畢業(yè)設(shè)計(jì)：平谷新城某高層住宅樓室內(nèi)給排水、消防與采暖系統(tǒng)設(shè)計(jì)

.2系統(tǒng)方案的確定5.2.1采暖熱源的選擇由于鍋爐房燃煤造成污染比較嚴(yán)重，近年來已受到國家限制使用，所以采暖熱源采用城市供熱管網(wǎng)，供、回水溫度95℃/70℃，外網(wǎng)埋深1.2m。5.2.2采暖系統(tǒng)的選擇室內(nèi)供暖方案選擇設(shè)計(jì)是室內(nèi)供暖設(shè)計(jì)的重要環(huán)節(jié)，它不僅直接影響系統(tǒng)的運(yùn)行效果，而且也直接影響供暖工程的造價(jià)。不同的系統(tǒng)方案根據(jù)不同的建筑形式與特點(diǎn)進(jìn)行選擇，本建筑為一高層住宅樓，適合采用集中供熱，分戶計(jì)量的形式。本設(shè)計(jì)采暖系統(tǒng)采用水平雙管異程式、同側(cè)下供下回式分戶計(jì)量系統(tǒng)。分戶計(jì)量的主要目的：（1）提高、激勵(lì)節(jié)能意識，促進(jìn)行為節(jié)能，達(dá)到節(jié)能效果；（2）因供暖的特殊性，造成供暖的均攤性。不像水、電和氣一樣能精確計(jì)量其用量，收費(fèi)具有合理性；（3）確保供暖費(fèi)的均攤，更加公平、合理；（4）滿足個(gè)性化要求，可合理設(shè)定或保持室內(nèi)熱環(huán)境水平，更節(jié)能環(huán)保；（5）在供熱數(shù)量和質(zhì)量方面，有效的提供了對供熱部門實(shí)現(xiàn)有效監(jiān)督的可能性。5.2.3管道安裝原則共用立管供、回水干管和共用立管宜采用熱鍍鋅鋼管；共用立管水平分環(huán)系統(tǒng)所供層數(shù)一般不超16層超過一定層數(shù)的時(shí)候應(yīng)該進(jìn)行豎向分區(qū)。本設(shè)計(jì)共15層，可不進(jìn)行豎向分區(qū)；共用立管設(shè)置在管道井內(nèi)。供、回水立管在管道井中與共用立管相連，各分戶系統(tǒng)的入口裝置應(yīng)安裝在管道井內(nèi)，并具備檢修的條件；一般一對共用立管所負(fù)擔(dān)的戶內(nèi)系統(tǒng)數(shù)不應(yīng)大于三戶。本設(shè)計(jì)每對立管恰好連接三戶。戶內(nèi)管道（1）戶內(nèi)的供暖管道安裝時(shí)，最好采用熱鍍鋅鋼管螺紋連接或者塑料管材，暗裝時(shí)最好采用塑料管材或者有色金屬管材；（2）戶內(nèi)地面管道可暗裝在本層地面以下溝槽或墊層內(nèi)。5.3散熱器的選擇與計(jì)算5.3.1散熱器的選擇選用散熱器類型時(shí)，應(yīng)注意如下基本要求：（1）熱工要求：應(yīng)盡量提高散熱器傳熱系數(shù)；（2）經(jīng)濟(jì)方面的要求：散熱器散發(fā)到房間單位熱量所耗金屬量越少，成本越低，經(jīng)濟(jì)性越好；（3）安裝、使用和工藝方面的基本要求：散熱器應(yīng)具有足夠的機(jī)械強(qiáng)度和承壓能力，尺寸應(yīng)盡可能小，節(jié)省空間；（4）美觀和衛(wèi)生方面的要求：散熱器要外表面光滑，不積灰且易于清掃；（5）使用壽命要求：散熱器應(yīng)不易被腐蝕破壞。目前的散熱器種類繁多，可從容的選擇，要用其所長，避其所短，根據(jù)情況有所側(cè)重。本設(shè)計(jì)選用M-132型鑄鐵散熱器。表5.6M-132型鑄鐵散熱器參數(shù)型號散熱面積（㎡/片）工作壓力（MPa）傳熱系數(shù)計(jì)算公式（W/（㎡·℃））M-1320.240.5K=2.426Δt0.2865.3.2散熱器的計(jì)算（1）散熱器面積的計(jì)算計(jì)算公式：（5-7）式中Q—散熱器的散熱量，W；—散熱器內(nèi)熱媒平均溫度，℃；—供暖室內(nèi)計(jì)算溫度，℃；—散熱器傳熱系數(shù)，W/（m2·℃）；—散熱器組裝片數(shù)修正系數(shù)；—散熱器連接形式修正系數(shù)；—散熱器安裝形式修正系數(shù)。（2）散熱器內(nèi)熱媒平均溫度計(jì)算公式：（5-8）式中—散熱器進(jìn)水溫度，℃；—散熱器回水溫度，℃。城市供熱外網(wǎng)的供回水溫度：95℃/70℃，即=95℃，=70℃，所以=(95+70)/2=82.5℃（3）散熱器傳熱系數(shù)室內(nèi)設(shè)計(jì)溫度：=18℃，=10℃平均溫差：=tpg-tn1=82.5-18=64.5℃，=tpg-tn2=82.5-10=72.5℃所以在平均溫差下的傳熱系數(shù)：散熱器修正系數(shù)散熱器組裝片數(shù)修正系數(shù)，先假定=1.0；表5.7散熱器組裝片數(shù)修正系數(shù)每組片數(shù)＜66-1011-20＞200.951.001.051.10散熱器的連接形式修正系數(shù)，對于M-132型散熱器，連接形式同側(cè)上進(jìn)下出，=1.0；散熱器的安裝形式修正系數(shù)，散熱器明裝，=1.0。所以（5）散熱器片數(shù)實(shí)際采用片數(shù)n為：（5-9）式中—每片散熱器散熱面積，㎡/片。然后n取整為N片。（6）由以上計(jì)算方法，算出西部（東部同樣）各采暖房間所需散熱器片數(shù)如下表。