内蒙古某金融数据中心空调系统设计
Air conditioning system design for a financial data center in Inner Mongolia
摘要：
介绍了内蒙古地区某金融数据中心采用间接蒸发冷却空调机组和风冷冷水系统的双冷源空调系统工程案例。结合内蒙古地区的气候条件,对系统的整体架构进行了阐述,并对系统节能性进行了详细分析,以期在内蒙古地区实现电能利用效率(PUE)和水资源利用效率(WUE)的“双低”目标。利用仿真软件对机房内的气流组织进行了模拟仿真,结果表明,机房内空调无论在哪种工况下运行,房间温度皆分布均匀。机房热环境评价指标参数中,供热指数(SHI)值接近0,回热指数(RHI)值接近1,机房气流组织良好,空调送风效率高,机柜无热点。
Abstract：
This paper presents an application case of a dual cold source air conditioning system with indirect evaporative cooling air conditioning unit and air-cooled chilled water system in a financial data center in Inner Mongolia. According to the climate conditions of Inner Mongolia, the overall structure of the system is described, and the energy saving of the system is analysed in detail in order to achieve the “double low” goal of power usage effectiveness (PUE) and water usage effectiveness (WUE) in Inner Mongolia. The simulation software is used to simulate the air distribution in the data room. The results show that the temperature distribution in the room is uniform no matter under which operating condition of the air conditioner in the data room. In the thermal environment evaluation index parameters of the data room, the supply heat index (SHI) value is close to 0, and the return heat index (RHI) value is close to 1. The air distribution in the data room is good, the air supply efficiency of the air conditioner is high, and the cabinets have no hot spots.
