After successful completion of the course, students are able to...

• understand and describe the most common applications and functions of cooling and heat pumping technologies,
• design and integrate systems for selected applications in industry, commercial and building applications,
• describe the various cycle processes for the generation of "cold" in refrigeration technologies and "heat" in heat pumps from mechanical energy or heat and calculate thermodynamic parameters (EES or COP),
• describe the function of compressors, heat exchangers, piping, and fittings in the refrigeration cycles,
• read and understand state diagrams for refrigerants and select refrigerants for different applications.

• Description of the thermodynamic cycles of refrigeration systems.
• Discussion of cold steam engines (vapor-compression and absorption refrigeration cycle) and cold gas engines.
• Development of new refrigerants, adaptation to changed environmental creteria.
• Description of the individual components of the refrigeration systems.
• Sizing rules.
• Control technique based problems.
• Applications of refrigeration systems.
