During study course "Thermal energy systems. Basic course ", thermodynamic cycles and processes and the mechanisms of heat propagation are examined.
When viewing a variety of thermodynamic cycles and processes, students learn the foundations of each process, as well as gain knowledge about how this process can be used in a variety of applications.
While examining the mechanisms of heat propagation, the students learn of heat conduction, convection, radiation and transition as well as acquire practical knowledge about how to reduce heat losses, thus enhancing energy efficiency of buildings, heating networks, and other structures, equipment and processes.

To gain knowledge about different thermodynamic processes and cycles, gas state equation, specific heat capacity, enthalpy, entropy, internal energy, external work. Learn to distinguish between different types of heat propagation. Understand and learn to calculate the heat lost due to heat conduction, radiation, convection and heat transfer.

Work with literature on thermodynamic processes and heat transfer. Practical calculations with the help of computer programs such as MS Excel.
