1、北京市某低溫?zé)崴匕遢椛洳膳こ淘O(shè)計BeijingLowtemperaturehotwaterfloorradiantEngineeringDesign屆系專業(yè)學(xué)號學(xué)生姓名指導(dǎo)教師完成日期摘要本設(shè)計主要是對北京市某住在樓進行低溫?zé)崴匕遢椛洳膳南到y(tǒng)設(shè)計。該建筑物共二十層，建筑面積為9607m2，建筑總高60m，層高3m，由于建筑高度高于50m，對建筑在垂直方向上分為高低兩個區(qū)。設(shè)計主要任務(wù)對低溫?zé)崴匕遢椛洳膳瘒鴥?nèi)外現(xiàn)狀，總負(fù)荷為472kW，由于地板輻射采暖室內(nèi)實感溫度高于設(shè)計溫度，所以計算時將所得結(jié)果取
2、95%，以滿足節(jié)能要求。在管道鋪設(shè)方面，選擇了交聚乙烯管道雙回形鋪設(shè)方式，在各戶安裝溫控閥和熱計量表，對各用戶進行溫度控制熱盒分戶計量。對管網(wǎng)進行水力計算確定管徑，根據(jù)供熱管網(wǎng)的水力計算結(jié)果選擇用戶系統(tǒng)與供熱管網(wǎng)的連接方式及用戶入口裝置，確定換熱站的熱力計算和設(shè)備選型等。本設(shè)計所用外網(wǎng)熱力熱水，外網(wǎng)所提供95/75℃熱水。在住宅樓的東面建一所換熱站，換熱后供回水溫度40/30℃，換熱站設(shè)備包括換熱器、循環(huán)水泵、補水泵、除污器等，采暖補水為軟化水，定壓采用補水泵變頻定壓形式，采暖水溫要求自動控制。換熱站內(nèi)設(shè)備
