【正文】 1 圖紙及計(jì)算書 153893706 上海市某商務(wù)大廈空調(diào)、通風(fēng)設(shè)計(jì) 摘要： 商務(wù)大廈集辦公、會(huì)議、餐飲于一體，屬商務(wù)性質(zhì)?？照{(diào)系統(tǒng)主要采用風(fēng)機(jī)盤管加獨(dú)立的新風(fēng)系統(tǒng)，廚房、走道只送新風(fēng)，新風(fēng)處理到室內(nèi)等焓線，過渡季節(jié)只供新風(fēng)。配電房均 采用分體式空調(diào)器。綜合初投資、運(yùn)行、管理費(fèi)用考慮，冷熱源選用大型單螺桿風(fēng)冷熱泵機(jī)組。為滿足空氣品質(zhì)要求，整幢大廈的房間均設(shè)計(jì)了通風(fēng)系統(tǒng)。地下室采用了機(jī)械送排風(fēng)加誘導(dǎo)器系統(tǒng)；廚房采用全面送排風(fēng)與局部排風(fēng)相結(jié)合；電梯前室及樓梯間設(shè)計(jì)了正壓送風(fēng)系統(tǒng)。 關(guān)鍵詞： 風(fēng)冷熱泵 空氣品質(zhì) 誘導(dǎo)器系統(tǒng) 正壓送風(fēng) Summary: The business mansion gathers to transact, meeting, dining in integral whole, belong to the business property. The air condition system main adoption breeze machine dish tube adds the independent new breeze system, the kitchen, aisle sends the new breeze only, the new breeze handles indoor etc. enthalpy line, transition of the season to send the new breeze only. Go together with to give or get an electric shock the building to all adopt the body type air condition machine of the cent. Comprehensive beginning investment, circulate, administrative expense consider, the cold and hot source chooses with the large and single screw breeze cold hot pump machine set. In order to satisfy the air quality request, the whole room of mansion all designed the well ventilated system. The ground floor adopts the machine to send to 2 line up the breeze to add to induce the machine system。 The kitchen adoption sends to line up the breeze and parts to line up the breeze to bine together pletely。 The elevator ex room and stair well designed just press to send the breeze system. Keywords: Cold hot pump of breeze Air quality Induce the machine system Just press to send the breeze 目 錄 1 工程概況 .............................................................1 2 設(shè)計(jì)依據(jù) .............................................................1 設(shè)計(jì)任務(wù)書 .................................................1 設(shè)計(jì)規(guī)范及標(biāo)準(zhǔn) .............................................1 基本氣象參數(shù) ...............................................1 ........................................................1 ........................................................1 室內(nèi)設(shè)計(jì)參數(shù) ...............................................1 設(shè)計(jì)原則 ...................................................2 ........................................................2 ........................................................2 3 負(fù)荷計(jì)算 ..............................................2 冷負(fù)荷計(jì)算 .................................................2 通過圍護(hù)結(jié)構(gòu)傳入的熱量計(jì)算 ......................................3 過玻璃窗的日射得熱引起的冷負(fù)荷 ..................................3 人員散熱引起的冷負(fù)荷 ....................................................4 照明散熱引起的冷負(fù)荷 ...................................................4 設(shè)備散熱冷負(fù)荷 ..................................................4 食物散熱冷負(fù)荷 ..................................................4 新風(fēng)冷負(fù)荷 ......................................................4 熱負(fù)荷計(jì)算 .................................................4 圍護(hù)結(jié)構(gòu)得基本耗熱量引起得熱負(fù)荷 ................................4 修正基本耗熱量 ..................................................5 濕負(fù)荷計(jì)算 .................................................5 人體散濕量 ......................................................5 食物散濕量 ......................................................6 新風(fēng)濕負(fù)荷 ......................................................6 負(fù)荷計(jì)算結(jié)果列表 ...........................................6 4 空調(diào)機(jī)組選型 ..........................................8 3 風(fēng)機(jī)盤管選型計(jì)算 ...........................................8 房間氣流組織設(shè)計(jì) ...........................................9 新風(fēng)機(jī)組選型及管徑的確定 ...................................10 新風(fēng)機(jī)組選型 ....................................................10 風(fēng)管加濕器的選擇 ................................................11 風(fēng)管管徑的確定計(jì)算 ..............................................12 最不利管路的壓力損失 ............................................15 分體式空調(diào)器選型 ...........................................16 5 水系統(tǒng)設(shè)計(jì) ............................................16 水系統(tǒng)方案的確定 ...........................................16 管路的布置和管徑的確定 .....................................16 凝結(jié)水設(shè)計(jì) ......................................................16 冷凍水設(shè)計(jì) ......................................................17 水環(huán)路阻力損失的計(jì)算 .......................................20 水環(huán)路水力平衡計(jì)算 .........................................20 6 冷、熱源系統(tǒng)的確定及選型 .............................21 方案確定及可行性 ...........................................21 系統(tǒng)方案 ........................................................21 方案的可行性 ....................................................21 熱泵的選型 .................................................21 選型方法 ........................................................21 選型結(jié)果 ........................................................22 7 冷凍水泵選型 ..........................................22 計(jì)算及選型 .................................................22 水泵配管 ...................................................23 8 電子除垢儀選型 ........................................23 9 膨脹水箱的選型 ........................................23 膨脹水量的計(jì)算 .............................................23 系統(tǒng)補(bǔ)給水量的計(jì)算 .........................................24 膨脹水箱的選型 .............................................24 10 水系統(tǒng)的泄水及排氣 ...................................25 泄水設(shè)計(jì) .................................................25 排氣設(shè)計(jì) ..................................................25 11 管道的保溫及防腐設(shè)計(jì) .................................25 風(fēng)管的保溫及防腐 ..........................................25 保溫目的 ........................................................25 保溫材料的選擇 ..................................................25 4 ................................................25 水管的保溫及防腐 ..........................................26 保溫及防腐目的 ..................................................26 保溫材料的選擇 ..................................................26 12 通風(fēng)設(shè)計(jì) .............................................26 地下車庫通風(fēng)設(shè)計(jì) ..........................................26 通風(fēng)方案的確定 .................................................26 通風(fēng)量的計(jì)算 ..................
