【摘要】：近年来，信息化数字化大潮风起云涌，网络通信技术日新月异，伴随着这些信息技术的发展，数据通信机房的建设和改造工作也正如火如荼的展开。但是数据通信机房是一个耗能巨大的系统，在数据通信的建设和改造中也伴随着很多能源和安全的问题，尤其是在这个工业用电越来越发昂贵的时期，运营商都期待在安全的前提下改善机房内的气流组织。数据通信机房一般伴随着扩建、改造等一系列过程，运营商对机房的气流组织配置是否合理存在疑问。运营商希望更清晰地掌握机房的运行情况，发现并排除可能存在的隐患。为此，，需对机房的空调配置及应用情况做一个综合测评，以了解机房的温度场分布情况。本文针对这一实际的工程应用问题，对一具体的数据通信机房进行了冷负荷核算、模拟仿真、实验设计与测量和优化设计等一系列工作。本文首先核算机房的冷负荷，评估机房的冷量的充足性和气流组织方案的合理性。测量研究机房的各列头柜电压，计算出设备负荷，利用eQUEST软件核算了机房的建筑负荷，以此计算出机房的总冷负荷。然后对机房内部温度场、气流组织进行模拟。建立机房的数学模型，利用6SigmaRoom建立了机房的模型，并模拟得出机房内部的温度场和气流组织分布，得到局部过热点，模拟得出了机房的过载机柜，分析过载原因。为了验证模拟结果的正确性，对机房空调出风口的温度场、速度场进行测量，设计了测量机房内温度的实验，从机械设计、硬件设计和软件设计三个方面设计测温小车，使测温小车在房间行进测量房间内温度，验证了模拟结果的正确性，并对机房内的机架和出风口布置做了优化，对比发现优化前后数据通信机房内的温度分布，实现机房内温度场分布更加合理的目的。最后就本文的工作和不足进行了总结。
[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.
