The course introduces the fundamental elements for the knowledge climatization and heating plants and the correct planning of the same, referrring with to the technical-economic aspects too.
At the end of the module the students will have acquired the knowledge of the fundamental aspects related to the design of air conditioning civil plants in buildings and to the use of use of multi-energy systems in accordance with current legislation.
These objectives will be achieved with theoretical lessons combined with numerical applications carried out during the exercises and the latter representing engineering scenarios present in the activity of the mechanical engineer.
From the hierarchical point of view learning starting from a scale of basic complexity (remembering, understanding) and it will move towards higher complexities such as solving, judging and proposing engineering solutions.
The course consists of lectures and practical applications.
