1、河南科技大学毕业设计I西安龙泉大酒店空调工程设计摘 要暖通空调设计主要是对室内热环境、空气品质进行设计，但这必须在充分了解建筑对暖通空调的要求和暖通空调系统及设备对建筑及其它设施的影响的基础上进行设计。该建筑位于西安市，本工程为酒店空调工程设计,酒店高约33米，是一座综合性建筑物,总建筑面积为9120,其中空调面积为8973。酒店主楼地面10层,其中一层为商铺，层高为4.5米，二、三层为雅间、多功能厅, 层高为3.2米，其余四到十层为办公室、标准间，层高为3.2米。结合建筑的特点，夏天采用螺杆式冷水机组作为冷源，冬季采用城市供热管网通过换热器得到热水，以达到节约运行成本的目的。对于雅间、标准间
2、等小空间采用风机盘管加新风系统，每层设有新风机组，可以由同层的新风机组送入室内，风机盘管独立承担室内的冷热负荷。风机盘管的新风供给方式用单设新风系统，独立供给室内。而对于多功能厅、商铺等空间较大、人员较多、温度和湿度允许值波动范围小的房间，采用全空气系统。因为该酒店房间类型繁多，各房间冷热负荷并不相同，可以个房间进行个别的调节。本设计空调水系统选择闭式、竖直异程、水平同程式、双管制、单级泵，变流量系统，这种空调水系统具有结构简单，初期投资小，管路不易产生污垢和腐蚀，不需要克服系统静水压头，水泵耗电较小等优点。关键词：空调系统，冷负荷，水系统，独立新风系统，风机盘管河南科技大学毕业设计IIABS
3、TRACTHVAC design is mainly for indoor thermal environment, air quality in design, but construction must be fully aware of the requirements for HVAC and HVAC systems and equipment for construction and other facilities on the basis of design. The building is located in xian.The project is the hotel ai
4、r-conditioning engineering design .The hotel is a comprehensive building, The total building area is 9120,but the air-conditioning area is 8973.There are 10 floors of the building . The first floor is for shops which height of the first floor is about 4.5meters.Other layers of the building is 3.2 me
5、ters hight .The second and third layers is for Blair and the multi-function hall.And the remaining 4-10 layers is for office room and guest room.Combine the characteristics of the construction .In summer, we use water-cooled chillers as a cold source . In winter,we use hot water pipe network of city
6、 as a source . In order to savings the operating cost. For accor and the standards room, such as small space we use the fan coil and new wind systems, There is one new air unit each layers so that fresh air can be into the indoor and fan-coil bears the indoor cooling load . Fan-coil and fresh air in
7、dependent supply into room. As for the multi-function hall and shops, such as larger room, more staff, allowed temperature and humidity fluctuations in little,if you set the fan-coil water system will use more end equipments, resulting in a waste of investment. So the entire air system to be adopted
8、. Because of the different types of hotel rooms, the room is not the same as hot and cold load can be individual rooms regulation. The design of air conditioning water systems use closed, vertical different way, the level of the same programs, dual control, single-stage pumps, variable 河南科技大学毕业设计III
9、flow system. Air-conditioning water system that is simple in structure, the initial investment, not easy to have a pipeline dirt and corrosion, the system does not need to overcome the hydrostatic pressure head, water pumps, small power consumption and so on.KEY WORDS: air-conditioning systems, cool
