Tóm tắt

Abstract: This paper presents the results of research, design, manufacture and installation of PLC system combined with HMI monitor to control the refrigeration drying process combined with infrared radiation. The system is equipped with PLC Module S7 - 1200 connected to the HMI - KTP400 screen along with wind speed measuring devices, temperature and humidity sensors, mass sensors to help control and monitor parameters: temperature, air velocity, mass of drying material. The research results are transferred to serve the training and scientific research at the Thermo - Refrigeration Laboratory, Nha Trang University.
