1、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荷及部分的新风湿
2、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AbstractThedesignfortheHarbinWangjiangDesignGroupofficebuild
