Study and Control of an Industrial Cooling System Based on a Chiller Using TIA Portal

Abstract

This dissertation presents a comprehensive study of an industrial cooling system using a chiller, addressing both theoretical and practical aspects. The first chapter introduces the fundamental principles of chilled water systems, including thermodynamic laws, refrigeration cycles, and the main components of chillers. The second chapter focuses on industrial control systems, highlighting the role of Programmable Logic Controllers (PLC) and Supervisory Control and Data Acquisition (SCADA) systems in automation and monitoring, ensuring reliability and energy efficiency. The third chapter presents the practical implementation, where a chiller control system was designed and simulated using the TIA Portal platform. Ladder Logic programming was developed to integrate sensors, pumps, and compressors in a safe and efficient control sequence. This work demonstrates the importance of integrating thermodynamic engineering with modern automation technologies to achieve intelligent, efficient, and reliable industrial cooling systems.
