3采暖系統(tǒng)的選擇與確定3.1確定熱媒本次設(shè)計(jì)采用散熱器采暖，系統(tǒng)以95℃/70℃的熱水為熱媒。熱水熱媒具有以下優(yōu)點(diǎn)：1、熱能利用效率高；2、改變水溫好調(diào)節(jié)，更滿足衛(wèi)生需求；3、蓄熱能力高；4、可以遠(yuǎn)距離輸送，供熱半徑大。3.2確定熱源本工程采暖方式為低溫?zé)崴匕遢椛洳膳?，由市政管熱力管網(wǎng)提供。3.3確定系統(tǒng)形式重力循環(huán)系統(tǒng)中水靠其密度差循環(huán)，該作用壓頭稱為重力循環(huán)作用壓頭，不需要外來動(dòng)力運(yùn)行時(shí)無噪聲、調(diào)節(jié)方便、管理簡單，由于作用壓頭小，同等流量時(shí)所需的管徑大，只適合用與沒有集中供熱熱源、對(duì)供熱質(zhì)量有特殊要求的小型建筑物中，本設(shè)計(jì)屬于集中供熱熱源，大型建筑物，不適用于這個(gè)系統(tǒng)。機(jī)械循環(huán)系統(tǒng)中的循環(huán)動(dòng)力主要來自于循環(huán)水泵，大多數(shù)情況膨脹水箱接到系統(tǒng)循環(huán)水泵的入口測，在此系統(tǒng)中膨脹水箱不起排氣作用，所以在系統(tǒng)水平供水干管末端設(shè)有集氣罐，進(jìn)行集中排氣。供水干管的標(biāo)高向集氣罐提升。機(jī)械循環(huán)系統(tǒng)作用半徑大，是集中供暖系統(tǒng)的主要形式。雙管系統(tǒng)是用兩根立管或兩根水平支干管（一根管供水、一根管回水）將多組散熱器相互并聯(lián)起來的系統(tǒng)。雙管系統(tǒng)可單個(gè)調(diào)節(jié)散熱器的散熱量，有利于降低供暖能耗；如在各散熱器進(jìn)出口安裝關(guān)閉閥，則維修和改變散熱器的散熱量時(shí)，不影響其他用戶使用，但消耗管材多、施工麻煩、造價(jià)高。雙管系統(tǒng)用于要求供暖質(zhì)量較高、可單個(gè)調(diào)節(jié)散熱器散熱量的建筑。單管系統(tǒng)分為順流式、跨越管式和分流管式三大類。順流式單管系統(tǒng)，每一立管中熱水依次流經(jīng)各層散熱器，與各層散熱器流量相等，結(jié)構(gòu)簡單;無跨越管、節(jié)省管道;比跨越管式單管系統(tǒng)減少散熱器用量;散熱器支管無調(diào)節(jié)閥，減少閥門費(fèi)用。因此造價(jià)低、施工簡便。但不能單個(gè)調(diào)節(jié)散熱器的散熱量，不利于節(jié)能和提高供暖質(zhì)量?？捎糜诠步ㄖ膹d堂、館所和工業(yè)建筑的車間等建筑面積大、不需對(duì)單個(gè)散熱器的散熱量進(jìn)行調(diào)節(jié)的處所?？缭焦苁絾喂芟到y(tǒng)，與順流式相比散熱器的散熱量可調(diào)，因而可以節(jié)能和提高供暖質(zhì)量。但要增加跨越管、散熱器和兩通調(diào)節(jié)閥門的費(fèi)用，增加系統(tǒng)的阻力損失，安裝稍麻煩。可用于要求單個(gè)調(diào)節(jié)散熱器散熱量的各類建筑中。分流管式單管系統(tǒng)，該系統(tǒng)兼有順流式系統(tǒng)可減少散熱器用量和跨越管式系統(tǒng)可調(diào)節(jié)室溫、節(jié)能的優(yōu)點(diǎn)。而且比跨越管式系統(tǒng)散熱器散熱量的調(diào)節(jié)范圍要大，更加有利于調(diào)節(jié)室溫和節(jié)能。與順流式相比要增加三通調(diào)節(jié)閥門的費(fèi)用，增加系統(tǒng)的阻力損失。是單管系統(tǒng)中最有利于實(shí)現(xiàn)單個(gè)散熱器調(diào)節(jié)的系統(tǒng)。該系統(tǒng)取分流管的流量為零的工況為設(shè)計(jì)工況。垂直式系統(tǒng)大直徑的干管可布置在底層(或管溝)頂棚下或設(shè)備層內(nèi)，立管多，但無水平支干管。便于集中排氣。同一用途房間(例如樓梯間、衛(wèi)生間等)的散熱器可連接在同立管上，便于調(diào)節(jié)、維修，以及維修時(shí)不影響其他房間供暖。水平式系統(tǒng)便于分層或分戶控制和調(diào)節(jié)。大直徑的干管少、水平支干管多、穿樓板的文個(gè)少，有利加快施工進(jìn)度。系統(tǒng)中單獨(dú)設(shè)置膨脹水箱時(shí)，水箱標(biāo)高可以降低。室內(nèi)無立管此較美觀。但靠近地面處布置管道，有礙清掃。水平式系統(tǒng)以往多用于有大面積的廳，堂公用建筑中，近年來用于居住建筑分戶熱計(jì)量系統(tǒng)?？紤]到本工程的實(shí)際規(guī)模和施工的方便性，根據(jù)經(jīng)濟(jì)節(jié)約并滿足設(shè)計(jì)要求的原則，采用機(jī)械雙管下供下回異程式系統(tǒng)，散熱器面積和管道的安裝工作量都最小。該系統(tǒng)具有：1、緩和了上供下回式系統(tǒng)的垂直失調(diào)象;2、安裝供回水干管需設(shè)置地溝;3、室內(nèi)無供水干管，頂層房間美觀等優(yōu)點(diǎn)；但也具有排氣不便等的缺點(diǎn)。

