| Course abstract | |
| The purpose of the study course: to learn the theoretical foundations of thermodynamics, the principles of heat extraction and conduction. Students learn to calculate the amount of work and heat in thermodynamic processes and cycles, heat losses and supplied energy in heating and cooling equipment. An understanding of the thermodynamic basics of the operation of heating and cooling equipment is developed. Students acquire knowledge and understanding of the types and regularities of heat transfer, acquire basic knowledge of energy resources (fuels) and their main properties, conversion of their chemical energy into thermal energy. | |
