Basic calculus knowledge (including multivariable calculus, differentiation and integration of functions)
A final test will assess the learning process results. The final test consists of a written and an oral part. Passing the exam is bound to passing both tests
The written test consists of two exercises, each of which requires to answer three questions (the answers are numerical and must be expressed in the proposed unit of measurement). The written test is sufficient if you answer at least 4 out of 6 questions. If the written test is sufficient, you can access the oral test.
The oral test lasts about 30 minutes and consists of 3-4 questions. During the oral exam, not only the notional knowledge and the simple restitution of what is contained in the lecture notes is checked, but mainly the ability to relate the different topics discussed.
The written test weighs 1/3 while the written test 2/3 of the final mark which is expressed in thirtieths. The minimum threshold is 18/30.
The teaching is partly preparatory, to complete the basic knowledge acquired in the Physics course, and partly formative, introducing the basic knowledge needed to understand the thermo-hygrometric and lighting comfort in the built environment.
At the end of the course, the student will be able to:
Know the laws of thermodynamics and use them in some practical applications,
Know the properties of pure substances
Understand power, heat pump and refrigeration thermodynamic cycles and calculate their efficiency .
Know the basic concepts of thermal comfort in the built environment and the transformations of moist and humid air
Understand heat transfer (conduction, convection and radiation) and correctly set up and deal with the problems in which all forms of heat transfer are involved
Understand the basic knowledge of lighting technology the built environment.
Communicate and express issues related to the subject of the course, hold conversations on issues related to the typical areas of technical physics, and in particular to highlight the relationships between the basic principles and the application aspects
FOUNDATIONS (26 hours) Basic concepts (thermodynamic systems, walls, constraints). Measurement units. First and second law of thermodynamics. Equilibrium for compound systems. Ideal gas model. Polytropic processes. Properties of the matter. Phase equilibrium.
APPLICATIONS (44 hours) Energy conversion processes: quality and degradation of energy. Direct and reversed cycles. Gas and vapour cycles. Psychrometric Applications (humidity, enthalpy, temperature). Fundamentals of heat transfer (conduction, convection, radiation). Windows and solar radiation control.
INSIGHTS (16 hours) Lighting sources and control. Thermal comfort (Fanger approach, adaptive approach, norms). Acoustics (decibel, sound pressure level, equal-loudness contour; weighting filters).
-
Frontal lessons for the whole program. Exercises on some specific topics.
The lessons concerning more theoretical topics are carried out on the blackboard. The lessons that concern most applicative topics are instead carried out with projections.
During some exercise activities, some teaching aids are distributed in the classroom (tables of properties of some substances; psychrometric chart). The same material is however made available on the e-learning platform.
For any need for clarification, contact the teacher who is available for personal meetings (also on the TEAMS platform).
Those who have not been able to take the course are advised to contact the teacher before starting the preparation, in order to schedule an introductory meeting.
