- Educational objectives
- The course aims to provide students with the knowledge and skills required for the design of conventional heating and air conditioning systems. Students will acquire competencies related to the criteria for the main components’ design: air distribution terminals, air duct networks, air handling units, heat emission terminals, water distribution networks, heat generators, and refrigeration machines. A further objective of the course is the design of a complete HVAC system. Through this process, students will develop calculation skills, the ability to analyze results, and the capacity to choose appropriate technical solutions.
- Prerequisites
- In order to be able to understand and apply the majority of the techniques described within the Course, students must have notions of mathematical analysis such as techniques of derivation and integration of functions of several variables, differential equations. Furthermore they must have successfully passed the Applied Thermodynamics and Heat Transfer exam and they have to be able to evaluate heat transfer in building walls and the performance of thermal engines. Finally they have to use psychrometric chart for energy calculations. Knowledge of these techniques represents a mandatory prerequisite for students planning to follow this course with profit.
- Teaching methods
- The course is organized as follows: - Lectures on all the subjects of the program; - Exercises in classroom as training for the design part of the exam. - Dedicated sessions for discussion on the various stages of the design process
- Learning verification modality
- The exam is constituted by:
- Design of a thermal system
- an oral test of about 30 minutes.
The design of a thermal system can be developed in small groups of 2-3 students.
The oral test is aimed to determine:
i) the level of theoretical and methodological knowledge of the contents;
ii) the level of expertise in exposing possible technical solutions to problems of sizing of components and systems,
iii) the independence of judgment in proposing the most appropriate approach for each scope.
The oral examinations also aims to verify the student's ability to expose issues proposed by the Commission with property of language, to support a dialectical relationship during discussion and summarize the results of application of the theories studied.
During the oral exam, the design report and scientific publications on the state of the art of the technologies presented in class will also be discussed. - Extended program
