设计选型手册B系列直热循环型热泵热水机组三、产品安装1、安装注意事项l工程的设计、安装，必须由有资格的专业人士，根据相关法律、规章，结合本说明书进行。l在不同工况下，机组产水量会有所不同。因此，机组的进出水管管径，请根据机组额定流量的两倍及推荐的流速来计算确定。2、安装位置l安装地点必须足以承受热水机的重量，且运行噪声及排出空气、冷凝水不会影响到邻居。l不可安装在有易燃易爆物品或者严重灰尘、盐雾等污染性空气的地方。l通风良好，有足够的维修空间和进风空间，进出风口无障碍物，保证气流循环畅通无阻。在空气污染和酸雨较严重及空气含盐较多的地区，为防止锈蚀而降低热水机使用寿命，在不妨碍空气流通的情况下，应设置遮阳篷。l便于安装连接管和进行电气连接的地方。3、机组安装l热水机必须水平安装在水泥墩或者槽钢上，并用M12螺栓固定支撑脚，四角安装减震弹簧或者橡胶减震垫，以满足噪声及震动的要求。在修筑水泥墩时，地脚螺钉必须高于固定位置50㎜以上，并做好接水盘，排水沟等，确保排水流畅。l热水机搬上水泥墩上之前，放20㎜厚的橡胶垫片，起防震减振作用。将热水机搬上水泥墩，压住垫片，然后用扳手打上四个地脚螺钉，一定要打紧打牢，并确保水平安装，安装后倾斜角度不大于5°。l多台机组安装在一起时，一定要保证机组有足够的维修、换热空间，严禁机组之间气流短路，否则会导致机组制热效果下降，严重时会损坏机组。l如果热水机系统不处于建筑物上避雷系统的保护中，应按照国家现行标准《建筑物防雷设计规定》（GB50057-94-2000版）的要求，增设避雷措施。4、管路连接l所用管道推荐采用塑料管道（如PPR管、PVC管等），但应考虑主机与水箱之间管道的伸缩问题。lmodelchordlengthmustnotbelessthan2m,foreachofthespecificationsofthetankproduction2.Linearmodelmustbelessthan1M.Measurementofweldangulardeformationofarcmodel,itschordlengthmustnotbelessthan1M,making2blocks.PrecastprocessinaccordancewiththeSetupinordertomeettherequirements,prefabricatedplatesshouldmakegoodmarks,respectivelyinordertofacilitatesubsequentinstallation.7.2.4dieandthemodelmakingdiemakingduetotankwall,androofthin,findroundHouasstoreinappropriatewillwillproduceddeformation,specialmakingwallBoardandroofdiethea,followingfigurebyshows:modelmakingtankinprefabricatedassembledandthetestprocessinthebyusingofmodelrequirementsfollowing:arcmodelstringlongshallnotislessthan2m,foreachspeciesspecificationsoftankthemaking2block.Linearmodelmustbelessthan1M.Measurementofweldangulardeformationofarcmodel,itschordlengthmustnotbelessthan1M,making2blocks.Samplethicknessδ=0.75metalproduction.Backplaneprecastprecastfloorshouldbecarriedoutaccordingtothedesigndrawings.Bottomrowplatedesignshouldbeenlargedindiameter0.1%~0.2%diametertocompensateforweldingcontraction.Bow-platebuttjointgapshouldbeused(seethefollowingfigure),thelateralclearance,E1shouldbefor6~7mm,E2,shouldbe8~12mminsideclearance.Floordistancebetweenanyadjacentweldsshallbenotlessthan300mm.7.2.5bow-edgeplatesthesizeofdeviationshallmeetthefollowingrequirements:sitetolerance(mm)lengthofAB,CD±2widthdifferencebetweenACandBD,EF±2diagonal|AD-BC|≤37.2.6eachtankfloorshouldbesmoothwithoutmutation,partiallinearmodelcheckforsmoothness,itsclearance≤5mm.7.37.3.1panelwallBoardprefabrication-21- 设计选型手册B系列直热循环型热泵热水机组如果管道采用的是钢管、铜管等金属管道，机组必须连接自带的PPR材料的连接管组件，再通过连接管组件，与金属管相连；如果管道采用PPR、PVC等塑料管，机组可以直接与这些管道连接。各连接处加生料带密封。l机组进水处，必须安装过滤器，防止机组内套管换热器的堵塞,并定期清洗。l系统管路上的电磁阀前一般需安装检修阀，以便日后检修;同时便于系统的清洗,在系统最低处应安装排污阀，最高处应安装排气阀。l水系统配管完成后，应根据暖通空调中有关规范进行水压试漏并排污，确保水管道内清洁，无锈渣等污垢物，以防止堵塞管路及机组内的换热器和水泵，造成机组损坏。l在水系统检漏合格后，应对进出水管及补水管进行保温，以防止热量损失及冬季不用热水机时冻裂管道；各阀门也需要保温。5、外形尺寸KFRS-12ZM/B的外形尺寸：modelchordlengthmustnotbelessthan2m,foreachofthespecificationsofthetankproduction2.Linearmodelmustbelessthan1M.Measurementofweldangulardeformationofarcmodel,itschordlengthmustnotbelessthan1M,making2blocks.PrecastprocessinaccordancewiththeSetupinordertomeettherequirements,prefabricatedplatesshouldmakegoodmarks,respectivelyinordertofacilitatesubsequentinstallation.7.2.4dieandthemodelmakingdiemakingduetotankwall,androofthin,findroundHouasstoreinappropriatewillwillproduceddeformation,specialmakingwallBoardandroofdiethea,followingfigurebyshows:modelmakingtankinprefabricatedassembledandthetestprocessinthebyusingofmodelrequirementsfollowing:arcmodelstringlongshallnotislessthan2m,foreachspeciesspecificationsoftankthemaking2block.Linearmodelmustbelessthan1M.Measurementofweldangulardeformationofarcmodel,itschordlengthmustnotbelessthan1M,making2blocks.Samplethicknessδ=0.75metalproduction.Backplaneprecastprecastfloorshouldbecarriedoutaccordingtothedesigndrawings.Bottomrowplatedesignshouldbeenlargedindiameter0.1%~0.2%diametertocompensateforweldingcontraction.Bow-platebuttjointgapshouldbeused(seethefollowingfigure),thelateralclearance,E1shouldbefor6~7mm,E2,shouldbe8~12mminsideclearance.Floordistancebetweenanyadjacentweldsshallbenotlessthan300mm.7.2.5bow-edgeplatesthesizeofdeviationshallmeetthefollowingrequirements:sitetolerance(mm)lengthofAB,CD±2widthdifferencebetweenACandBD,EF±2diagonal|AD-BC|≤37.2.6eachtankfloorshouldbesmoothwithoutmutation,partiallinearmodelcheckforsmoothness,itsclearance≤5mm.7.37.3.1panelwallBoardprefabrication-21-
