内蒙古科技大学 本科生毕业设计说明书 题 目：北京市某楼空调设计 北京某楼空调系统设计 摘 要 本设计为北京某楼空调系统设计。全楼采用集中供给空调方式，机房中设置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：采用全空气系统，由空气处理机组处理送风。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。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选型 Abstract The design for the design of a building air conditioning system. This project is located in the Beijing area, 1 basement garage and equipment rooms, 6 floors, a layer of shopping malls, two to six-story hotel, with a total construction area of about 7000 m2. The whole building air conditioning, centralized supply three water-cooled single-screw chiller set in the engine room. According to the various function rooms, the centralized system is divided into two air-conditioned air supply: shopping malls, dining hall, balcony, full air system, air supply air handling units processing. Rooms with independent air system, fan coil, fresh air directly from the outdoors to the introduction of new air handling units, filters, cooling or heating, humidification, blower pressure to deal with the indoor state point directly into the room, does not assume the room cooling load. Results according to various calculations, cost analysis, equipment selection, to ensure that the equipment capacity, pressure, noise, etc. to meet the requirements. The air conditioning system design seeks to achieve economic, comfortable, convenient, practical, and, as far as possible to meet the energy requirements. Key words: PAU+FCU system;the entire air system;diffuser Selectio 目 录 摘 要 I Abstract II 第1 章 绪 论 1 第2章 原始资料 3 2.1工程概况 3 2.2土建资料 3 2.3气象参数 4 2.4室内设计参数 4 2.5设计依据 4 第3章 空调冷负荷计算 5 3.1夏季逐时冷负荷计算公式 5 3.1.1外墙和屋面瞬变传热引起的冷负荷 5 3.1.2内围护结构冷负荷 5 3.1.3玻璃窗瞬变传热引起的冷负荷 6 3.1.4透过外玻璃窗日射得热引起的冷负荷 6 3.1.5 设备散热形成的冷负荷 6 3.1.6照明散热形成的冷负荷 7 3.1.7人体散热形成的冷负荷 8 3.2湿负荷计算公式 8 3.2.1人体散湿量 8 3.2.2散湿量敞开水表面散湿量 9 3.3各项逐时冷负荷汇总表 9 3.4 空调系统新风冷负荷的确定 9 3.4.1空调系统和空调室内新风量的确定 9 3.4.2空调室内新风负荷和空调系统新风负荷的计算 13
