郑州市某综合大厦空调系统设计

本次毕业设计的主要内容是对郑州市某综合大厦进行中央空调系统设计。主要内容有：系统形式的选择，对各层房间的冷负荷计算、房间风量的计算和风管设计计算；水系统设计及相应的水力计算；设备选型和布置等。该建筑位于郑州市，共6层, 建筑总高度25.4m，总建筑面积7254㎡。建筑物地下一层包括车库、制冷机房、水泵房；一、二层为商场，层高为5.0m。三层为KTV歌舞厅，层高为5.0m。四、五、六层位客房，层高为3.4m。在本次设计上侧重于中央空调系统设计并且暂不考虑冬季制热问题。根据房间的功能和设计要求，风系统分别采用了全空气系统和独立新风加风机盘管系统两种；水系统采用同程式系统。本次设计参照了《旅馆建筑空调设计》，对客房部分采用了较高的设计标准，采用独立新风加风机盘管系统。这样的设计能够满足房间对新风量的要求，在过渡季节可调节新风量满足客房室内负荷的需要，从而达到建筑节能的目的，减少不必要的能源浪费。本次设计涉及到空调系统的划分，冷负荷的计算，房间气流组织计算，风管的水力计算及布置；水系统的划分，水管的水力计算及水管布置；空调设备的选型，冷冻机房设计等。

关键词：中央空调系统，负荷计算；水力计算；独立新风加风机盘管系统；设备选型；制冷站设计

Abstract

The graduation project is the main content of Zhengzhou City, the comprehensive building of a central air-conditioning system design. The main contents are: system form of the option of room on each floor of the cooling load calculation, the calculation of room air flow and wind design calculation; water system design and hydraulic calculation of the corresponding; such as equipment selection and layout. The building is located in Zhengzhou city, a total of 6 layers, building a total height of 25.4m, the total construction area of 7254 ㎡. Buildings including the garage floor, cooling the engine room, pump room; one or two for shopping malls, high layer 5.0m. Three for the KTV song and dance halls, high layer 5.0m. Four, five, six-bit room, storey to 3.4m. In this design focuses on the design of central air-conditioning system and will not consider the issue of winter heating. According to room function and design requirements, the wind systems are a whole new air systems and independent wind plus two fan-coil system; water system with the programming system. The design is based on "high-rise hotel central air-conditioning Design Manual", part of the room using a high design standards, the use of an independent air system. This design can meet the requirements of the room on the volume of outdoor air in the transitional season of fresh air adjustable so as to achieve the purpose of building energy efficiency, reduce unnecessary waste of energy. The design involves the division of air-conditioning systems, cooling load calculations, calculation of room air distribution, duct of the hydraulic calculation and layout; the division of water systems, water mains and pipes of the hydraulic calculation layout; the selection of air-conditioning, refrigeration room design

Key words:
central air-conditioning system; load calculation; hydraulic calculation; independent increase fresh air and fan coil system; equipment selection; refrigeration station design.
