Subject aims expressed by acquired skills and competences

- student will be able to categorize types of energy and energy resources - to differentiate heating gases according to properties, to value combustibles, evaluate interchangeability - to categorize technological kinds of energy - to evaluate energy and exergy balances - to characterise principles of pumps, compressors, steam cycles, gas turbines, cooling equipment

Teaching methods



The course focuses on the types of energy, resources and energy conversion. Attention is paid to gaseous fuels, the issue of interchangeability of fuel gases, fuel pricing, standardization of energy consumption. Discussed are energy and exergy balances, technology types of energy and energy-related equipment: pumping water, production of compressed air, steam-engine equipment, refrigeration equipment.
