1、長(zhǎng)春工程學(xué)院畢業(yè)設(shè)計(jì)(論文)蘭州市黃河5號(hào)樓采暖及換熱站設(shè)計(jì)HeatingheattransferstationdesignoftheYellowRiverBuildingNo.5，Lanzhou摘要隨著我國(guó)城市建設(shè)事業(yè)的發(fā)展，以及國(guó)家對(duì)于能源與環(huán)境保護(hù)的要求，供暖系統(tǒng)的規(guī)模從單幢采暖系統(tǒng)發(fā)展成為中大型區(qū)域集中供暖系統(tǒng)，出現(xiàn)了大量住宅，公共建筑的集中供暖系統(tǒng)。集中供暖在節(jié)能和壞境保護(hù)方面都有很大的優(yōu)勢(shì)，發(fā)展速度很快。本設(shè)計(jì)為蘭州市市一棟

2、辦公樓的供熱及換熱站設(shè)計(jì)。采暖部分為二十二層，高84米。設(shè)計(jì)用城市熱力管網(wǎng)提供的95℃熱水為熱源，定壓水泵定壓。根據(jù)辦公樓的結(jié)構(gòu)、各房間用途及經(jīng)濟(jì)性和技術(shù)可行性比較，采用了豎向分三區(qū)，各區(qū)又分兩個(gè)環(huán)路，采用雙管順流下供下回同程式熱水采暖系統(tǒng)。通過圍護(hù)結(jié)構(gòu)的傳熱系數(shù)計(jì)算、各采暖房間熱負(fù)荷計(jì)算、房間散熱器的選擇與計(jì)算、系統(tǒng)管路的水力計(jì)算，同時(shí)還考慮了安全可靠、經(jīng)濟(jì)合理、節(jié)能等方面的要求，使該建筑較好的滿足了采暖要求。換熱站的設(shè)計(jì)主要包括設(shè)備

3、的布置，定位尺寸確定，換熱器的計(jì)算選型，循環(huán)水泵和補(bǔ)水泵的計(jì)算選型以及輔助設(shè)備的選擇計(jì)算。關(guān)鍵詞關(guān)鍵詞：集中供熱，熱負(fù)荷，水力計(jì)算換熱器長(zhǎng)春工程學(xué)院畢業(yè)設(shè)計(jì)(論文)AbstractWiththedevelopmentofcityconstructioninourcountrynationalrequirementsfenergyenvironmentalprotectionheatingsystemscalefromasinglebui
