1、 I 摘 要 本设计为哈尔滨望江集团办公楼空调系统工程设计。哈尔滨望江集团办公楼属中小 型办公建筑，本建筑总建筑面积 4138m2，空调面积 2833m2。地下一层，地上八层，建 筑高度 33.9m。全楼冷负荷为 191 千瓦，全楼采用水冷机组进行集中供给空调方式。 此设计中的建筑主要房间为办公室，大多面积较小，且各房间互不连通，应使所选 空调系统能够实现对各个房间的独立控制，综合考虑各方面因素，确定选用风机盘管加 新风系统。在房间内布置吊顶的风机盘管，采用暗装的形式。将该集中系统设为风机盘 管加独立新风系统，新风机组从室外引入新风处理到室内空气焓值，不承担室内负荷。 风机盘管承担室内全部冷负

2、荷及部分的新风湿负荷。风机盘管加独立新风系统由百叶风 口下送和侧送。水系统采用闭式双管同程式，冷水泵三台，两用一备；冷却水泵选三台， 两用一备。 在冷负荷计算的基础上完成主机和风机盘管的选型，并通过风量、水量的计算确定 风管路和水管路的规格，并校核最不利环路的阻力和压头用以确定新风机和水泵。 依据相关的空调设计手册所提供的参数，进一步完成新风机组、水泵、热水机组等 的选型，从而将其反应在图纸上，最终完成整个空调系统设计。 关键词：风机盘管加独立新风系统； 负荷； 管路设计； 制冷机组： 冷水机组 II Abstract The design for the Harbin Wangjiang D

3、esign Group office building air conditioning system. Harbin Wangjiang Group is a small and medium-sized office building office buildings, the total floor area of building is 4138m2, air-conditioned area is 2833m2. There are eight floor of the building, building height is 33.9m. Cooling load for the

4、entire floor, 191 kilowatts, the whole floor using Central Cooling Chillers to focus on the way . This design of the main room of the building for office, most of them is very small, and the rooms are not connected, the selected air-conditioning system should be able to achieve independent control o

5、f each room, considering the various factors to determine the selection of fan-coil plus fresh air system. Arrangement in the room ceiling fan coil units, using the dark form of equipment. Set the focus on fan-coil system, plus an independent air system, fresh air from the outdoor unit to deal with

6、the introduction of a new wind to the indoor air enthalpy value, do not bear the load of indoor. All bear the indoor fan-coil cooling load and part of its new rheumatoid load. Fan-coil plus an independent air system sent by the Venetian and the under side air delivery. Closed water system with a dual-track program, three cold-water pump, dual-use a prepared; cooling pumps three elections, one prepared by dual-use. In the cooling load calculation based on the completion of the selection of host
