摘要 本設(shè)計為北京長江國際公司辦公樓中央空調(diào)系統(tǒng)，擬為之設(shè)計合理的中央空調(diào)系統(tǒng)，為室內(nèi)工作人員提供舒適的工作環(huán)境。建筑共四層，總面積為9000，首層凈高3.9m，其它層凈高3.5m。要求采用空調(diào)夏季制冷冬季供暖。設(shè)計的空調(diào)系統(tǒng)采用風(fēng)機(jī)盤管—新風(fēng)系統(tǒng)，選用冷水機(jī)組制冷凍水供冷，冬季依靠市政集中供熱。 設(shè)計內(nèi)容包括：空調(diào)冷負(fù)荷的計算；空調(diào)系統(tǒng)的劃分與系統(tǒng)方案的確定；冷源的選擇；空調(diào)末端處理設(shè)備的選型；風(fēng)系統(tǒng)的設(shè)計與計算；室內(nèi)送風(fēng)方式與氣流組織形式的選定；水系統(tǒng)的設(shè)計、布置與水力計算；風(fēng)管系統(tǒng)與水管系統(tǒng)保溫層的設(shè)計；消聲防振設(shè)計等內(nèi)容。除此之外，還需要進(jìn)行空調(diào)末端處理設(shè)備及機(jī)房輔助設(shè)備的選型。需要結(jié)合所選擇的空調(diào)系統(tǒng)的特點及辦公樓的建筑結(jié)構(gòu)選擇合適的空調(diào)機(jī)組及末端設(shè)備，合理的布置吊頂內(nèi)風(fēng)管與水管的位置。并根據(jù)所選擇的空調(diào)機(jī)組選配合適的輔助設(shè)備：冷凍水循環(huán)水泵，冷卻水循環(huán)水泵，開始水箱，冷卻塔，及相應(yīng)的水管風(fēng)管閥門等?！?/p> 關(guān)鍵詞：辦公樓；空調(diào)；風(fēng)機(jī)盤管；新風(fēng)
Abstract：The graduation project designs a central air conditioning system for chagnjiang international official building in beijing City, so as to create a comfortable work environment for the stuff.The total area of the building is 9000The height of the first floor is 3.9 meters,and the other three floor'heights are all 3.9 meter. The air-condition system is designed tosupply cool air in summer,and a fan coil units(FCUs) —fresh air system is selected and central screw water chillers are used to provide the chilling water needed.In winter,the municipal central heating system is used to supply heat and keep official room warm. It contains: cooling load calculation; the estimation of system zoning; the selection of refrigeration units; the selection of air conditioning equipments; the design of air duct system and calculation; the estimation of air distribution method and the selection of relevant equipments; the design of water system and its resistance analysis; the insulation of air duct plant and chilled water pipes; noise and vibration control; etc.Meanwhile,equirement selection is also an essential part of the design.According to the requirement,a fan coil units (FCUs) —fresh air system is appropriate.Thus, the main process equipment, i.e. the chiller,the fan coil units,the circulating water pumps,the cooling tower, are also determined in the design considerting their characteristics and working conditions. Key words: Official building; Central air conditioning; Fan coil units (FCUs);Fresh air system
