The TCU temperature control system uses the method of changing the control setpoint to quickly respond to the system lag in the process to obtain a small system overshoot. Its control consists of two sets of PIDs (each set of PIDs is variable), and these two sets of control loops are called: master loop and slave loop, and the control output of the master loop is used as the set value of the slave loop. The TCU system adopts the method with feedforward PV, and the output of the PID operation result of the main control loop is combined with the feedforward PV signal as the set value of the slave control loop, and the TCU controls the temperature change gradient to ensure the temperature control accuracy of the system. (General anti-hysteresis cascade control).
The TCU Temperature Control System Temperature Control Unit uses existing thermal energy to be integrated into a single fluid system or secondary circuit to control the temperature of the process equipment. After completing the flow of only one heat conduction liquid into the jacket of the reaction vessel, the temperature of the reaction process can be controlled by the entire TCU temperature control system. With the TCU temperature control system, users can get a closed, repeatable temperature control over a wide temperature range, which can achieve -80 degrees Celsius to 200 degrees Celsius, with a wide temperature range and higher accuracy.
The main circulation circuit of the temperature control unit of the TTCU temperature control system is composed of a high-efficiency heat exchanger, an expansion tank, a circulating pump and related pipelines, and the shell is made of metal plates, and the control box is directly installed on the water tank. The temperature of the whole reaction process is controlled through accurate calculation, and a standardized interface is reserved, and the heat exchange module of cold and heat sources can be added according to actual needs. In addition, the TCU temperature control system can be selected to control the reaction process temperature and single fluid temperature, and the temperature difference between the reaction process temperature and the thermal conduction single fluid temperature can be set and controlled, which can be used for recipe management and production process recording.
