摘要本设计的内容是空调系统设计。想要达到的效果是，通过计算，为在该建筑中工 作、生活的人员提供舒适的、健康的环境，设计出合理的空调系统。

本设计的系统方案选择如下：一、二层的大厅和餐厅由于面积较大，并且工作时 间相对一致，故选择一次回风的全空气处理方案；而三层客房由于面积小、人员逗留 时间长，采用风机盘管加独立新风系统。

具体计算步骤和方法如下：冷负荷用谐波法的工程简化算法计算。空调机组、风 机盘管以及新风机组的选型在空调冷负荷计算完成的基础上进行。新风机组根据新风 量和新风负荷来确定。接着进行水管和风管的水力计算。水力计算采用假定流速法, 由此即可确定水管和风管的管径及布置。84144

本次设计的主要内容包括：各房间负荷计算；空调系统的确定；送风量的计算； 风机盘管的选型；水管和风管的水力计算和选型；以及系统的维护和节能措施等内容。

毕业论文关键词：全空气系统，风机盘管加独立新风系统，空调负荷，设备选型，水力计算

Abstract The content of this design is the design of the air conditioning system, the purpose is to design a reasonable, energy-saving air-conditioning system, to provide a comfortable working and living environment for the indoor personnel。

The design of the system options are as follows:because the halls of first and second floors have large areas and the working time is relatively consistent,the air conditioning system uses entire air system。Because of the small area and long stay time,three floors of guest rooms use fan coil plus fresh air system。

The detailed calculation steps and methods are as follows:the calculation method of cold load is engineering simplification algorithm of harmonic method。The selection of air conditioning units, fan coil unit and fresh air unit are based on the result of air condition cold load。Fresh air unit is determined by the fresh air volume and the fresh air load 。 Then we completed the hydraulic calculation of pipe and duct 。Assumed flow velocity method was used in hydraulic calculation, which can be used to determine the diameter and arrangement of pipe and duct。

The main contents of the design include: load calculation of  the  room;  air conditioning system determined; content of air volume calculation; the selection of fan coil; pipe and duct hydraulic calculation and selection and system maintenance  and energy saving measures。

Keywords: entire air system , fan coil unit plus independent fresh air system , air conditioning load ,equipment Selection , hydraulic calculation
