The lecture "Thermodynamics I" together with the lecture "Chemistry" represents a compulsory module in the Bachelor's degree programs "Mechanical Engineering" and "Energy Technology".
The module teaches the fundamentals of energy balancing in technical systems and deepens this knowledge using practical examples from energy technology. The focus is on the ability to abstract complex systems, divide them into meaningful balance areas, and analyze them correctly in terms of energy.
Students learn to distinguish between different forms of energy and to evaluate them using the concept of entropy. They acquire a sound understanding of states and state variables as well as thermal, caloric, and entropic equations of state for pure substances. Building on this, they learn to apply the first and second laws of thermodynamics with confidence.
Technical examples such as heat engines and simple compression refrigeration cycles are used to deepen theoretical knowledge in a practical way. After completing the module, students will be able to analyze fundamental thermodynamic processes and systematically assess energy relationships in energy technology systems.
