The Overall height is meters, covers an area of 10172 square meters. This article first estimates the load , choosing chiller and a water boiler as cold and heat source. For every room of different functions,such as Cafeteria, Conference roomand so on covering a large space chooses entire air can get air of better quality and can run in the tansition seasons with all fresh air , which can make best use of natural energy and save energy. For offices and some other small rooms which use more flexibly, chose fancoil system that can achieve a more flexible control. In the second parts ,the author first do a accurate calculation of the load and then amend the parameters of the units. For the all air system ， the air is cooled to machine dew point. For fan coil system the fresh air is forced into the room independently after being cooled. Then the author definit the state of the air by adifferent room from the air supply using different methods, such as Cafeteria and Conference room use the casual giftflowway, the room air supply by the way side. In this paper, airconditioning systems, vibration and noise reduction insulation also do a certain amount of discussion. the paper used the mechanical ventilation, exhaust pipe and the exhaust pipe shared by electric exhaust valve and exhaust the state switch. Key words: airconditioning all air system air water fancoil system mechanical ventilation system 目錄 4 目錄 摘要 ................................................................................................................................. 2 Abstract........................................................................................................................... 3 第一章 工程概況 ............................................................................................................. 6 建筑概況 ............................................................................................................. 6 設(shè)計(jì)參數(shù) ............................................................................................................. 6 長(zhǎng)沙市室外設(shè)計(jì)參數(shù) .................................................................................. 6 長(zhǎng)沙市室內(nèi)設(shè)計(jì)參數(shù) .................................................................................. 6 第二章 負(fù)荷計(jì)算 ............................................................................................................. 7 建筑圍護(hù)結(jié)構(gòu)冷負(fù)荷計(jì)算 ..................................................................................... 7 建筑圍護(hù)結(jié)構(gòu)的選擇 .................................................................................. 7 通過墻體引起的冷負(fù)荷計(jì)算 ........................................................................ 7 通過外窗引起的冷負(fù)荷計(jì)算 ........................................................................ 8 人體散熱和照明得熱形成的冷負(fù)荷計(jì)算 .............................................................. 10 ................................................................................ 10 照明冷負(fù)荷負(fù)荷： .................................................................................... 10 各個(gè)房間冷負(fù)荷匯總 ...........................................................................................11 房間濕負(fù)荷計(jì)算 ..................................................................................................11 房間熱負(fù)荷 ........................................................................................................ 12 第三章 空調(diào)系統(tǒng)方案的確定 .......................................................................................... 13 空調(diào)系統(tǒng)設(shè)計(jì)的基本原則 ................................................................................... 13 空調(diào)系統(tǒng)方案的比較 .......................................................................................... 13 全空氣系統(tǒng) .............................................................................................. 13 風(fēng)機(jī)盤管加新風(fēng)系統(tǒng) ................................................................................ 14 空調(diào)系統(tǒng)方案的確定 .......................................................................................... 15 第四章 房間送風(fēng)量、新風(fēng)量及新風(fēng)負(fù)荷的確定及末端設(shè)備的選擇 .................................. 16 房間送風(fēng)量的計(jì)算 ............................................................................................. 16 全空氣系統(tǒng)送風(fēng)量 .................................................................................... 16 風(fēng)機(jī)盤管加新風(fēng)系統(tǒng)送風(fēng)量 ...................................................................... 17 新風(fēng) 量及新風(fēng)負(fù)荷的確定 ................................................................................... 18 末端設(shè)備的選擇 ................................................................................................. 19 第五章 氣流組織校核 .................................................................................................... 20
