OVERVIEW

In the wider framework of energy efficiency and buildings’ performance, the working principles and features of heating, refrigerating, ventilation and air conditioning systems will be illustrated. 
The fundamentals of the physical behavior of buildings will be recap.
Heat pumps will be introduced and their typical sources discussed.
The usage of solar energy through solar collectors and photovoltaic panels will be shown.
Some examples of plant design will be given.

AIMS AND CONTENT

LEARNING OUTCOMES

The course offers a theoretical part and a practical part with general applications. The aim is to provide the basic knowledge for the design of air conditioning systems, with particular reference to those based on the use of energy from renewable sources.

AIMS AND LEARNING OUTCOMES

At the end of the teaching, students must:

• know the fundamentals of the thermo-physical behavior of buildings;
• know the main characteristics of the air conditioning systems:
• know the main characteristics of heat pumps;
• know the fundamentals of solar collectors;
• know the fundamentals of photovoltaic panels;
• be able to perform a first evaluation of the performance of these building' systems;
• solve simple problems of system’s sizing.

PREREQUISITES

Students have to know properly and deeply the main topics and means given by the teachings of Applied Physics and Mathematics.

TEACHING METHODS

The teaching consists of both theoretical lectures and applied lessons. The first ones introduce the main topics, the latter deepen the knowledge and give examples of applications.

SYLLABUS/CONTENT

Air conditioning. HVAC systems.
Heat pumps.
Energy sources of HPs.
Renewable energies. Solar energy: flat solar collectors, photovoltaic panels.
Energy need of buildings.
Plant design examples.

EXAMS

EXAM DESCRIPTION

The exam consists of two mandatory parts: a written test and a subsequent oral test. The written test lasts one hour and a quarter and consists of an open question and an exercise, which can be on theoretical and applicative topics. The test is meant to check if the student has/has not reached a minimum level of knowledge on the main topics. If the outcome of the written test is sufficient, the student is admitted to the oral test, which is also on both theoretical and applicative topics. The oral exam is meant to evaluate to which extent the student is able to analyze, describe and discuss the teaching’s topics. If the oral test is not sufficient, the exam is not passed and the written test must be repeated. Booking to the exam session is via the Unige portal.

To take the exam, it is necessary that the student has completed the online registration and brings his/her identification document. Students who are not registered cannot take the exam.

Exam registrations close at 24:00 on the Saturday preceding the Tuesday exam session. For fairness and to avoid negative impact on the organization of the session, registered students who no longer intend to take the exam must remove themselves from the list by the same deadline mentioned above. Unexcused absences will prevent participation in the next exam session.

ASSESSMENT METHODS

The written test evaluates the successful comprehension of the different topics of the course and the consequent ability to apply the concepts acquired to the solution of some simple problems.
The oral test allows to investigate with more accuracy the student's level of knowledge of the theoretical and applicative themes as well as his/her ability in performing critical reasoning. In the oral examination, attention is also paid to the clarity of the exposition and to the mastery of specific technical language.

FURTHER INFORMATION

To join the exam, the Student must show the University ID and/or other identity document.
During the written test students are allowed to use only a black or blue ballpoint pen, the necessary to erase, a ruler, the calculator. Any needed table / diagram will be supplied within the written test. The usage of handouts, forms or sheets other than those provided is forbidden (exception is made for DSA students).
All the news concerning the teaching (e.g., advices, recommendations, changes to the office hours for students, evaluations of the written tests, etc.) are always posted on the Aulaweb webpage.
Students are advised to update their e-mail address provided by the University with the address of a frequently-checked inbox, so as to receive any urgent notices communicated by the teacher.
