The first thing is to ensure the basic data of the design and carry on the heat load calculation. Then it selects the design of heating system according to the heat load and type of building. Finally, it confirms to adopt mechanical cycle with program single pipe hot water heating system. Stand pipe locates in the 110 111 of building to top which is divided into two loop which slope , and is equipped with collected the gas pitcher vertically in each return circuit highest point, the return pipe lies in underground 0. 5m, the system adopts expand water tank pigeonhole to carry； It lies in front of the entry to the circulation pump. Radiators adopt813 type, obviously outfit, and are apart from the window board , indoor heating pipeline obviously outfit. pipe and radiator are connected with the same side connection which are from the top to the below. It does not consider the heat which pipeline dispels to the room. Draw pipeline systematic picture, and make the label, it calculates water conservancy ,then make the return water temperature calculation for each layer and make sure each room number of radiator, and the layout. The design blueprint includes crest layer、 standard layer and the first floor39。s heating plane chart and heating system diagram. Though this design the indoor temperature gets the improvement , arrives 哈爾濱理工大學(xué)學(xué)士學(xué)位論文 III design requirements and adopts hot water heating is much better than steam heating in hygiene term、 consume the energy and economic performance. Keywords heating。 heat load。 hydraulic calculation 哈爾濱理工大學(xué)學(xué)士學(xué)位論文 IV 目 錄 摘要 .....................................................................................................................Ⅰ Abstract ...............................................................................................................Ⅱ 第 1 章 緒論 .................................................................................................... 1 背景 ....................................................................................................... 1 設(shè)計(jì)內(nèi)容 ............................................................................................... 2 第 2 章 原始資料 ............................................................................................ 3 工程概況 ............................................................................................... 3 設(shè)計(jì)參數(shù) ............................................................................................... 3 本章小結(jié) ............................................................................................... 3 第 3 章 建筑物供暖系統(tǒng)熱負(fù)荷的計(jì)算 ........................................................ 4 供暖系統(tǒng)熱負(fù)荷 ................................................................................... 4 圍護(hù)結(jié)構(gòu)耗熱量 ................................................................................... 5 基本耗熱量 .................................................................................... 5 圍護(hù)結(jié)構(gòu)的附加（修正）耗熱量 ................................................ 5 冷風(fēng)滲透耗熱量 ................................................................................... 7 冷風(fēng)侵人耗熱量 ................................................................................... 7 熱負(fù)荷計(jì)算實(shí)例 ................................................................................... 7 計(jì)算資料 ........................................................................................ 7 圍護(hù)欄結(jié)構(gòu)傳熱耗熱量的計(jì)算 .................................................... 9 冷風(fēng)滲透耗熱量的計(jì)算 ................................................................ 9 冷風(fēng)滲透耗熱量的計(jì)算 ................................................................ 9 本章總結(jié) ............................................................................................. 11 第 4 章 方案的選擇 ...................................................................................... 13 熱媒的選擇 ......................................................................................... 13 熱水熱媒和蒸氣熱媒的比較 ...................................................... 13 選擇熱水熱媒 .............................................................................. 13 熱水供暖系統(tǒng)的選擇 ......................................................................... 13 機(jī)械循環(huán)熱水供暖系統(tǒng)與重力循環(huán)熱水供暖系統(tǒng)的區(qū)別 ...... 13 單管系統(tǒng)與雙管系統(tǒng)區(qū)別 .......................................................... 14 異程式系統(tǒng)與同程式系統(tǒng) .......................................................... 14 本章小結(jié) ............................................................................................. 15 第 5 章 室內(nèi)熱水供暖系統(tǒng)的管路布置及水機(jī)計(jì)算 .................................. 16 本系統(tǒng)管路的布置考慮了一下幾點(diǎn) ................................................. 16 設(shè)計(jì)注意事項(xiàng) ..................................................................................... 17 該 建筑采暖供熱系統(tǒng)的布置 ............................................................. 18 哈爾濱理工大學(xué)學(xué)士學(xué)位論文 V 水力計(jì)算 ....................
