Thermodynamics

None.

Theoretical lectures with presentation and explanation of the essential part of the subject matters. Students will be encouraged to a deep understand of these issues, using the recommended literature and possibly other books or documents.

Theoretical-practical lectures to solve different problems with discussion of the applications studied. In some theoretical-practical classes are made visits to the laboratories for students to take contact with the most common thermodynamic systems.

In both type of lectures, students are asked about the possible applications of the principles and laws of thermodynamics. Students may obtain approval in tests or in a final exam of the discipline.

The main goal is to give students the basic scientific training in the area of energy systems, preparing them not only to solve problems related to any energy system but also to easily integrate the study of subsequent and related matters.
The knowledge gained in this course will contribute significantly to students to acquire the following specific responsibilities:
– Understand and know how to apply the laws of Thermodynamics and Heat Transfer, including the ability to conduct energetic balances;
– Ability to size, install, operate and maintain HVAC and refrigeration systems;
– Understanding the operation and be able to install, operate and maintain thermal machines in general and in particular internal combustion engines.
