北京紫金大酒店空调工程设计

Air Conditioning System Design of Zijin Grand Hotel in Beijing

根据给定的紫金大酒店的资料,设计该酒店的空调系统.结合酒店的特点,夏季采用螺杆式冷水机组作为冷源,冬季采用城市供热管网通过换热器得到热水.对雅间、标准间等小空间采用风机盘管加新风系统;对大堂、宴会厅等空间较大、人员较多、温度和湿度允许值波动范围小的房间,采用全空气系统.空调水系统选择闭式、竖直同程、水平异程式、双管制、单级泵,变流量系统.这种空调水系统具有结构简单,初期投资小,水泵耗电较小等优点.

This paper is on the design of the air conditioning system of the Zijin Grand Hotel based on the related information provided. To address the characteristics of the hotel, water - cooled chillers are used as the cold air source in summer and the urban hot water pipe network as the heating source in winter. For less spacious private and standard rooms, the combination of fan coil and new wind systems is adopted. For the spacious areas such as the lobby and ban- quet halls, which contain more people and feature slight temperature and humidity value range, the all - air system is supplied. The water system of the air conditioning is enclosed with paral- lel vertical ways, horizontal direct resturn system, dual control, single - stage pump, and a variable flow system. This system has the advantages of simple structure, small initial invest- ment, and less pump power consumption.
