本文介绍了应用于实验教学和科学研究领域的中央空调空气处理系统上位监控和工况模拟技术。整套系统采用LonWorks 总线技术实现机电设备控制和过程信号的采集与处理,在空气处理区域,采用多段加热和加湿方法,在同一时刻模拟不同回风模式下的冬夏季制热/制冷工况。
This paper introduces the supervisory control and condition simulation technology of the central air conditioning air handling system used in the field of experimental teaching and scientific research. The whole system uses LonWorks bus technology to realize the control of electromechanical equipment and process signal acquisition and processing. In the area of air treatment, the heating and humidification mode in winter and summer under different return air modes are simulated at the same time by multi-stage heating and humidification method.
