摘要
本工程为供电公司，建筑面积共计7000mm2,地上6层，地下1层，建筑高度31.2m。 地下室为设备用房，一层为电子会议室、休息室、调度电源室等，二～六层为办公、资料 室等。要求对办公、会议、休息、走廊等区域进行空调设计；对卫生间、地下室设备用房 等进行通风设计；进行全楼空调用冷热源设计。通风空调设计面积约7000m2。
本设计包括空调系统、通风系统、冷热源系统等设计。根据本课题的实际情况，初定 空调方案及形式，系统划分，冷热源选择布置，空调方式，水系统等。
系统的划分为：一层除电子会议室外加2-6层其他房间由于各房间面积不是很大，且 房间功能都相似，半集中式空调系统恰好能很好的满足这些房间的要求，因此全都选用半 集中式空调系统中的风机盘管+新风系统，对于一层中的电子会议室，由于其面积大，人 员多，因此采用全空气系统。对于卫生间夏季对温度调节的要求不高，在卫生间域中只安 装通风设备，而不设置制冷系统。
冷热源选择布置:冷热源选择水冷式半封闭双螺杆式制冷机组和城市热水管网 水系统形式：拟采用双管制闭式异程式系统。双管制系统简单、初投资少。闭式水系 [版权所有：http://DOC163.com]
统中冷冻水或热水在系统内密闭循环，不与大气接触，管路系统不易产生污垢和腐蚀，并 且系统简单、水泵耗电量较少。异程式系统的特点是节省管材，管路简单。
通风方式：采用自然通风与机械通风相结合的方式。在符合自然通风条件的地方，采 用自然通风；在条件不符的地方，采用机械通风或自然通风与机械通风相结合的方式。
