集群控制在数据中心风冷空调中的应用
Application of cluster control to air-cooled air conditioners in data centers
摘要：
风冷直膨型精密空调广泛应用于数据中心机房。实际使用工况与设计参数存在较大差异，机房热湿环境很难达到最佳状态。介绍了一种空调集群控制方式，即通过优化气流组织，调节空调运行工况，降低风机工作时长，降低压缩机启停频率，最终实现机房热湿环境高效稳定运行。
Abstract：
Air-cooled direct expansion precision air conditioners are most widely used in data centers. Due to the large differences between design parameters and actual operating conditions, the heat and humidity environment of the computer room is difficult to achieve the best state. Presents an air conditioning cluster control method that optimizes the airflow organization, adjusts the operating conditions of the air conditioning, reduces the working time of the fan, reduces the frequency of compressor start and stop, and finally realizes the efficient and stable operation of the heat and humidity environment of the computer room.
