1室内空调通风工程设计前言空气调节(AirConditioning)的意义在于“使房间或封闭空间的空气温度、湿度、洁净度和气流速度等参数达到给定的要求技术”或“使空气处于某种正常状态”。据此通过一定的方法使某一空间的环境达到某种生产工艺的要求或是某舒适居住环境的要求。随着科技的发展和各种现代技术发展有时还要求对空气的压力、成分、气味及噪声等进行调节与控制。由此可见,采用技术手段创造并保持满足一定要求的空气环境,乃是空气调节的任务。2摘要本次设计内容包括:空调冷负荷的计算;空调系统的划分与系统方案的确定;冷源的选择;空调末端处理设备的选型;风系统的设计与计算;室内送风方式与气流组织形式的选定;水系统的设计、布置与水力计算;最后,根据设计的过程及计算结果运用CAD绘制标准层空调系统平面图,水系统图、空调机房平面图以及冷冻机房平面图。本设计依据有关规范考虑节能和舒适性要求,设计的空调系统首层采用全空气通风系统,标准层采用风机盘管—新风系统。关键词中央空调;全空气;风机盘管;新风关键词:冷负荷,空调水系统,全空气一次回风系统,风机盘管加新风系统3AbstractThedesignelementsinclude:thecoolingloadcalculation;air-conditioningsystemsdivisionandprogram;coldsourceselection;airconditioningterminalequipmentselection;airsystemdesignandcalculation;indoorairwithairformoforganizationselected;watersystemdesign,layoutandhydrauliccalculations;Finally,accordingtothedesignprocessandcalculationresults,theuseofCADdrawingstandardlayerofair-conditioningsystemplan,watersystem,air-conditionedcomputerroomfloorplan,andchillerplantplan.Thisdesigninaccordancewiththerelevantspecificationstoconsiderenergyefficiencyandcomfortrequirementsofthefirstfloorofthedesignofair-conditioningsystemwithfullairventilationsystem,thestandardfloorfancoilunits-anewwindsystem.Keywordscenttralairconditioning;allairsystem;fancoilunits(FCUs);freshairsystem4目录第一章绪论............................................................................................................................................11.1课题背景................................................................................................................................................11.2空调设计的重要性................................................................................................................................11.2.2节能空调设计是建筑节能的重要环节.............................................................................................11.2.3防火排烟与安全卫生是空调设计的重要任务..................................................................................2第2章负荷的计算..........................................................................................................72.1空调负荷的构成....................................................................................................92.1.1房间冷负荷的构成....................................................................................92.1.2房间湿负荷的构成....................................................................................102.1.3房间热负荷的构成..................................................................................102.1.4空调总冷负荷的确定..............................................................................102.2空调冷负荷计算公式........................................................................................102.2.1负荷计算说明............................................................................................102.2.2外墙和屋顶的冷负荷............................................................................112.2.3透过玻璃窗的日射得热形成的冷负荷.....................................................1252.2.4玻璃窗传热冷负荷............................................................................122.2.5照明散热形成的冷负荷.............................................................................132.2.6人体冷负荷..............................................................................................142.2.7室内其他的热源显热冷负荷................................................................152.3空调湿负荷计算公式..........................................................................................16第5章送风量计算及空气处理过程........................................................................185.1新风量的确定............................................................................................................185.2空气处理过程及状态参数..................................................................................185.2.1全空气一次回风空调系统........................................................................185.2.2风机盘管加新风系统...................................................错误!未定义书签。第6章气流组织............................................................................................................236.1气流组织方案.............................................................................................................236.1.1空调房间气流组织的形式.........................................................................236.1.2空调房间送回风口的型式.........................................................................246.1.3送回风口的布置方式.................................................................................256.2气流组织计算............................................................................................................256.2.1一层商场气流组织计算和风口选型............................错误!未定义书签。6.2.2小空间气流组织计算和风口选型................................错误!未定义书签。第10章空调系统的消声和减振..................................................................................2610.1空调系统的消声.................................................................................................2610.2空调系统的减振.................................................................................................28第11章空调系统的保温和防腐....................................................................
