该设计按照建筑结构及其要求制定空调方案，力求能够满足使用的要求，既能满足办公室舒适性，此外还要满足空调设计的科学合理性和经济性，比如所有房间内选择的风机盘管均为同一品牌（格力），方便采购。

本设计是真实性课题的典例，有理论的分析计算，有中央空调的选择论证，有实际的绘图，是一个完整的工程设计实例。设计计算主要有冷负荷的计算，送风量的计算，管路的计算等等。冷负荷的计算确定了各个房间的空气状况和调节条件，以及整个工程的负荷量。是确定室内空调调节方案的主要数据。也是选择冷水机组最主要的参考数据。送风量和管路的计算是面向实际设备和管路的数据资料，都是整个设计的基础。此外还对一些细节问题加以论证思考并列出解决方案。比如管道的腐蚀问题，保温问题，材料的选择等等。整个设计中尽力能完善的解决工程中的实际问题。

General design specification With the rapid development of national economy, people gradually realize the building environment for human life, working efficiency and product quality plays a very important role.People to the requirement of modern architecture, not content to shelter from the rain, also should have a suitable temperature and humidity, fresh air, quiet and comfortable environment.Therefore, air conditioning technology has gradually developed into a maintain good indoor environment an essential technology.On this basis, the air temperature, humidity, wind speed and cleanliness of artificial regulation, for the air conditioning system design, in order to satisfy the human body comfort requirements, improve the work efficiency of people.

The content of this design include: selected appropriate air conditioning system type and to determine the design scheme, calculation section is also very important, for example: air condition cold load calculation; Determination of the air conditioning system pision and system solutions; cold source; design and calculation of wind system; indoor air wind flow forms of organization with the selected; water system design, layout and hydraulic calculation; air duct system and water system, insulation layer design. In addition, it is necessary to carry on the treatment equipment of the end of the air conditioning and the selection of the auxiliary equipment and the equipment room. Need to choose the appropriate air conditioning units and terminal equipment according to the architecture of the choice of air conditioning system and the characteristics of the office building, reasonable arrangement of ceiling endogenous wind pipe and water pipe position. And according to the choice of air conditioning unit matching the appropriate auxiliary equipment: chilled water circulating pump, cooling water circulation pump, open water tank, cooling tower, and the corresponding pipe wind pipes, valves, and so on.

    Duct pipe hydraulic calculation;Construction drawings.Written instructions.Reference literature mainly has “The practical heating air conditioning design manual(second edition)”; “The civil building heating ventilation and Air conditioning design standard (GB50736-2012)”;“The code for fire protection design of buildings (GB50016-2014)”, etc.

Henghua business building is set office, accommodation, leisure entertainment, catering is a body business building.Building a total of fifteen layers, a total construction area of 10734.40m squared, with a total height of 49.5m, 3.3m per floor. It belongs to high-rise building. By the calculation, building a total cooling load of 1425.93 kW,fresh air cooling load of the total of 713.26 kW. Maximum cold load value appears in 16:00.

The first floor of the building and the fifth floor because there is a large area of the lobby and dining area, so the whole air system. The rest of the floor due to the different functions of the room to use a different time, so the use of fan coil plus fresh air system, easy to control. The design area of all air system cooling capacity were 7700.5m3/h and 9171m3/h, so the a horizontal modular air conditioning units, produced by the Jingjiang Chunyi air conditioning refrigeration equipment Co., Ltd., model of ZK60, rated air flow 60000m3/h. Fan coil units of the rest of the floor are made of Gree suction type concealed in the top models, taking into account the convenience decoration procurement, selects the FP-8XD, FP-10XD, fan coil FP-12.5XD these three kinds of models, the model of FP-8XD a total of 97 and Taiwan, FP-10XD types of a total of 139 units, the type of FP-12.5XD a total of 91 and Taiwan. The median total cooling capacity was 3.944Kw, 4.59Kw, 5.721Kw, respectively.
