Summary

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.
