冷雾加湿控制系统与空调集中控制系统的集成

Integration of Cold Atomizing Humidifying Control System and Air Conditioner Centralized Control System

制丝线空调系统采用蒸汽加湿方式,在每年的春夏或夏秋换季季节,存在着蒸汽、电能浪费,温湿度指标不稳定的问题,为此,采用高压冷雾系统对空调加湿系统进行了改进。提出了高压冷雾加湿控制系统与制丝空调集中控制系统的集成方案,并探讨了Modbus地址与高压冷雾PLC S7-200地址的对应关系,实现了集中监控功能。实际运行表明,高压冷雾加湿集中监控系统性能稳定可靠,缩短了制冷机的运行时间,在春夏或夏秋换季季节,中央空调系统节约电能约5.702×105kWh,节约蒸汽约4500 t,达到了高效、节能的运行目标。

The air conditioning system in primary processing department with steam humidifier presents some problems, such as waste of steam and electric power and fluctuations of temperature and humidity during the turn of seasons from spring to summer or from summer to autumn. The humidifying system was improved with a high pressure cold atomizing system. A scheme integrating the control systems of high pressure humidifier and air conditioning system was proposed, the mutual relation between address in Modbus and address in PLC S7-200 of humidifier was discussed for the implementation of centralized monitoring. The practical operation showed that the centralized monitoring system works stably and reliably, it cuts the running time of refrigerator, reduces the energy consumption of centralized air conditioning system by 5. 702 × 10^5 kWh and steam consumption by about 4500 t during the turn of the seasons from spring to summer or from summer to autumn.