4確定散熱設(shè)備4.1散熱器的選用原則1、按產(chǎn)品標(biāo)準(zhǔn)中的規(guī)定選用散熱器的工作壓力，會(huì)更準(zhǔn)確和適應(yīng)散熱器行業(yè)發(fā)展的需要。2、散熱器的散熱性、清掃和裝飾要求。3、采用鋼制散熱器時(shí)，必須注意防腐，結(jié)垢的問題。4、熱工性能方面的要求是散熱器的傳熱系數(shù)越高，說明散熱器散熱性能越好。4.2對(duì)散熱器要求熱功性能方面的要求：散熱器的傳熱系數(shù)越高，說明散熱器散熱性能越好經(jīng)濟(jì)方面的要求，散熱器傳給房間的單位熱量所需要金屬耗量越少成本越低，其經(jīng)濟(jì)性越好。安裝使用和工藝方面要求，散熱器應(yīng)具有一定機(jī)械強(qiáng)度和承壓能力，散熱器的結(jié)構(gòu)形式應(yīng)便于組合成所需要的散熱面積，結(jié)構(gòu)尺寸要小，少占房間面積和空間。衛(wèi)生和美觀方面要求：散熱器外表光滑，不積灰易于清洗，散熱器裝設(shè)應(yīng)影響房間美觀。4.3對(duì)散熱器的注意事項(xiàng)1、具有腐蝕性氣體的工業(yè)建筑或相對(duì)濕度較大的房間，應(yīng)采用耐腐蝕的散熱器。2、采用鋼制散熱器時(shí)，必須注意防腐問題。應(yīng)采用閉式系統(tǒng)，并滿足產(chǎn)品對(duì)水質(zhì)的要求，在非采暖季節(jié)采暖系統(tǒng)應(yīng)充水保養(yǎng)。3、鋁制散熱器的腐蝕問題日益突出，造成的腐蝕主要是堿腐蝕，采用鋁制散熱器時(shí)，應(yīng)選用內(nèi)防腐性鋁制散熱器，并滿足產(chǎn)品對(duì)水質(zhì)的要求。注：本系統(tǒng)選用的是GBG/D-570型散熱器4.4散熱器常見故障的排除1、散熱器主體局部不熱：主要集中在下進(jìn)下出的安裝方式上，原因?yàn)樯崞鲀?nèi)部有氣體不能排出。解決方式為將排氣閥開啟，將散熱器內(nèi)部氣體排出?；驒z查系統(tǒng)是否壓差過小或流量過低。2、散熱器整體不熱：下進(jìn)下出的安裝方式，檢查散熱器安裝時(shí)是否將導(dǎo)流閥上下位置安裝顛倒；上進(jìn)下出的安裝方式，檢查散熱器安裝時(shí)是否未將流閥開啟?；蛘呤窍到y(tǒng)否存在問題。4.5散熱器的選取本設(shè)計(jì)選用GBG/D-570鋼制扁管型散熱器，柱型散熱器是單片的柱狀連通體，每片各有幾個(gè)中空的立柱相互連通，可根據(jù)散熱面積的需要，把各個(gè)單片組對(duì)成一組。該散熱器傳熱系數(shù)高，每片散熱面積少，易組成所需散熱面積。鋼制高頻焊翅片管散熱器是近年類使用頻率比較高的新型散熱器，體積小，散熱量大。表4.1GBG/D-570鋼制圓柱散熱器數(shù)據(jù)表型號(hào)單片尺寸計(jì)算公式散熱量ΔT=64.5℃進(jìn)出口中心距mm高度mm長度mm寬度mmGBG/D-570570624455010464.6散熱器的計(jì)算（4.1）備注說明本設(shè)計(jì)采用鋼制扁管型散熱器，由路咬慶主編的《實(shí)用供熱空調(diào)設(shè)計(jì)手冊》表4.1的數(shù)據(jù)就課查到，單個(gè)散熱片的散熱量公式也可得到；?t由于本設(shè)計(jì)是鋼制扁管形且長度小于600mm，所以β1=0.95散熱器支管的連接方式不同，散熱器內(nèi)部的水流趨勢、分配以及外表面溫度分布的不同，使傳熱量發(fā)生變化，用支管連接方式修正系數(shù)β2來進(jìn)行修正，本設(shè)計(jì)采用的是下供下回也就是下進(jìn)下出的連接方式，所以β安裝形式修正系數(shù)β3的確定：裝在墻的凹槽內(nèi)（半暗裝）散熱器上部距離為100mm,取1.06；明裝但在散熱器上部有窗臺(tái)板覆蓋，散熱器距窗臺(tái)板高度為150mm,取1.02；裝在罩內(nèi),上部敞開，下部距地150mm,取0.95；裝在罩內(nèi),上部下部開口，開口高度均為150mm,取1.04。本設(shè)計(jì)β3=1.04.n=Ff（4.