Learning Outcomes : The course is a specialization course on industrial refrigeration systems for both food preservation and freezing, as well as for drug preservation. Additionally, due to the expertise and laboratory facilities, open and closed-type refrigeration systems with liquid and solid adsorbent materials are analyzed and examined in combination with innovative solar thermal systems and thermal storage devices. The course material aims to introduce students to the components of refrigeration plants, their connection with industrial food preservation and freezing plants, as well as with refrigerant leaks identified in such plants. At the same time, within the framework of the course, students have the opportunity to understand other refrigeration systems used in the pharmaceutical industry and for dehumidification, heating, and cooling of large installations, aiming at the use of other environmentally friendly working fluids. Sizing of such applications and the possibility of integrating renewable energy sources, such as innovative solar cogeneration systems, are carried out. Additionally, the course aims for the student to understand the latest technological achievements in the field of industrial refrigeration, as well as the possibilities of using innovative refrigeration systems in large installations for dehumidification, heating, and cooling. In this sense, the course is a basic specialization course through which students learn to analyze and size refrigeration systems for industrial plants and large tertiary sector buildings, while through the laboratories offered within the course, they understand ways to improve the energy efficiency of various refrigeration systems. Upon successful completion of the course, the student will be able to: • Understand the components of industrial refrigeration plants. • Use software and methodologies for sizing each component of the refrigeration plant. • Use methodologies for sizing large industrial storage spaces for food preservation and freezing, as well as for drug preservation. • Understand the effects of refrigerant leakage from large installations. • Have knowledge of alternative methods of dehumidification and cooling in combination with renewable energy sources to improve their energy efficiency. • Be able to identify failures in industrial refrigeration plant arrangements. • Collaborate with fellow students during laboratories to check the performance of solar cooling systems, dehumidification with solid adsorbent and liquid absorbent material, as well as simple vapor compression refrigeration systems.
