1、 1 摘要摘要 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
2、室内环境得到改善，达到了设计要求。 关键词：关键词：中央空调系统；活塞式制冷机；风机盘管；新风系统 Abstract This design is about the ccntral air conditioning system engineering that locates in shenyang. There arc five floors and one floor underground. The gross floor area is about 3087.96 m2, and the air conditioning area is about 6730 m2 The cold
3、 duty is 233.2kW, TO: choose 1screw chilled water units, and the models arc（WRAT） Their maximal burning of natural 2 gas arc 277.4kW when refrigerating; According to different functions, adopting the common form of dealing air, that is fan-coil unit systems with once air return. Especially, the fres
4、h air of fan-profile and fresh air system is processed to the point whose heatcontent is the same to the appear an cc point of the room, and it doesnt hear the load of the room. In order to raise the watcrpowcr stability, making the even distribution of volume of flow, the system uses the water tank expanding to supply water and the pressure was stabilized. At the same time, in proccss of calculating, we draw the standard floor air-condition system drawing, and the water pipe system, the air
