楼宇暖通空调系统工程案例分析与节能优化

楼宇暖通空调系统工程案例分析与节能优化浙江大学硕士学位论文摘要i摘要近年来我国建筑类行业飞快发展，而在世界能源危机不断加剧的情况下，减少建筑能耗势在必行。据统计建筑能耗已经占据社会总能耗的27％以上，其中杭州、上海、北京等一线城市地区已接近40％，且其总量呈逐年上升趋势。能源总消费量的比例从20世纪70年代末的10％，上升到近年的27．48％，其中2／3为暖通空调系统所消耗。在建筑工程中暖通空调系统正在飞速的得以应用，用于暖通空调系统的能耗也将进一步增大，致使我国目前现有空调系统的能耗巨大。国家对于公共建筑的节能也非常重视，2010年6月10日，建设部发出《关于切实加强政府办公和大型公共建筑节能管理工作的通知》，对辖区内的政府办公建筑和公共建筑执行空调温度控制情况至少进行一次专项检查，对不符合《公共建筑节能设计标准》(GB50189-2005)和《公共建筑空调温度控制管理办法》规定的要责令其整改，并向社会公布检查结果。所以对楼宇空调系统的节能优化不仅响应国家的要求，也节约了能源的使用。论文结合阳澄湖维景国际度假酒店暖通空调系统的案例，阐述了阳澄湖维景国际度假酒店的楼宇自控的设计方案，设计了酒店的楼宇自控系统的GUI，优化了酒店的控制系统部分，以实验的形式论证了在满足酒店舒适度的条件下，不同的状态下的COP(CoefficientOfPerformance)的最大比值，实现了酒店空调暖通系统的节能。论文通过对阳澄湖维景国际度假酒店的自控系统的设计和控制系统部分优化，以及使用过程中的对冷冻机组供水温度的控制，达到酒店暖通空调系统在满足同样的舒适度的前提下节能12.85%。关键词：楼宇暖通空调系统设计方案节能分析浙江大学硕士学位论文AbstractiiAbstractChina'sarchitecturalindustryrapiddevelopmentinrecentyears,inthecaseofgrowingworldenergycrisis,reducingbuildingenergyconsumptionisimperative.Accordingtostatisticsofbuildingenergyconsumptionhasaccountedformorethan27%ofthetotalenergyconsumptionofthecommunity,includingHangzhou,Shanghai,Beijingandotherurbanareas,nearly40percent,anditstotalamountincreasedyearbyyear.Theproportionofthetotalenergyconsumptionfrom10percentinthelate1970s,roseto27.48percentinrecentyears,ofwhich2/3fortheHVACsystemconsumption.InArchitecturalEngineeringHVACsystemisrapidlyapplied,theenergyconsumptionfortheHVACsystemwillbefurtherincreased,resultinginourcurrentexistingairconditioningsystems,energyconsumptionishuge.Countryalsoattachesgreatimportancetopublicbuildingsenergy-saving,June10,2010,theMinistryofConstructionissuedanoticetostrengthenthegovernmentofficesandlarge-scalepublicbuildingenergymanagement,theimplementationofairtemperatureontheareaofgovernmentofficebuildingsandpublicbuildingscontrolthesituationatleastonceaspecialinspectionshouldbeordereddoesnotmeetthepublicbuildingenergyefficiencydesignstandard(GB50189-2005)andpublicbuildings,air-conditioningtemperaturecontrolmanagementapproachprovidestherectificationtothepublicregardingtheresults.Buildingenergyoptimizationofairconditioningsystemsnotonlyrespondtotherequirementsofthecountry,butalsosavesenergyuse.ThepapercombinesthecaseoftheYangchengLakeMetroparkResortHVACsystemsontheYangchengLakeMetroparkResortbuildingautomationdesign,designofthehotelbuildingautomationsystem,GUI,optimizedtheMetroparkcontrolsystempartofanexperimentalintheformofhotelHVACsystemenergyconservationtomeettheconditionsofhotelcomfort,themaximumratioofthedifferentstatesundertheCOP(CoefficientOfPerformance).ThroughthedesignandcontrolsystemoftheautomaticcontrolsystemoftheYangchengLakeMetroparkResortpartofoptimization,andcontroltheprocessof浙江大学硕士学位论文Abstractiiiusingthewatertemperatureofrefrigerationunits,HVACsystemstoreachthehotelmeetthesamecomfort,energysaving12.85%.Keywords:thebuildingHVACsystem,design,energy-saving,analysis浙江大学硕士学位论文目录I目录摘要...............................................................................................................................iAbstract........................................................................................................................ii图目录........................................................................................................................III表目录.......................................................................................................................IV第1章绪论................................................................................................................11.1研究背景..............................................................................................................11.2研究现状与问题..................................................................................................21.3研究内容..............................................................................................................31.4论文构架..............................................................................................................3第2章阳澄湖维景国际度假酒店楼宇自控方案....................................................42.1系统概述..............................................................................................................42.2设计依据..............................................................................................................42.3总体设计..............................................................................................................42.3.1系统组成.......................................................................................................42.3.2系统选型.......................................................................................................52.3.3点位表...........................................................................................................62.4详细设计方案....................................................................................................132.4.1系统结构.....................................................................................................132.4.2冷热源系统控制.........................................................................................142.4.3空调系统控制...
