1、 1 北京市某饭店通风空调设计 摘要 本设计为北京某十层饭店空调工程设。该楼的工程概况为：总建筑面积约 13132m，高 37.4m, 地上十层，地下一层。 空调设计中，一至三层的大空间（大堂、西餐厅、宴会厅等）采用全空气一次回风的空气处理方 案。空气处理机组采用超薄吊顶式空气处理系统。其余空调房间（中餐厅、客房、贵宾房等）采用风 机盘管加新风系统。新风由设置在走廊内的吊顶新风机组处理后送入各房间。 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。 空调用制冷机房设在地下室，选用两台螺杆式冷水机组

2、。夏天使用冷水机组提供的 7/12的冷 水。水管路采用两管制。 关键词：空调设计，全空气系统，风机盘管系统，冷水机组 2 Design of Ventilating and Air Conditioning for restaurant in Beijing Abstractbstract The air conditioning engineering of one Hotel with ten layers in Beijing was designed.
