Prerequisites:

Prerequirements for the course are the basic concepts of differential calculus and thermodynamics acquired from the student in the courses of the first year.
It is given for acquired the concepts: energy, power, heat, work, temperature, Carnot's cycle, first law of thermodynamics, perfect gas theory. 
Target skills and knowledge:

The course supplies the engeneering bases with to face the various withins of energy management both on large scale (energy conversion plants) and on small scale (energy requirement of the inhabited structures).
The course presents the main applications to engineering of the Physics course basic concepts (temperature, heat, work etc), the Thermodynamics laws; in particularly will be faced the real thermodynamic cycles (derived from the Carnot's cycle) with attention to the production of electric power and the refrigeration. The course introduces the heat transfer with reference to the applications to the building structures and the heat exchangers used in the conversion plants.
The heat transfer analysis will come moreover finalized to the understanding of the interaction of the human body inside confined system (air conditioning). 
Examination methods:

The examination is based on 2 contextual written tests (that is not separable): a numerical test and a theoretical one with 23 opened questions, final vote in 30th is the sum of the two single tests in 15th. 
Assessment criteria:

The student should demonstrate to master the theoretical learned skills and to know to manage the calculation and design instruments viewed during the course. He should be able to apply the theory to the real engineering cases and in particular to civil applications. 
Course unit contents:

Dimensions and unit systems: fundamental and derived dimensions, International system, Technical system, English system, conversion tables.
