毕业设计 北京市南通大厦空调工程设计 The Air conditioning engineering design Nan Tong Building, Beijing 长 春 工 程 学 院 摘 要 本设计为北京市南通大厦中央空调设计，根据已学暖通的专业知识及查阅相关设计手册，首先完成了空调冷、热、湿负荷的计算，送风量、新风量的确定，风机盘管、新风机组的选择，空调水系统、风系统的水力计算，冷源、水泵、换热器、水处理装置的选择，以及走廊和楼梯间前室防排烟系统的设计等内容。 　　北京南通大厦Abstract The design for the Beijing Nan Tong Building for central air conditioning design, based on the expertise and have access to relevant learning design manual complete with air conditioning hot and cold, wet load calculation, air, fresh air is determined, fan coil units, air handling units of the new hydraulic selection, air conditioning system, air system calculations, select the cold source, pumps, heat exchangers, water treatment plant, as well as the design front room corridors and stairwells of smoke control systems and other content. Beijing Nan Tong Building upstairs thirteen, air conditioning room in the negative layer. To the second floor is a business rooms, three are normal office space, four to eight is chief rooms, nine to twelve layers are director offices, thirteen are activity center and meeting rooms. The whole building is relatively complex function, control is relatively difficult. Therefore, the use of air fan coil semi centralized air conditioning system. Summer temperatures are relatively low, and the use of air conditioning shorter. Taking these reasons, the design of summer cold source module using air source heat pump chillers. The purpose of this energy-saving play, but also reduce operating costs Party.
