高层综合楼建筑设计CAD图纸+说明书 摘要 设计总说明
该建筑位于上海市,本工程为高层综合楼1-6层中央空调设计,综合楼
高约72米,是一座综合性建筑物,总建筑面积为6696㎡,其中空调面积为3206㎡。综合主楼地面18层,本楼以办公室和会议室组成。本设计中室内设计要求参照舒适性空调室内计算参数,初步设计为:夏季:干球温度为26度,相对湿度为55%,风速≤0.3m/s。
根据所给出的建筑条件图进行房间编号,确定各房间的负荷种类,房间尺寸,门窗尺寸,围护结构的传热系数,房间的朝向、传热面积、室外气象条件、室内设计参数。用excel表格将各房间的逐时负荷统计计算出来,确定最大负荷出现的时间以及最大负荷数值。根据节能设计标准要求,结合计算软件,采用冷系数法对整个综合楼的冷负荷进行逐时计算。经计算得出,该酒店的总冷负荷为458.485KW,最大负荷时刻出现在晚上16:00。
由计算出的总负荷,来确定系统形式,此次的设计中,我将一层分为水系统一区;2-6层为水系统二区,采用风机盘管加新风的方式。结合建筑物的特点,在冷冻水系统确定中我选择闭式、异程、双管制、单级泵,变流量系统,这种空调水系统具有结构简单,初期投资小,管路不易产生污垢和腐蚀,水泵耗电较小等优点。设计中将空调机房设置在地下层,采用水冷式处理,选用水冷螺杆式空调机组,型号为cuw80e5y。
根据给定的设计参数和计算出的参数,查找相应的资料手册,进行系统的水力计算,在水力计算中,根据已绘出的系统草图,确定系统的最不利管段,标注最不利管段的节点,采用假定流速法进行分段的水力计算,得出整个管路的管径和整个管路的水力损失,对于管路水力损失较大的管段进行管径调整,得出合理的沿程总水力损失。根据计算的沿程水力损失,合理估算局部水头损失所占的份额,确定总水力损失,根据各种设备选型的计算公式,经计算后选定水力机械,确定合适的泵和风机的型号。将数据汇总编制成excel表格形式。
风机盘管、水泵及附属设备等设备的选型计算及确定型号。本文来自六$维(论"文`网,毕业论文 www.lwfree.cn 加7位QQ324~9114找原文根据所给设计条件以及总冷、热负荷和已经确定的设计方案、设备形式,选择风道以及末端设备、冷热源设备等。在选型中根据不同层,不同功能所需的新风负荷,一层新风机组型号为DX3x8,2至6层选择DX2.5x8的新风机组。风机盘管在此次设计中根据计算我选择了4个型号,主要为FP-10WA和FP-8WA和FP-14WA和FP-16WA。
 
Total Design
General Information Of Design:The building is located in Shanghai, tthe Complex building is about 72 meters high, is a comprehensive building, Complex building construction area of 6696 square meters, including air conditioning area of 3206 square meters. 18 ground floor main building, Complex building is given priority to with offices and meeting rooms. The design of interior design reference of indoor calculation parameters, preliminary design, are: Summer: dry bulb temperature of 26 degrees, relative humidity of 55%, wind speed ≤ 0.3m / s.
According to the diagram given room number building conditions to determine the load of each room type, room size, window size, envelope heat transfer coefficient, toward the room, the heat transfer area, outdoor weather conditions, interior design parameters. Excel table to the room with the hourly load of statistics calculated, appear to determine the maximum load and maximum load value of time. According to energy conservation design standards, combined with calculation software, cooling coefficient method used throughout the hotel on the hourly cooling load calculations. After calculated, the total cooling load of the hotel as 458.5KW, maximum load moment in the evening 21:00.
By the calculated total load, to determine the form of systems, this design, I will layer, layer by layer, and 10 unified district water system; layer 2-6 rooms divided into two area water system, using fans coil plus fresh way. Combining the characteristics of the building, in the chilled water system to determine the choice I closed, vertical differentiation process, double-control, single-stage pump, variable flow system, this air conditioning system has a simple structure, the initial investment is small, difficult to produce pipeline dirt and corrosion, the advantages of smaller pump power. Design will be air-conditioned room set at the top, deal with air-cooled, use air-cooled screw air conditioning units, model cuw80e5y.
According to the given design parameters and calculated parameters, find the appropriate data manual for the system of hydraulic calculations, hydraulic calculations, according to already draw system sketch, determine the system's most unfavorable pipe, mark the most unfavorable pipe node , by assuming the hydraulic sub-flow method calculations on the diameter of the pipe and the piping of the hydraulic losses, hydraulic loss for pipe larger diameter pipe to adjust, come to a reasonable total water along the way loss. Based on the calculated hydraulic losses along the way, a reasonable estimate of the share of local head loss, determine the total water loss, according to a variety of equipment selection formula is calculated for selected machinery, pumps and fans to determine the appropriate model. Excel summary data compiled in tabular form.
Fan coil, water pumps and ancillary equipment such as equipment selection and determine the model calculation. According to the design conditions and the total cooling, heat load and the design have been identified, equipment form, select the air duct and the terminal equipment, cold and heat source equipment. Selection based on different levels in different functional requirements of the new wind load, one layer of fresh air unit model DX2.5x8, 2 至6th floor room selection DX3x8 new air unit. Fan coil in this design I chose according to 2 computing models, mainly FP-8WA and the FP-10WaandFP-14WADandFP-16WA.目录
