• Semester 5, position 5

Going through the thermodynamic analysis, students should gain a basic theoretical and professional knowledge about devices and facilities that are used in area of thermo-technique, thermo-energetic and processes engereering, as well as to gain knowledge of the physical phenomena that take place with the processes in steam turbines, gas turbines, refrigeration systems, systems for drying different materials and air conditioning systems.

After successful completion of this course students should be able to: 1) express the First and the Second law of thermodynamics (energy balance and the balance of entropy) for open thermodynamic system 2) express basic characteristic, explain the behavior of the "moist air" in thermomechanical changes of its state (heating, cooling, mixing, wetting, compressing, damping) 3) identify, describe operating principles from the aspect the First law of thermodynamics calculate the energy balance and in terms of the Second law to calculate the balance of entropy and quantify the effects of irreversibility of the process of which happen in particular thermomechanical devices (heat exchanges, the boiler, turbine, pump, compressor, fan, valve, uninstalled channels and pipes) 4) identify, describe and from the aspects of energy flows explain operating principles of moderately complex thermomechanical plant, (gas-fired power plants, steam power plants, refrigeration plant, heat pump, air conditioning systems and facilities for convective drying of materials) 5) calculate the energy and the entropy balance for moderately complex thermomechanical plants by applying the First and the Second law of thermodynamics for open systems 6) analyzes and with arguments link energetic and entropic quality of work moderately complex thermomechanical plants
