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

Heating systems and equipment: heat exchangers, boilers, furnaces, solar thermal collectors. District heating and cogeneration. Refrigeration: vapour compression, absorption and adsorption systems and components. Cooling towers, evaporative condensers and desiccant wheels. Thermal energy storage systems: sensible energy (hot water tanks, thermoactive enclosures, etc.), latent thermal energy (thermal energy storage materials), thermochemical energy (hints).
Exergy analysis of heating, refrigeration and thermal storage equipment.
Thermoeconomics analysis. Concepts from graph theory and matrix algebra. Thermoeconomic approach to Energy Audits, Diagnosis of Thermal System Operation and Design of Thermal Systems. Cost accounting and exergy. Exergy cost theory. Other methods of cost allocations. Supply-driven (FP) and demand-driven (PF) model. Thermoeconomic dyagnosis.
Exergy methodologies for the analysis of sustainability.

Teaching methods

Instruction is in the form of lectures and exercises.

Assessment methods

Assessment is individual and based oral examinations consisting of a numerical problem and two questions pertaining on the subjects discussed during the lectures.
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.
Grades
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
