摘要(Abstract):

从研究U型管换热器传热性能的目的出发建设了一套以热响应原理为理论基础的实验系统,介绍了实验设备与仪器仪表的选型、计算与安装。利用集散型计算机控制技术(DCS),把土壤源热泵实验系统建设成一个三级分布式计算机数据采集和控制(SCADA)系统。结果表明,该系统可以保证整个系统安全稳定运行,保证检测的数据可满足科研要求,具有一定的推广意义。
It was introduced that how to choose 、calculate and fix equipments and instruments of the experiment.A three stage distributed computer supervisory control and data acquisition(SCADA) system adopting DCS was designed.Adjust results show that this system can provide a reliable guarantee on safety operation,measure the data satisfying the request of science research.It is significant to extend to study and science research.
