For balances the electrical work load, to unify the valley peak electrovalence policy which Changsha implements, gathered the airconditioning system with ice storage and the conventional airconditioning system efficiency to the ice carries on the analysis parison thus to determine this construction suited using the air conditioning systems with ice system. Through to this building cold load calculation and cold load distributed situation analysis, thus had determined the ice storage the movement strategy which the airconditioning system with ice storage suitably used, the working pattern and the operating control plan then had determined its unit capacity and ice storage capacity. This air conditioning systems with ice storage is uses of the air blower plate tube adds the new atmosphere system, new atmosphere system is not responsible for in the room to shoulder the outdoor air processes to the room in some to enthalpy condition sends in the room. Finally, airconditioning system with ice storage when the discussion ice the efficiency airconditioning system with ice the energy consumption situation and the efficiency has carried on the whole analysis and the parison. Key words: airconditioning system, ice storage, economic analysis, building of office 共 3 頁 第 1 頁 ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ 裝 ┊ ┊ ┊ ┊ ┊ 訂 ┊ ┊ ┊ ┊ ┊ 線 ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ 目 錄 1 緒 論 ...............................................................1 冰蓄冷空調(diào)技術(shù)的社會(huì)背景 .........................................1 冰蓄冷空調(diào)的發(fā)展歷史和現(xiàn)狀 .......................................1 冰蓄冷空調(diào)系統(tǒng)介紹 ...............................................2 冰蓄冷空調(diào)的基本概念 .........................................2 冰蓄冷系統(tǒng)的分類 .............................................4 冰蓄冷系統(tǒng)的運(yùn)行方式 .........................................4 冰蓄冷系統(tǒng)的工作模式 .........................................5 低溫送風(fēng)空調(diào) .................................................8 冰蓄冷在制冷空調(diào)中的發(fā)展趨勢 .....................................9 建立與冰蓄冷相結(jié)合的低溫送風(fēng)空調(diào)系統(tǒng) .........................9 開發(fā)新型的蓄冷技術(shù)和設(shè)備 .....................................9 建立區(qū)域性蓄冷空調(diào)供冷站 .....................................9 應(yīng)用蓄冷空調(diào)技術(shù)的意義 ..........................................10 2 建筑概況 ...........................................................12 項(xiàng)目名稱 ........................................................12 設(shè)計(jì)依據(jù) ........................................................12 工程概況 ........................................................12 建筑物概況 ..................................................12 建筑的圍護(hù)結(jié)構(gòu)的情況 ........................................13 室內(nèi)外設(shè)計(jì)參數(shù)的確定 ............................................14 室外空氣計(jì)算參數(shù) ............................................14 室內(nèi)空氣設(shè)計(jì)標(biāo)準(zhǔn) ............................................15 3 設(shè)計(jì)方案論證 ......................................................16 夏季設(shè)計(jì)日空調(diào) 冷負(fù)荷 ............................................16 蓄冷系統(tǒng)的運(yùn)行策略和工作模式以及工作流程 ........................17 蓄冷系統(tǒng)運(yùn)行策略 ............................................17 冰蓄 冷空調(diào)設(shè)計(jì)模式的選定 ....................................17 冰蓄冷空調(diào)系統(tǒng)的流程配置 ....................................17 設(shè)備的確定 ......................................................18 制冷機(jī)組的確 定 ..............................................18 蓄冷設(shè)備容量確定 ............................................18 機(jī)組運(yùn)行情況的確定 .............................................19 蓄冷介質(zhì)與蓄冷系統(tǒng)形式選擇 ......................................20 蓄冷介質(zhì)的選取 ..............................................20 蓄冷形式的選取 ..............................................20 設(shè)備的選擇： ....................................................21 冷源設(shè)備的選擇 ..............................................21 蓄冰設(shè)備的選擇 ..............................................21 共 3 頁 第 2 頁 ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ 裝 ┊ ┊ ┊ ┊ ┊ 訂 ┊ ┊ ┊ ┊ ┊ 線 ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ 其他設(shè)備的選擇計(jì)算 ..........................................22 方案的比較及經(jīng)濟(jì)分析與結(jié)論 ......................................22 方案一：螺桿水冷式冷水機(jī)組 ..................................23 方案二：螺桿水冷式雙工況冷水機(jī)組 +蓄冰設(shè)備 ...................24 方案三：風(fēng)冷式螺桿冷水機(jī)組 +蓄冰設(shè)備 .........................25 方案比較（采用價(jià)值分析法） ..................................25 冰蓄冷系統(tǒng)的回收年限 ........................................27 結(jié)論和建議 ..................................................28 4 冷負(fù)荷的計(jì)算 ................
