需要注意的是空调系统的设计中首先要考虑到防火分区和防排烟区的分区。空调系统的风道不能贯穿两个分区，如果需要跨区风道需要进行防火，防排烟的设计。
办公楼的主要负荷是人员热湿负荷、照明负荷，办公设备负荷以及新风热湿负荷。因为围护结构的传热负荷相对于人员，照明和设备小的多所以可以忽略掉。再考虑到建筑的地点和当地的空调设计参数和规范，设备的选型和负荷计算要在满足要求的情况下尽力做到节能和减排的设计。本空调系统的设计思路是先按照概算方式，进行负荷来概算每个空调分区的负荷，从而进行风机盘管和新风系统的选型。选型好了设备后根据设备的额定量来进行房间的风口和水路系统的布置。根据布置来进行气流组织的计算，经过校核来验证风口的布置位置，个数，喉部速度是否满足要求。如果校核的结果没有满足要求者需要再次进行校核，通过改变风口的速度，个数，改变散流器的面积，水平射程，垂直射程来满足房间的气流组织的校核。通过负荷的初步设计来进行准确负荷计算。计算负荷时需要注意计算的负荷是理想的状态下所需要和理想方式能供给的负荷，但是设备和环境也会进行热量湿量的交换，设备与设备的连接也会存在误差和人员安装时的错误操作造成的设备口的漏风等原因，所以计算时需要适当的乘与修正系数。还需要考虑到设备满负荷运行时所能提供的负荷是否能满足负荷的最大值。毕业论文
通过以上的负荷计算，结合建筑的特点合理的布置管道和空调水路。
General design information
My graduation design content is shadow sheng Shanghai center E area air conditioning water system design and system design. This project for the comprehensive shopping malls, with a total construction area of 270630 square meters, covers an area of 2330 square meters standard layer, each layer of building height of 4 meters. There are three layers in the basement, 64 stories on the ground. Air conditioning load is mainly composed of palisade structure heat load, the lighting load and fresh air load, equipment load and load, etc. I was responsible for the air conditioning water system design and system design is 37 floor office building design.
Need to be aware of is the first consideration in the design of air conditioning system to the fire and smoke control area partitioning. Air conditioning system of air duct can't through two partitions, if you need any inter-district duct to fire, smoke control design.
Office building is the main load of the heat and moisture load, light load, office equipment load and fresh air heat and moisture load. Because the heat load of palisade structure relative to personnel, lighting and equipment, much smaller so can be ignored. Again considering the construction site and the local air conditioning design parameters and specification, equipment selection and load calculation in the case of meet the requirements to achieve the design of energy conservation and emission reduction. The air conditioning system design is in accordance with the first estimate, partition to load to estimate each air conditioning load, and thus for the fan coil units with fresh air system selection. After the selection of the equipment according to equipment capacity rating for room arrangement of tuyere and waterway system. According to the arrangement of the air distribution is calculated, after checking to verify the position of the tuyere layout, number of throat velocity whether meet the requirements. If the check result does not meet requirement need to check again, by changing the speed of the tuyere, number, change the area to the scattered, level range, the vertical range to meet the check in room air distribution. Through the load of the preliminary design for accurate load calculation. Need to pay attention to when load calculation load is the ideal state of need and the ideal way to supply the load, but the equipment and the environment also can exchange heat moisture content, equipment and equipment connection error exist and personnel when installing the equipment caused by the improper operation of mouth of air leakage, so need proper multiply and correction coefficient calculation. Also need to consider to the device at run time whether can provide load can meet the maximum load.
