摘要：本毕业设计的内容是长沙市商业综合楼暖通空调工程（1-4楼商业区）的设计。建筑概述：项目位于长沙市，地上4层，总建筑面积为14547.69㎡，高度19.3m。根据土建资料以及长沙地区的气象参数，结合用户对空调系统的使用要求，严格按照《采暖通风与空气调节设计规范》等的指导要求进行设计，内容包括负荷计算、系统形式的确定、空调水系统和风系统以及气流组织的设计和计算、空气处理设备和末端装置的选型以及施工图的绘制等。根据各房间大小、功能等具体情况选取不同空调方案，例如面积较大的大厅和商铺等采用全空气系统，设置散流器平送的形式，这样能有效的进行除湿并能满足风量要求，而对于一般的办公室，因为其面积较小，多采用风机盘管加新风系统侧送的气流组织形式，主要是考虑了其占地小、噪音低和便于控制等优点。本设计的水系统采用了垂直方向的同程式，水平方向采用异程式的形式。根据长沙市当地的特点，我选用了溴化锂吸收式冷（热）水机组，这样不仅可以夏季供冷，冬季还可以供热。此外，我还对空调系统的防腐保温以及消声减震等进行了简单的设计。70605

Changsha City Commercial Building Building HVAC Project (1-4 Floor Business District) Design

Abstract: The content of the graduation design is the design of Changsha commercial building HVAC project (1-4 building commercial area). Building Overview: The project is located in Changsha City, the ground 4 layer, with a total construction area of 14547.69 square meters, height 19.3m. According to the civil engineering data and the meteorological parameters of Changsha area, combined with the user's requirements for the use of air conditioning system, in strict accordance with the "heating ventilation and air conditioning design specifications" and other guidance requirements, including load calculation, system form, air conditioning water system The design and calculation of the wind system and the airflow organization, the selection of the air handling equipment and the end device, and the drawing of the construction drawing. According to the size of each room, function and other specific circumstances to choose a different air-conditioning program, such as the larger lobby and shops such as the use of all-air system, set the diffuser flat delivery form, which can effectively dehumidify and meet the air volume requirements, and For the general office, because of its small size, the use of fan coil plus fresh air system side of the air flow organization, mainly to consider its small footprint, low noise and easy to control and so on. The design of the water system using the vertical direction of the same program, the horizontal direction of the use of different forms. According to the local characteristics of Changsha City, I chose the lithium bromide absorption of cold (hot) water unit, so that not only can be cold in summer, winter can also heat. In addition, I also air conditioning system, anti-corrosion insulation and noise reduction, such as a simple design.
