摘 要
本设计为 某办公综合楼空调设计，建筑地下一层，地上十二层。地下一层为设备房和停车库，地上一层为营业大厅，二层为会议室，三层为餐厅，四至十二层为办公场所。
根据建筑功能特点，选取全空气系统和风机盘管+独立新风系统的空调方式， 对于会议室等大空间采用全空气系统，接待，办公等较小的空间就用风机盘管+独立新风系统， 独立新风+风机盘管的空调方式是由风机盘管承担室内冷负荷，而新风负荷由各层新风机组来承担，新风通过新风机组处理到与室内等焓值的状态，直接送入房间。
公共卫生间设置排气系统，冷水机组布置在地下一层机房内。针对地下一层的实际使用情况，系统设计了排风方案，采用机械进风和机械排风系统。
关键词： 风机盘管加新风系统 空调水系统 排风排烟系统

Abstract
The design of air conditioning design and construction of a Nanjing official building is 12 layers, including the basement rooms for the equipment and storage rooms.The first floor is , number two is meeting room，number three is dining room，
Number four to twelve
for the 0ffices 。
According to construction features, to select the entire air system and air system with fan coil and independent, and to select a fully integrated air system for the big meeting room, office and other small space on the disk with fan Pipe + independent air system is the proper selection.Independent fresh air and fan coil fan coil air-conditioning mode is borne by the indoor cooling load, and the new wind load from the floors bears the new air units. The new air handling unit through the fresh air makes it to the enthalpy and interior space and other state, which is directly into the room.
The public bathroom are setting exhaust system. Water chillers are set in the basement of the engine room layout. For the practical use of the basement, the ventilation system design programs are used with the mechanical ventilation and mechanical ventilation system.
KeyWords：Air distribution primary air fan-coil system and independent Air condition water system Line up the breeze row smoke system
