Change the control settings of the method, the response as soon as possible in the process of the system lags behind be the smallest system overshoot. Controlled by two PID (PID is a variable in each group) control loop structure, known as the two sets of control loops: the main circuit and from the circuit, the main control loop from the loop output as the settings. The system with feedforward with PV, the master PID loop operation results of the PV output and feedforward signals as the composite of the settings from the control loop, through such control of the temperature gradient, to ensure the accuracy of temperature control system. Typical application of refrigeration heating temperature control system Dynamic thermostatic control of cold and heat source of high pressure reaction kettle, dynamic thermostatic control of double layer glass reaction kettle, and dynamic thermostatic control of cold and hot source of double-layer reactor. Microchannel reactor thermostatic control, small temperature control system, steam - feeding system temperature control, material low temperature aging test. The thermostatic control of the combined chemical cold source heat source, the cooling heating of the semiconductor equipment and the heating temperature of the vacuum chamber are controlled. Advantages and functions of temperature control system of refrigeration Temperature range from 120 to 350, performance superior, unique, high - precision, intelligent temperature control. High cooling power from 0.5 to 1200kW, highest production stability and repeatable results.
