某综合办公楼暖通空调系统设计

摘要

本文对某综合办公楼暖通空调系统进行设计，对于每一环节的设计，都要提出几种预选方案并比较各个方案的优缺点及进行经济技术分析，最终得到最优方案，来达到办公楼暖通空调设计要求。针对设计过程中出现的问题我也提出一些切实可行的解决办法并改善方案。

建筑对象为某综合办公楼，一至三层为裙房，房间类型有中庭、餐厅、办公室、配电室、IT中心，四至十二层以办公室为主，考虑到房间类型和使用时间，空调系统采用的是风机盘管加新风的形式，对于个别不需要新风的房间只采用风机盘管提供冷量即可。制冷机房单独布置，采用两台螺杆式制冷机组，由于冷热负荷相差不大，流量接近两倍，故分别设置冷热水泵，机房有板式换热器进行市政热网与二次侧换热，用于冬季采暖供水。设计中有一些必须注意的问题，如风管水管的布置，风机盘管选型，制冷机房的布置是否合理，应结合实际施工情况来确定设计方案。

整个暖通空调系统的设计遵守了相关的国家设计规，对配套设备的选择也查阅了大量的设计手册和样本，而且通过经济技术的比较，最终确定了合理的设计方案、设备选型，并完成了有关施工图的绘制。在本文中详尽地说明了设计原理和方法，涉及到的具体数据也都反映在了本文中。

THE HVAC SYSTEM DESIGN OF A

GENERAL OFFICE BUILDING IN

BEIJING

Abstract

This paper on the design of the HVAC system of a general office building in Beijing, for every aspect of the design, I have proposed several preliminary scheme and compared the advantages and disadvantages of each scheme, made technical and economic analysis, finally get optimal solution to achieve the office building HVAC design requirements. In view of the problems in the design process, I also put forward some practical solutions to improve the program.

Construction object for a comprehensive office building in Beijing, one to three layers for the podium, room type has the atrium, restaurant, office, transformer room, IT center, four to ten in the office on the second floor is given priority to, considering the room type and use time, air conditioning system is fan coil plus fresh air in the form of, for the individual does not need to use only fresh air in the room fan coil units provide cold energy can.Refrigeration equipment room arrangement separately, using the two screw refrigeration unit, due to the cold and hot load were similar, traffic nearly two times, hot and cold water pump

were set up respectively, equipment room inside the plate heat exchanger for municipal heat supply network and the secondary side heat transfer, used for water supply of heating in winter.There are some must pay attention to in the design of problems, such as duct pipe layout, selection of fan coil units, refrigeration room layout is reasonable, should be combined with the actual construction situation to determine the design scheme.

The HVAC system design comply with the relevant national design specification, selection of equipment have access to a lot of design manual and sample, and through the comparison of technology and economy, and ultimately determine the reasonable design, equipment selection, and the completion of the construction plans of the rendering. this paper illustrates the design principle and method in detail, and the related specific data are also reflected in this paper.
