内蒙古科技大学 本科生毕业设计说明书 题 目：空调学生姓名：学 号：专 业：建筑环境与设备工程 班 级：建环0-1 指导教师：牛永红 空调系统设计 摘 要 本设计为空调系统设计。本建筑共8层，总建筑面积8900，总层高32m。全楼采用集中供给空调方式，机房中设置两台水冷单螺杆式冷水机组。 根据各不同的功能房间，将该集中系统分为两种空调送风方式：一、 二、 三层采用全空气系统，由空气处理机组处理送风，其中、乒乓球室、健身房及餐厅采用圆形散流器平送的送风方式。四至八层采用风机盘管加独立新风系统，新风直接从室外引进新风机组，经过过滤、冷却或加热、加湿、送风机加压、处理到室内状态点后直接送入房间，不承担房间冷负荷；各房间均选用双层百叶风口进行侧送风。水系统采用闭式双管异程式，冷却水泵三台，两备一用；冷冻水泵三台，两用一备。 根据各种计算结果，通过性价比分析，进行了设备选型，确保设备容量、压强、噪声等方面满足要求。本空调系统的设计力求达到经济、舒适、方便、实用，并尽可能满足节能要求。 关键词：风机盘管加独立新风系统全空气系统散流器选型 Abstract This project is the design for an apartment with air-conditioning system in Beijing .The total area is 8,900 square metres,which contains 8 stories and 32 metres.The concentrated air-conditioning system is used in this building and two single screw-type water-cooled chillers are set up in equipment room. According to the functions of the various rooms, the concertrated air-conditioning system is divided into two aparts: the first three stories including badminton, table tennis room, gym and restaurants are controlled by all-air systems.The air controled by the air handling units is diffuseed with flat delivery of the air supply mothde. Four to eight layers are controlled by PAU+FCU system. Fresh air is diffused directly from outside into the room after filtration, cooling or heating, humidification, blower pressure, treatment to the interior point ,which does not take the room cooling load;All rooms are used for double-side air outlet louvers Water system of different closed programs is used,which contains 3 cooling water pumps,two are used one is reserved; 3 chilled water pumps, two are used one is reserved. According to various calculations and cost analysis, equipment selection carried out to ensure the demand of the equipment capacity, pressure, noise and so on. The design of air-conditioning system seeks to achieve the goal of economic, comfortable, convenient, practical, and energy-saving as much as possible. Key words: PAU+FCU system;the entire air system;san converter;