舉例說明：（以101房間為例）已知條件：（1）101房間熱負(fù)荷Q為1281.28W；f=4.531(?t)?t=ti+t02?tβ1=0.95，β2=1.251，β列式計(jì)算；Q=1281.28Wf=4.531(?t)1.3061=4.531×（95+70/2-18）1.3061F=Qn=Ff散熱器數(shù)據(jù)層數(shù)房間號(hào)熱負(fù)荷QW溫度t℃片數(shù)修正系數(shù)β連接方式修正系數(shù)β安裝形式修正系數(shù)β片數(shù)n/片片數(shù)取整/片一層1011281.28180.921.0091.041..1521021840.66180.921.0091.041.662103889.87180.921.0091.040.8111041297.99180.921.0091.041.172105889.87180.921.0091.040.8111061297.99180.921.0091.041.172107889.87180.921.0091.040.8111081297.99180.921.0091.041.172109889.87180.921.0091.040.8111101297.99180.921.0091.041.1721111281.28180.921.0091.041.1521121840.66180.921.0091.041.662一層總計(jì)20片二層2011102.7180.921.0091.040.9912021689.42180.921.0091.041.522203711.29180.921.0091.040.6412041116.75180.921.0091.041.012205711.29180.921.0091.040.6412061116.75180.921.0091.041.012207711.29180.921.0091.040.6412081116.75180.921.0091.041.012209711.29180.921.0091.040.6412101116.75180.921.0091.041.0122111102.7180.921.0091.040.9912121689.42180.921.0091.041.522二層總計(jì)18片三層3011281.28180.921.0091.041..1523021840.66180.921.0091.041.662303889.87180.921.0091.040.8113041297.99180.921.0091.041.172305889.87180.921.0091.040.8113061297.99180.921.0091.041.172307889.87180.921.0091.040.8113081297.99180.921.0091.041.172309889.87180.921.0091.040.8113101297.99180.921.0091.041.1723111281.28180.921.0091.041.1523121840.66180.921.0091.041.662三層20片

5水力計(jì)算5.1遵循的基本原則供熱管網(wǎng)干管的管徑不應(yīng)小于50mm,通往各單體建筑物的分支管管徑一般不宜小于32mm.在供熱管網(wǎng)設(shè)計(jì)中，有的點(diǎn)出現(xiàn)靜壓值超過允許值時(shí)，應(yīng)分開設(shè)置孤獨(dú)的供熱系統(tǒng)。5.2供暖系統(tǒng)管路水力計(jì)算的主要任務(wù)按已知系統(tǒng)各管段的流量和系統(tǒng)的循環(huán)作用壓力確定個(gè)管段管徑；按已知系統(tǒng)各管段的流量和各管段的管徑確定系統(tǒng)所必需的循環(huán)作用壓力；按已知系統(tǒng)各管段的管徑和該管段的允許降壓確定通過該管道的水流量；5.3水力計(jì)算步驟統(tǒng)計(jì)出立管承擔(dān)的負(fù)荷，查25℃溫差的熱水供暖系統(tǒng)水力計(jì)算表，該負(fù)荷對(duì)應(yīng)的各種管徑，找到比摩阻〈120Pa的那個(gè)就行，這是立管管徑。單側(cè)接散熱器的支管管徑等于立管管徑，雙側(cè)接散熱器的支管管徑的確定方法同立管。有了立管、支管管徑后，查垂直單管同程式管壓降2KPa時(shí)的流量表，得各立管的查表流量。選擇等壓降法計(jì)算按25℃供水溫差計(jì)算，把各立管的壓降視作相等，計(jì)算順序：先立管，后干管。立管由遠(yuǎn)及近，干管無所謂，但要求兩個(gè)立管之間的干管壓損誤差盡量小于10%。實(shí)在做不到，交給閥門。5.4水力計(jì)算公式沿程阻力：
