1、摘要本设计为沈阳某综合楼空调系统工程设计，共五层，建筑总面积3087.96㎡，空调面积为。通过计算，系统总的制冷量为233.2KW,制冷机组采用活塞式空冷制冷机一台，型号（WRAT）1202，制冷量为277.4kw,根据房间的功能，全楼采用一次回风系统和风机盘管加独立新风系统，特别是风机盘管加独立新风系统的新风处理到室内状态点的等含线上，直接送到室内，不承担室内负荷。为了提高水力稳定性，使流量均匀分配，水系统管路采用膨胀水箱补水和定压。同时，在相应的计算过程中，根据设计的过程及计算结果运用CAD绘制标准层空调系统平面图，水系统图，风系统图。通过本次设计是室内环境得到改善，达到了设计要求。关键词
