毕业设计说明书（论文）中文摘要本设计为某行政楼空调系统设计。每层净高均为 3.5m。建筑总冷负荷为 628129.13W ， 总 热 负 荷 为 1075954.71W ， 冷 指 标 为 167.25W/m2，热指标为 68.46W/m2。根据各房间大小、功能等具体情况，在负荷计算的基础上，通过空调方案比较，采纳了风机盘管加新风系统。风机盘管为卧式暗装，新风不承担室负荷，室回风与新风混合后送出。室送风，房间采纳侧送风方式。水系统采纳闭式异程两管制系统。选用了风冷热泵机组，到达夏季供冷、冬季供热的效果。水管用泡沫橡塑保温，风管采纳离心玻璃棉。设计工程中考虑了消声、减振和防火排烟的措施。关键词行政楼，中央空调系统，风机盘管加新风系统，风冷热泵机组Title A design of Hefei administrative building air conditioning system AbstractThe design for the design of air conditioning system in an administration building in hefei.Each layer height was 3.5m. The total building cooling load is 628129.13W, the total heat loadis 1075954.71W, the cold index is 167.25W/m2, the heat index is 68.46W/m2. According to the size of each room , features and other specific circumstances, on the basis of load calculation, comparing the different air conditioning program, I choose a fan coil plus fresh air system . The fresh air doesn’t undertake indoor load and delivers air after mixing the return air in the horizontal recessed fan coil. The entire air system for a return air system. For indoor air supply,the handled air is delivered by sidewall air supply. Water system adopts closed two different controlsystem.I select Air-cooled heat pump units to arrive summer cooling, winter heating effects.The thermal insulation material of water pipe and air duct are foam plastics and centrifugal glass wool respectively. Measures of noise elimination, damp, fire prevention and smoke extraction is considered during the design.Keywords administrative building, central air...
