设计的主要工作为：论文网
1. 完成冷热负荷计算、送风量计算；
2.完成空调系统形式选择和设备选择计算；
3.完成风管或水管的水力计算及设计；
4. 进行冷水机房设计和各种设备选型；
5. 绘制图纸。
2. 设计原则
2.1 空调系统设计原则
随着社会的发展，人们对舒适性要求的提高，对空调舒适性要求很高。空调再也不是之前传统意义上单纯为了调节房间温度的机器，除了温度之外，我们还要考虑湿度、空气洁净度、人体皮肤舒适度等等。因此，我们空调设计人员在设计过程中要考虑以上各种要求。随着科技的发展，空调制造业也针对人们的各种个性化要求对自己的工艺进行了改革，出品了各种针对不同需求的功能性空调。
设计中商铺、办公室等小空间可以利用风机盘管加新风系统，可以针对不同空间不同要求调节空气温度。内部区域较大的大空间多可以采用全空气系统，管理简单，过渡季节节能效果好。
2.2 风管系统的设计原则
多层建筑的系统划分应根据各层平面布置和机房的位置等条件而定，尽量做到风管布置合理，系统运转灵活而经济，空气调节系统不宜过大，以便于调节和减少噪声。而且要配合土木施工单位，做好风管预埋，不得影响土木建筑结构。
2.3 水管系统的设计原则
力求水力平衡；防止大流量小温差；水输送系数要符合规范要求；变流量系统宜采用变频调节；要处理好水系统的膨胀与排气；要解决好水处理与水过滤；要注意管网的防冻和保暖。
General Information Of Design
1. Design task
The design of the Shanghai Lifeng Central Air-conditioning System design, located in Shanghai.In order to be able to independently control the air-conditioning in each room to run and save the electricity, air-conditioning fan sites are designed to The new system increases the wind pipe. Conference room, office, lounge, corridor ventilation systems are designed to give mechanical ventilation mainly natural way into the exhaust as a supplement.
System choose single screw water chiller. The closed air conditioning water system, two different program control.
Cooling tower is set on the roof, cold hot water units and cooling water pump, chilled water pump in the basement..
The main work of the design
1. The completion of hot and cold load, the air quantity;
2. The completion of the form of air-conditioning system selection and choice of computing equipment;
3. The completion of the wind pipe or pipes of the hydraulic calculation and design;
4. Mapping system air duct or water pipe plan, drawing water or air conditioning system diagram.
5. For cooling the engine room design and equipment selection, including chillers, pumps and other equipment selection.
2. Designing Principle
2.1 The designing principle of air conditioning system
With the development of the society, people's requirement for comfort, for comfort air conditioning is very demanding. Before air conditioning is no longer in the traditional sense simply in order to adjust the room temperature machine, in addition to the temperature, we also consider the humidity, clean air, human skin comfort and so on. Therefore, our air conditioning design personnel in the design process should consider above all kinds of requirements. With the development of science and technology, also in the light of the personalized requirements of the people in manufacturing air conditioning has carried on the reform of its own technology, according to different demand produced all kinds of air conditioning.
