• Thermal Power Engineering, Semester 2, position 2

Achieving of competence and academic skills as well as methods for their acquisition. The development of creative abilities and practical skills which are essential to the profession. Objectives are concrete and achievable and in full accordance with the defined basic tasks and objectives of the study program.

Student acquires subject-specific abilities that are essential for the quality of professional activities: analysis, synthesis and prediction of solutions and consequences; application of knowledge in practice; linking the basic knowledge in various fields with their application to solve specific problems.

Thermodynamic basis: Moist air, thermodynamic properties of moist air, Mollier's "h-x" diagram, Important psychometric processes, Dalton's and Lewis's Law of evaporation, Wet bulb temperature of moist air, Evaporation heat transfer calculation, Merkel's coefficient; Heat exchangers: NTU method, Heat exchanger characteristics; Characteristics of compressors; Condensers: Sizing of air-cooled, water-cooled and evaporative condensers; Evaporators: the process of refrigerant boiling, the processes on the cooled fluid side, Sizing of air cooling evaporators, Characteristics of evaporators; Analysis of complete vapour compression refrigeration systems.

Auditory training: Psychometric processes, Evaporation heat transfer; prediction of the compressor characteristic, sizing of condensers (air-cooled, water-cooled and evaporative), sizing of evaporators, evaporator characteristic calculation; Analysis of complete vapour compression refrigeration systems; Laboratory exercise: demonstration of the installation in an industrial refrigeration plant; Design project of refrigeration system: work in groups of 5 students (for a particular object and refrigerant), calculation and selection of elements of refrigeration plants, PI diagram of refrigeration plant.
