Understand the operation control of heat exchanger

In order to make the heat exchanger have a strong heat exchange effect, and for the use efficiency of the equipment, the operation control will be carried out in the use process. Through the operation control of heat exchanger, we can make full use of the heat generated each time. In short, it is also for the overall heat exchange effect. So in the use process, how should we do a good job in the operation control of the equipment? There are two ways to do this:

1. The traditional PID control is still used in the operation control of heat exchanger. The control system is composed of the flow of heating medium as the regulating means and the outlet temperature of the heated process medium as the controlled variable. For the applications with large load interference and high control quality requirements, the feedforward control with load interference is often used to form the feedforward feedback control system.

2. The conventional heat exchanger controller has poor adaptability and low control precision to this kind of large inertia, time lag and nonlinear system, which not only affects the product quality, but also causes energy waste, and is difficult to ensure the ideal control effect. Therefore, it is of great significance to find a better control method for improving control quality and saving energy.

The operation control of heat exchanger is not only conducive to the efficient use of equipment, but also can play its role in different places, and can save part of energy and reduce unnecessary heat loss. So from these advantages, we should control the operation of the equipment to reduce unnecessary waste. So that it can quickly adapt to the use of various industries.
