Course abstract

During studies, the basic of Thermodynamic are being acquired. Students get skills to calculate the mechanical energy and heat during thermodynamic processes and cycles, heat losses and supply of energy in heat equipment. Students get understanding of thermodynamic basic of heat and cooling equipment. Students get knowledge and understanding in heat transferring ways and regularities.

Learning outcomes and their assessment

• knowledge: the fundamentals of thermodinamics, the balance of heat thermotechnic equipment, the regularities of heat transfer and determination factors, the thermodynamic fundamental of heat equipment operation;
• skills: to make the calculations of heat flow of heat equipment, to make the calculations of heat transfer for different practical application, make the analyse of thermodynamic processes;
• competence: to evaluate the energy flow of the given heat equipment or object, analysis of heat flow formation and basic factors that impact it; choise of heat utilisation solutions.
