广州市移动通信综合办公楼空调系统设计

广州市移动通信综合办公楼空调系统设计-I-摘要本设计对象是广东省广州市移动通信综合办公楼空调系统的设计。该高层建筑位于广东省广州市，从地下一层到地上8层，高度25.6m，空调区域面积6312m2。房间类型主要有办公室，会议室，计算机房，电力机房，活动室、营业大厅等。其中地下室主要为设备机房，一、二层为营业大厅和办公室,三—五层为机房层,六层为会计室和计算机房，七层为活动室,八层为值班室。本论文设计范围为：空调房间负荷计算，空气处理过程，空调方案的确定，气流组织设计，空气-水系统的水力计算，设备选型。本设计根据广东广州地区气象资料和建筑房间类型，采用风机盘管加新风系统。所采用风机盘管为卧式暗装两管制。风机盘管采用散流器平送风气流组织方式。每层机房采用新风机组独立供给本层各房间新风，每层一个新风机组。空调冷源采用冷水机组设置在地下室。冷却塔设置在8层楼顶。论文最后对整个设计进行了总结，并对有待于进一步研究的问题进行了概述，对今后的设计工作提出了一些建议。强调空调设计应尽量满足业主的要求及节能规范。本设计依据参考并执行国家相关标准及规范。关键词：办公楼空调、风机盘管、负荷计算、水力计算沈阳工程学院毕业设计（论文）-II-ABSTRACTThisdesignobjectistheguangdongprovinceguangzhoucityamobilecommunicationsintegratedofficeairconditioningsystemdesign.Thehigh-levelbuildingislocatedinguangzhoucity,guangdongprovincefromundergroundlayertotheground8storeys,highly25.6m,airconditioningareato6312m2.Roomtypeshavemainlyoffice,conferenceroom,computerroom,balconystores,electricalroom,activityroom,businesshall.Includingthebasementforequipmentroom,one-two-storyhallforbusinessandoffice,three-five-storyengineroomlayer,sixfortheaccountingroomandcomputerroom,sevenactivityroom;,eightforthedutyroom.Thedesignscopeofthispaperare:air-conditionedroomloadcalculation,theprocessofairhandling,air-conditioningprogram,theairdistributiondesign,theair-watersystemhydrauliccalculation,equipmentselection.ThedesignaccordingtothetypeofweatherdataandbuildingroominGuangzhou,fancoilplusfreshairsystem.Fancoilusedforthehorizontalconcealedcontrols.Thefancoilsideairdiffuserlevelairfloworganization.Oneachmachineroomwiththefreshairhandlingunittoanindependentsupplyoffreshairinthislayerineachroom,eachfloorofanewairhandlingunits.Theairconditioningcoolingsourcechillersetinthebasement.Thecoolingtowerissetinthe8thfloorroof.Paperfinallysummarizesthedesignofthewhole,andneedstobefurtherstudiedaresummarized,theproblemoffuturedesignwork,someSuggestionswereputforward.Emphasizeairconditioningdesignshouldtrytomeettherequirementofownerandenergy-savingnorms.Thisdesignbasedonreferenceandexecuterelevantnationalstandardsandspecifications.Keywords：officebuildingairconditioning,fan-coil,loadcalculation,hydrauliccalculation广州市移动通信综合办公楼空调系统设计-III-目录摘要......................................................................IABSTRACT...................................................................II前言......................................................................III第一章基础资料.............................................................21.1设计依据............................................................21.2工程概况和设计内容..................................................21.2.1工程概况......................................................21.2.2设计内容......................................................21.3设计说明............................................................31.3.1室外设计参数..................................................31.3.2室内设计参数..................................................31.3.3设计对象建筑热工参数..........................................3第二章负荷计算.............................................................52.1空调冷负荷计算原理..................................................52.2冷负荷计算..........................................................52.2.1外墙和屋顶的冷负荷............................................52.2.2外玻璃窗瞬变传热引起的冷负荷..................................52.2.3外玻璃窗日照得热引起的冷负荷..................................62.2.4人体散热形成的冷负荷..........................................62.2.5灯光照明形成的冷负荷..........................................72.2.6设备散热形成的冷负荷..........................................72.2.7确定空调房间的冷负荷..........................................72.3新风负荷...........................................................132.3.1新风量的确定.................................................132.3.2新风负荷的确定...............................................132.4负荷计算总表.......................................................14第三章空调系统方案的确定..................................................173.1空调系统方案的选择.................................................173.1.1空调系统的划分原则...........................................173.1.2常用空调系统分类及方案的比较.................................173.2送风方案的确定.....................................................20第四章风量的确定..........................................................224.1计算依据...........................................................224.2风机盘管加新风系统风量的计算.......................................234.2.1风机盘管加新风系统计算.......................................23沈阳工程学院毕业设计（论文）-IV-4.2.2各房间风量冷量汇总...........................................23第五章气流组织设计计算....................................................275.1送风口形式的选择...................................................275.2散流器平送风设计步骤...............................................275.3散流器计算.........................................................27第六章风管水力计算........................................................316.1风道的布置和制作要求...............................................316.2风管水力计算方法...................................................31第七章水管水力计算........................................................377.1水系统的设计选择...................................................377.2水管水力计算....................
