淮北蓝天酒店位于安徽省淮北市，一个地下一层，地上十层的客房为主的建筑。地下室设为停车库，一层有迎宾大厅和厨房，二层有大厅和办公室，三到十层为客房，房型一样。
此次设计的主要内容包括：对建筑功能的划分和使用要求，客房的通风设计。由概算结果确定各建筑功能房间的设计标准和设计方案，查找当地各种设计参数和设计标准，通过计算分析，确定最优方案。5679
本设计计算部分从整栋楼的冷负荷计算开始，为了能够对冷负荷有全面的认识，此次设计采用计算法。从系统合理、选型合适、能源损耗等角度出发，并对宾馆中每一种类型的房间进行分析，从而得出合理的冷负荷。
在了解建筑物概况及设计参数、冷负荷的情况下，对系统方案进行初步确定：由于该宾馆层数较少，使用人员不多，制冷负荷较低，我们选择半集中式中央空调系统。为了更好，更经济的对房间承担冷负荷及湿负荷，选取空气水系统的设计方案。具体设计按送风参数的数量，送风量恒定与否，所使用空气来源和房间的控制要求设定。通过计算，系统总的制冷量为404kW,制冷机组采用螺杆式冷水机组一台，制冷量为430kW的,根据房间的功能，全楼采用一次回风系统和风机盘管加独立新风系统，因为这种布置比全新风系统节省能源，而且容易调节，房间的排风采用自然排风方式，特别是风机盘管加独立新风系统的新风处理到室内状态点的等焓线上，直接送到室内，不承担室内负荷。在水系统设计上，我们参考了国内外多个实例，根据本宾馆建筑冷负荷较小，面积中等以及当地气候条件等决定采用异程闭式系统，并在系统最高点设置膨胀水箱。
在完成方案的确定后，进行风系统和水系统的阻力计算，在计算过程中，综合经济因素，质量因素等确定管材，确定风管水管管路路径，得出最不利路径的阻力，结合冷负荷，送风量等选择相应的空调末端产品以及辅助设备。
在设计过程中，查找各种厂家产品样本，了解当今本专业制造水平，并遵循暖通空调设计相关的准则与法规，讨论本设计遇到的问题，并总结经验教训。根据设计的过程及计算结果运用CAD绘制标准层空调系统平面图，水系统图，风系统图，轴测图。
General description of the design
Blue Sky Hotel is located in Huaibei City, Anhui Province, a basement, ground floor rooms ten main buildings. Set the basement parking garage, a layer of a welcoming lobby and kitchen, second floor hall and office, three to ten layers as the room, the same room.
The design of the main contents include: the pision of architectural features and usage requirements, room ventilation. The results determined by the budget of the building function room design standards and design, find a local variety of design parameters and design criteria, the calculation and analysis to determine the optimal solution.
This design calculation part from the whole building cooling load calculation begins, in order to be able to have a comprehensive understanding of the cooling load; the design uses the method of calculation. From the system is reasonable, appropriate selection, energy loss, and other point of view, and hotel rooms for each type of analysis to arrive at a reasonable cooling load.
Description and in the understanding of building design parameters, the cooling load in the case of system solutions for preliminary determination: As the low-rise hotel, with few staff, the cooling load is low, we chose semi-centralized central air conditioning system.
In order to better and more economical commitment of the room cooling load and wet load, select air water system design. Specific design parameters according to the number of air, or a constant air volume, using the source and the room air control requirements set. By calculation, the total system cooling capacity of 404kW, refrigeration unit uses a screw chillers, cooling capacity of 430kW, depending on the function of the room, the whole floor using a return air systems and fan coil plus independent air system, Because of this arrangement than the fresh air system to save energy, but also easy to adjust the room exhaust ventilation using natural methods, particularly independent air system fan coil air handling new state point to the indoor enthalpy online, directly to the indoors, do not assume the indoor load. In the water system design, we refer to multiple instances of domestic and foreign According to the hotel building cooling load is small, medium in size, and local climatic conditions vary Cheng decided to use a closed system, and the highest point in the system settings expansion tank. 蓝天酒店中央空调系统设计说明书+CAD图纸:http://www.youerw.com/gongcheng/lunwen_2817.html
