The course, which is part of the "Rational use of energy and Thermal system design" curriculum, aims at providing the principles and techniques required to develop the design of a Heating, Ventilating, and Air Conditioning (HVAC) system serving a residential, tertiary or industrial building, and of its mechanical components. The course is oriented towards practical applications and includes a design exercise concerning the HVAC system of a tertiary building.

The course consists of theory lectures and practical sessions on the quantitative aspects of HVAC system design. Students will also particpato to instruction visits to systems that represent the state of the art from the point of view of typologies and technical solutions. Students are asked to develop, in groups of 2-3, a practical design assignment concerning the HVAC system of a tertiary building. The practice includes the definition of the design data, the calculation of the heating and cooling loads, the selection of system typologies, the sizing of the fluid distribution networks, the selection of the main system components, and the development of the block diagram / functional scheme of the system. The final product of the assignment includes the calculation report and the graphical representation of the system (plans and sections in a suitable scale, block diagram of the system).

Modalitŕ di esame: prova scritta; prova orale obbligatoria; progetto di gruppo;
The final exam consists of two parts: • Individual, 2 hours open-book written test, which consists of the solution of a numerical exercise and the comment to the block diagram of a technical system; each of the above questions are graded on a 1-30 scale. In this test, the student should demonstrate both the ability to rapidly set up and develop a simple system sizing calculation, and the ability to understand the structure and operational logics of a technical system, through the interpretation of its block diagram. • Group oral exam, approximately 30 minutes long, in which the entire group illustrates in detail the practical design exercise developed. At the end of the discussion, the practice receives a grade on a 1-30 scale; all students in the group receive the same grade. In this part of the exam, students should demonstrate their ability to apply all the knowledge and abilities listed in the EXPECTED LEARNING section. There are no temporal constraints in the sequence of the written and oral parts of the exam. The final grade is calculated as the weighted average of each individual part, applying the following percentages: • Exercise (written test): 20% • Schematic diagram (written test): 30% • Practice (oral): 50%
