperature field in the computer room. A series of work such as cooling load calculation, simulation, experimental design, measurement and optimization design are carried out in a data communication computer room. This paper first calculates the cooling load of the computer room, evaluates the adequacy of the cooling quantity and the rationality of the airflow organization scheme, measures the voltage of each row head cabinet in the research room, calculates the equipment load, and calculates the building load of the computer room by using eQUEST software. The total cooling load of the machine room is calculated by this method. Then the temperature field and airflow distribution inside the computer room are simulated. The mathematical model of the engine room is established, and the model of the engine room is established by using the 6 Sigma Room. The temperature field and the distribution of the airflow in the room are simulated, and the local over-hot spot is obtained. The overload cabinet of the computer room is simulated and the cause of overload is analyzed. In order to verify the correctness of the simulation results, the temperature field and velocity field of the air-conditioner outlet in the engine room were measured, and the experiment of measuring the temperature in the machine room was designed. The temperature measuring vehicle was designed from three aspects: mechanical design, hardware design and software design. The temperature measurement vehicle is used to measure the temperature in the room, which verifies the correctness of the simulation results, and optimizes the arrangement of the rack and the air outlet in the computer room. The comparison shows that the temperature distribution in the data communication room before and after the optimization is found. The temperature field distribution in the computer room is more reasonable. Finally, the work and shortcomings of this paper are summarized.