表5.8西部各采暖房間所需散熱器片數(shù)計(jì)算表散熱器計(jì)算房間編號QΔtKβF’N’β1FnN1層各采暖房間的散熱器計(jì)算臥室1152882.51864.57.9912.9612.31.053.1113.013臥室2122582.51864.57.9912.389.91.002.389.910起居室1127082.51864.57.9912.4610.31.052.5910.811衛(wèi)生間148082.51864.57.9910.933.90.950.883.74廚房133482.51072.58.2610.562.30.950.532.22衣帽間176482.51864.57.9911.486.21.001.486.26起居室2208282.51864.57.9914.0416.81.054.2417.718書房68082.51864.57.9911.325.50.951.255.25臥室365982.51864.57.9911.285.30.951.215.15臥室4122582.51864.57.9912.389.91.002.389.910起居室3143282.51864.57.9912.7811.61.052.9212.212衛(wèi)生間322982.51864.57.9910.441.80.950.421.82廚房348182.51072.58.2610.803.30.950.763.23衣帽間265982.51864.57.9911.285.30.951.215.152-14層各采暖房間的散熱器計(jì)算臥室1129982.51864.57.9912.5210.51.052.6511.011臥室2109182.51864.57.9912.128.81.002.128.89起居室195182.51864.57.9911.847.71.001.847.78衛(wèi)生間133282.51864.57.9910.642.70.950.612.53廚房129382.51072.58.2610.492.00.950.461.92衣帽間169482.51864.57.9911.355.60.951.285.35臥室396282.51864.57.9911.877.81.001.877.88臥室446182.51864.57.9910.903.70.950.853.54起居室291082.51864.57.9911.777.41.001.777.48臥室547382.51864.57.9910.923.80.950.873.64臥室6109182.51864.57.9912.128.81.002.128.89起居室3111082.51864.57.9912.159.01.002.159.09衛(wèi)生間318882.51864.57.9910.371.50.950.351.42廚房343182.51072.58.2610.723.00.950.682.83衣帽間259482.51864.57.9911.154.80.951.104.6515層（頂層）各采暖房間的散熱器計(jì)算臥室1148482.51864.57.9912.8812.01.053.0212.613臥室2121782.51864.57.9912.369.81.002.369.810起居室1126482.51864.57.9912.4510.21.052.5810.711衛(wèi)生間139382.51864.57.9910.763.20.950.733.03廚房133282.51072.58.2610.562.30.950.532.22衣帽間174982.51864.57.9911.456.11.001.456.16臥室3107682.51864.57.9912.098.71.002.098.79臥室454582.51864.57.9911.064.40.951.004.24起居室2110782.51864.57.9912.159.01.002.159.09臥室565782.51864.57.9911.285.30.951.215.05臥室6121782.51864.57.9912.369.81.002.369.810起居室3144182.51864.57.9912.8011.71.052.9412.212衛(wèi)生間325082.51864.57.9910.482.00.950.461.92廚房347382.51072.58.2610.793.30.950.753.13衣帽間265082.51864.57.9911.265.30.951.205.055.3.3散熱器的布置在布置散熱器時(shí)，應(yīng)注意以下原則：一般散熱器應(yīng)安裝在外墻窗臺(tái)下；為了防止凍裂散熱器，在兩道門之間，禁止設(shè)置散熱器；散熱器一般應(yīng)明裝，內(nèi)部裝修要求高的民用建筑可采用暗裝；公共建筑樓梯間的散熱器，應(yīng)分配在底層或按比例分配在下部各層，對于住宅樓梯間一般可不設(shè)散熱器。5.4水力計(jì)算5.4.1水力計(jì)算方法1.流量已知熱負(fù)荷和供回水溫差求管段流量計(jì)算公式：（5-10）式中—管段流量，kg/h；—管段熱負(fù)荷，W；—供回水溫差，℃。2.管徑根據(jù)已得出的流量在一定流速范圍內(nèi)，選擇最不利環(huán)路各管段管徑。當(dāng)系統(tǒng)壓損有限制時(shí)，應(yīng)先求出單位長度摩擦阻力損失，然后在選取管徑。計(jì)算公式：（5-11）式中—平均單位長度摩擦損失，Pa/m；—摩擦損失占總壓損的百分?jǐn)?shù)，熱水系統(tǒng)取0.5；—系統(tǒng)允許總壓損，Pa；—最不利環(huán)路總長度，m。壓力損失根據(jù)已知流量和管徑，計(jì)算各管段壓力損失。計(jì)算公式：（5-12）式中—計(jì)算管段壓力損失，Pa；—計(jì)算管段沿程損失，Pa；—計(jì)算管段局部損失，Pa；—每米管長沿程損失，Pa/m；—管段長度，m。（5-13）式中—管段摩擦阻力系數(shù)；—管內(nèi)徑，m；—管道內(nèi)熱媒流速，m/s；—熱媒密度，kg/m3。（5-14）式中—管段總局部阻力系數(shù)。4.環(huán)路壓力平衡根據(jù)算出的各管段壓力損失，進(jìn)行并聯(lián)環(huán)路壓力平衡
