摘要:随着社会的发展以及人民生活水平的提高,越来越多的人在使用空调技术,以营造健康舒适的生活环境。

   本设计为苏州安泰广场地源热泵空调系统设计,共六层,建筑总面积9500m2,空调面积约7000m2,全楼冷负荷为486千瓦,根据房间功能,全楼采用地源热泵系统进行集中供给空调方式。系统设为风机盘管加独立新风系统,新风机组从室外引入新风处理到室内空气焓值,风机盘管承担室内全部冷负荷及部分的新风湿负荷。风机盘管加独立新风系统百叶风口侧送。水系统采用闭式双管同程式,冷水泵三台,两用一备;冷却水泵选三台,两用一备。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。

   依据相关的空调设计手册所提供的参数,进一步完成新风机组、水泵、热水机组等的选型,从而将其反应在图纸上,最终完成整个空调系统设计。

Abstract:With the development of society and the increasing of living standard, more and more people are using the air-condition technology, which built a healthy and comfort habitation for people.

   This design is about antai hotel that locates in suzhou. There are 6 floors. The gross floor area is about 9500 m2, and the air conditioner area is about 700 m2. The cold duty is 486 kW .We choose ground sourse heat pump for air-condition of this building. The system adopts the PAU+FCU system. FCU system deals with the fresh air. PAU system carries on the whole cold duty and part wet duty. PAU+FCU systems can send air from the side and the upside; it uses the circular air diffuser to supply air. There are three water-cooling pumps; two can be used when heating. In summer, two of the two is for using and another for preparing; in winter, two for using and one for preparing. The system in washroom can ventilate by itself.     The water system is divided into four parts: the first part is the underground room, the second part is the equipment room, the third part is the first and second floor, the fourth part is the standard floors that is the third floor and above.

Key words: PAU+FCU systems; load; pipeline design; refrigeration machine
