Diseño, simulación e implementación de un prototipo de ciclo de refrigeración controlado por un PLC SIEMENS 1200 y HMI

Abstract

This project consists of control programming for a refrigeration cycle implemented in a programmable logic controller. The variables, operating sequences and control conditions necessary for the refrigeration system to operate correctly must be defined. A graphical interface is created on an operator panel (HMI) to visualize and control the refrigeration cycle. Displays, buttons, indicators and alarms must be designed so that operators can monitor and adjust the refrigeration system in an intuitive way. A prototype of a refrigeration cycle is prototyped, for which a prototype of the refrigeration system that has been designed in the PLC and HMI is fabricated. The appropriate components, such as compressors, condensers, evaporators and temperature sensors, must be selected and connected according to the design. Then, the PLC programming is done and the program is loaded into the PLC so that the prototype works and its performance and efficiency can be tested in real conditions
