商场空调设计..doc

摘要 本次设计课题是某市商场夏季中央空调系统设计，主要任务是完成冷负荷计算；空调系统方案的经济性分析和制冷机组的选型；空调系统冷冻站的设计；楼层购物区空调机组的选型，风系统和水系统的设计；楼层办公区风机盘管系统的设计;并绘制了四层风管平面布置图、风管轴侧图、机房平面布置图，水系统轴侧图。在设计中，采用谐波反应法计算出夏季冷负荷。对于各种冷水机组的选用做了经济及技术比较分析，最后决定采用水冷离心式冷水机组。空调系统采用一次回风全空气系统。气流组织采用圆形散流器上送风，下回风，然后又利用假定流速法进行了风系统和水系统的水力计算，并对管道的保温、设备的减噪防震也做了简单设计和说明。 关键词： 空调系统 冷水机组 风系统 水系统 风机盘管 ABSTRACT This design is the Guangzhou lan west 100 markets summer the central air-conditioning system design, the primary mission completes one, two, three, four buildings load computation; Air-conditioning system plan efficient analysis and water units shaping; The air-conditioning system freezing stands design; Four buildings shopping area air conditioning units shaping, wind system and aqueous system design; Four buildings work area air blower plate tube system design; And has drawn up four winds tubes floor-plan, the wind side chart, the engine room floor-plan, the aqueous system axis side chart. In the design, uses the overtone to respond the law calculates the summer cold load. Selected regarding each kind of air conditioner has made the economical and the technology comparative analysis, finally decided used the water cooling centrifugal type cold water unit. The air-conditioning system uses time returns to the wind entire air system. The air current organization uses circular drifting on to blow of, the next time wind, then has carried on the wind system and the aqueous system computation, and to the pipeline heat preservation, the equipment reduced chirp quakeproof has also made the simple design and the explanation. Key word： air-conditioning system cold water unit wind system aqueous system air blower plate tube 目 录 1 文献综述 1 1.1 课题背景 1 1.2 商场暖通空调设计的特殊性问题 2 1.3 百货公司、商场类建筑空调系统设计的注重点 2 1.4 商场的空调设备 2 1.5 商场的空调方式 6 1.6 商场的消声隔震 6 1.7 防火、防排烟 7 2 设计基础资料 8 2.1 工程概况 8 2.2 设计依据 8 2.3 建筑基础资料 8 2.4 气象参数 9 3 空调系统冷负荷的确定 11 3.1 二（三）楼冷负荷计算 11 3.1.1 围护结构冷负荷计算 11 3.1.2 内扰(室内热源)散热形成的冷负荷 12
