Course I : it introduces the fundamental principles of cryogenic and refrigeration systems, focusing on thermodynamic concepts such as phase change, entropy, enthalpy, superheating, and subcooling. It explains the vapor-compression refrigeration cycle and the role of its main components, while also presenting refrigerant fluids, their environmental impact, and system performance evaluation using the coefficient of performance (COP), linking theory to practical engineering applications.
Course II: This chapter presents advanced concepts and applications of cryogenic systems, integrating the importance of vacuum technology in minimizing heat transfer and ensuring efficient cryogenic storage and operation. It covers the main vacuum production systems and their role in insulation, alongside the properties of cryogenic fluids, storage techniques, and key applications such as cryotherapy, superconductivity, propulsion, and food preservation, while addressing practical challenges related to energy consumption, insulation losses, and safety in modern engineering systems.
Course III: It focuses on the separation, purification, and liquefaction processes of cryogenic fluids, introducing the concept of the ideal separation system and industrial techniques such as cryogenic rectification. It explains the role and operation of the Joule–Thomson valve in gas expansion and cooling, with particular emphasis on air separation processes for the production of industrial gases. The chapter also covers the main liquefaction methods of permanent gases, including the Linde–Hampson process, its double-compression variant, and the Claude process, highlighting their principles and engineering applications in cryogenic systems.
