摘要：本设计为北方某城市通讯机房空调系统设计。本次设计对每层都进行了冷热负荷的计算，计算结果表明新风冷负荷与日射得热之和占总冷负荷的一半以上；而冬季通过门窗围护结构传热和冷风渗透形成的热负荷占了大部分的比例。计算负荷后，将通过计算结果，来选取空调系统所需的室内机和室外机组。经过系统方案论证比较，在冷热负荷计算的基础上，最终采用了VRV空调系统。本次设计部分房间加新风系统，空调室内机均采用暗装，通过计算新风量的冷负荷和热负荷，进行新风机的选择。空调系统中的冷凝管采用硬质PVC管，风管采用离心玻璃棉，冷媒管采用去鳞无缝铜管。并且绘制了空调系统的风系统图和氟图。设计工程中不仅考虑了管道的保温与防腐的设计，而且还考虑到了减震，消声的设计。29177

Air conditioning system design for a communications room in a northern city
Abstract：The design of a city designed for northern communications room air conditioning systems. The design of each layer was heating load calculation, the results show that more than half of the new air cooling load and solar radiation and heat gain of the total cooling load; and winter Penetration through the doors and windows of the building envelope heat and cold They accounted for most of the heat load ratio. After calculating the load through calculations, the air conditioning system required to select an indoor unit and an outdoor unit. After comparison system demonstration program, on the basis of cooling and heating load calculation based on the final use of VRV air conditioning system. The design part of the room plus fresh air system, air conditioning indoor machines are concealed by calculating the cooling load and heat load of fresh air, a new fan of options. Air conditioning system condenser with hard PVC pipe, duct centrifugal glass wool, refrigerant tubes use seamless copper pipes to the scales. And draw the air conditioning system and air system diagram fluorine FIG. Design project not only considered the pipe insulation and corrosion of design, but also takes into account the damping, muffler design.
