摘要
本设计为哈尔滨XX集团办公楼空调系统工程设计。哈尔XX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,。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。

Abstract
The design for the Harbin Wangjiang Design 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 . Cooling load for the 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 of 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 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 ian 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
