暖通空调设计 毕业设计说明书.docx

-- I 摘要暖通空调设计主要是对室内热环境、空气品质进行设计,这项工作必须在充分了解建筑对暖通空调的要求和暖通空调系统及设备对建筑及其它设施的影响的基础上才可以顺利进行。设计主要内容包括:空调冷热负荷的计算;送风量和新风量的确定;空调系统的划分;空调方式的选择;空调末端处理设备的选型;冷热源的选择;风系统的设计与计算;风管系统的设计;室内送风方式与气流组织形式的确定;水系统的设计与水力计算;管道的保温设计;防排烟的设计;消声防振设计等。本工程位于青岛市,是集图书与办公为一体的建筑。该建筑地下一层,地上八层。机房设于地下层,其地下层主要为报告厅,其余还有贵宾室,一至六层大多为借阅室和书库,七八层则主要为办公室。地下一层层高 ,一层层高 ,其余 地上总层高 36m 。该建筑占地面积约 ㎡,建筑面积约为 40058 ㎡,空调面积约 31427 ㎡。通过负荷计算得本建筑夏季总冷负荷 ,冷负荷指标 / ㎡;冬季总热负荷为 ,热负荷指标为 77w/ ㎡。由于青岛属于寒冷地区,有市政集中供热,结合其建筑特点,夏季选用离心式冷水机组供冷,冬季选用水水板式换热器换热。在本设计中,除地下室报告厅采用全空气一起回风处理方案,其余皆采用风机盘管加新风系统。从节能的角度考虑,全空气采用采用露点送风,空气处理机组设在该层的空调机房内,新回风经集中处理后送入各空调房间。其余的风机盘管加新风系统中,将室外新风处理到室内空气焓值的状态, 不承担承担室内负荷。新风由新风机组单独送入每一个房间。风机盘管送风选用下送式,安装形式为卧式暗装。关键字:空调设计,全空气系统,风机盘管系统,冷水机组-- II Abstract HVAC design is mainly for indoor thermal environment and air quality, however this work must put fully awar ing of the requirements for HVAC and HVAC systems and equipment for construction and other facilities as this way,the design can be programmed smoothly. The study content mainly includes: cooling and heating load calculation;the determination of the supply air volume and the fresh air volume;the air- conditioning system division;the selection of modes of air conditoning system;the selection of air conditoning equipment;the selection of the cold and heat source;the design and caculation of the air system;the design of the air duct system; the determination of air supply mode and air distribution mode;the design and the hydraulic calculation of the water system; the thermal insulation design of the pipeline, the design of the smoke prevention and exhaust and the design of noise elimination and vibration prevention. This project is Qiao Library and administration building air conditioning system design, isa collection ofbooks and office asone of the building. The building underground layer, the ground layer eight. Room will be located in the basement, the basement mainly report hall, the VIP room, one to six layers
