B2399 - Heating, Refrigeration and Thermal Storage

Learning outcomes

On completion of this course, the student will be able to describe in detail the components of heating, refrigeration, and thermal storage systems; know which traditional and new-generation heating, refrigeration and thermal storage systems are suitable candidates for industrial, commercial, and residential applications; analyse in terms of Energy balances the heating, refrigeration and thermal storage system both in their components and as a whole; combine the exergetic and economic analysis for the purpose of Energy Audits, Diagnosis of Thermal System Operation or Design of Thermal Systems.

Course contents

Teaching methods

Instruction is in the form of classroom lectures. All subjects are also illustrated through numerical exercises, which are solved during class.

Assessment methods

Attendance of classes is strongly recommended in order to get firm understanding of the subject, yet it is neither compulsory nor significant in the determination of the final grade, as this is solely based on the candidates' performance during theexamination.

Assessment is individual and based oral examinations consisting of a numerical problem and two questions pertaining on the subjects discussed during the lectures. The only allowed material for the solution of the exercise is the pocket calculator; if tables are needed (e.g. thermodynamic tables), these are provided during the test.

If students have a decision from Bologna University entitling them to Targeted Study Support due to a documented disability, the examiner has the right to give such students an adapted examination or to examine them in a different manner.

Successful completion of the course entitles to a grade from 18 (Pass) to 30 with Merit (Distinction); corresponding grades (e.g. Distinction/Pass with some Distinction/Pass) for international students may be awarded upon request.

Teaching tools

Numerical exercises during lectures. Blackboard, PC, projected slides.

All teaching material used in the lessons is made available on the online page of the course through https://virtuale.unibo.it
