Brief introduction of temperature control method of plate heat exchanger

Introduction of plate heat exchanger manufacturers : Heat exchangers are a common type of heat transfer equipment. It can heat (or cool) the material to a predetermined temperature through it. It is a tube-and-tube heat exchanger in which the heat of the heat carrier is first transferred to the inner wall of the sleeve, and then transferred to the cold fluid after being conducted through the tube wall.
There are several series of thermal resistances in the heat transfer process, so the heat exchanger is a multi-capacity object, and the time constant and hysteresis are relatively large.
According to process requirements, the parameter to be controlled is the outlet temperature of the cold fluid after it is heated, and this temperature needs to be maintained at a set value. The main disturbance factors affecting the outlet temperature are: temperature and flow of cold fluid inlet, temperature and flow of heat carrier population. There are two common control schemes to control the heat carrier flow. This is achieved by changing the flow of the heating medium, that is, controlling the flow of the heating medium as the manipulated variable. When it deviates from the set temperature. The controller sends the corresponding control information, changes the valve opening degree, and controls the flow of the heat carrier, so that it can meet the process requirements. Because of the simple structure of this solution, it is widely used in factories. However, for a heat exchanger, the heat transfer area is constant. When the heat carrier flow rate is large enough and the heat exchange has reached saturation, the effect of increasing the flow rate to increase the outlet temperature is not significant .
