Implementation of a PI Controller in a Helical Falling Film Evaporator Model

https://doi.org/10.58571/CNCA.AMCA.2023.089

Resumen: This work presents the implementation of a PI controller for a falling film evaporator model, which is part of an Absorption Heat Transformer (AHT). The evaporator control aids the process to maintain adequate performance which benefits the heat produced in the absorber to obtain high performance in the AHT. In this research, the evaporated mass flow rate was controlled by manipulating the mass flow rate flowing inside of the tubes to reach a certain heat transfer rate to evaporate a load of fluid flowing outside of the tubes as a falling film. The control is performed with a PI controller and a proportional controller with an adjusted bias. Additionally, disturbances are applied in the input temperature to simulate the temperature coming from industrial waste heat. This work can be a reference to control the falling film evaporator when it is coupled in the AHT and in other research such as in control of evaporators in the dairy industry.
