酒店空调设计论文

哈尔滨理工大学学士学位论文-I-上海锦江酒店空调系统设计摘要本次设计的内容是上海锦江饭店中央空调系统的设计。首先，查阅设计地点的地理资料得出相应的气象条件，根据当地具体的条件以及维护结构计算夏季整个系统的冷负荷。考虑经济因素，客房采用目前广泛使用的一次回风加新风的风机盘管系统，一层采用全空气一次回风系统。新风由新风机组处理到室内焓值，通过送风管道，送至风机盘管后部，同室内回风混合后经风机盘管送出，改善室内卫生条件。根据计算而得的各系统所需冷量，选取冷源为风冷式冷水机组，水系统管路采用同程式布置，以提高水力稳定性，使流量均匀分配。系统采用膨胀水箱补水和定压，冷冻水经冷水机组处理后进入风机盘管和表冷器等末端设备。同时，在相应的计算过程中，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。通过本次设计使室内环境得到改善，达到了设计要求。关键词中央空调；风机盘管；新风系统；水系统；室内焓值哈尔滨理工大学学士学位论文-II-DesignofCentralAir-ConditioningofJinjiangHotelinShanghaiAbstractThesubjectofthisdesignisthedesignofcentralair-condtioningofshanghaihotelinHarbin.First,gettingthemeteorologicalconditionwithlookingupthegeographydata.Accordingtotheidiographicconditionandmaintenancestructuretocountingcoolloadinsummer.Toeconomizeoncost,roomsforcustomersadoptingthecommonformofdealingair,thatisfan-coilunitsystemswithcentralairsystem.Thefirstfloorisequippedwithall-aironceair-returnsystem.Freshairisdealedtotheenthalpyvalueofindoorbyfreshairhandlingunit,andbywindduct,issenttothebackofthefan-coilunit.Accordingtocoldcapacity,twocoldwaterunitswerechosentobecoolingsource,andinordertoraisethewaterpowerstability,makingtheevendistributionofvolumeofflow,thesystemusesthewatertankexpandingtosupplywaterandstabilizethepressure.Coolantisprocessedintherefrigerantunit,andthenentersintoterminalequipments,suchasfan-coilandsurfacecoolingunit.Atthesametime,inprocessofcaculating,thestandardfloorair-conditionsystemdraing,andthewaterpipesystem、theair-conditionroomaswellasrefrigeratorhousedrawingweredrawnbyus.Thedesigingmaketheenvironmentofindoorimproved.Hasachievedthedesignrequirement.Keywordscentralairconditioning;freshairsystem;watersystem;theenthalpyvalueofindoor哈尔滨理工大学学士学位论文-III-目录摘要·······················································································IAbstract···················································································II第1章绪论···············································································11.1前言·················································································11.2课题背景···········································································11.3宾馆空调设计总论·······························································11.4设计任务与意义··································································2第2章空调冷负荷计算··································································32.1地理资料···········································································32.2土建条件···········································································32.2.1建筑概况······································································32.2.2围护结构概况································································32.3选取其他设计条件·······························································42.4空调冷负荷的计算·······························································42.4.1夏季建筑围护结构的冷负荷总述·······································42.4.2围护结构的冷负荷·························································42.4.3室内热源形成的冷负荷···················································52.5空调房间内的散湿量计算······················································62.6围护结构内制冷系统总冷负荷················································72.7冷负荷计算举例··································································72.7.1已知条件······································································82.7.2冷负荷计算···································································82.7.3冷负荷计算汇总····························································112.8湿负荷计算举例·································································122.9本章小结··········································································13第3章空调方案的选择及风量计算···················································143.1空调系统分类及特点··························································143.2风量计算·········································································153.3其他空调房间风量计算·······················································173.4本章小结·········································································17第4章空调设备的选择及校核························································184.1空调设备的分类································································184.2空气处理机组的选择··························································19哈尔滨理工大学学士学位论文-IV-4.2.1客房新风机组的选择·····················································194.3空调设备的较核································································194.4其他系统的空气处理机组选择及校核·····································204.5本章小结·········································································20第5章空调风道管路设计计算························································215.1风系统设计要点·································································215.2风道管路的设计方法···························································215.3沿程阻力和局部阻力计算·····················································225.4新风管道水力计算举例························································235.5本章小结··········································································25第6章空调系统冷源设计··············
