Specific course objectives

The course will provide the cultural basis for the comprehension of the fundamental principles of thermodynamics and heat exchange, in particular of mechanisms of conduction, convention and radiation. By means of numerical exercise the student will be able to apply theoretical lows to the building envelope, aiming to carry out an energetic systems analysis extended to building services as well. At the end of the course the student will have acquired knowledge for the energy certification of a residential unit and its building service performances. In addition theoretical basis on acoustics, natural and artificial lighting will be provide. As a final result the student will have technical knowledge for designing spaces characterized by a good thermal, acoustic and lighting comfort.

Course programme

Thermodynamics
Principles of thermodynamics: general definitions. Reversibility and irreversibility. Work and heat. The principle for closed and open systems, internal energy and enthalpy. II Principle: definitions, entropy. Performance of thermal machines. Carnot cycle. COP of inverse cycle. Thermodynamic diagrams. Ideal gases and their major transformations. Cycles with ideal gas: cycles Otto, Joule and Diesel. Efficiency. Direct and inverse cycles (fluids with liquid-vapor phase transition), heat pump systems.

Heat transfer
Mechanisms of heat transfer. Heat conduction in solids: fundamental law of conduction and its application to flat and cylindrical surfaces in stady-state conditions, thermal insulation and critical thickness of insulation, electrical analogy. Heat transfer in natural and forced convection, finned surfaces. Heat transfer by radiation: definitions, basic laws, black body, gray bodies, electrical analogy. Overall heat transfer coefficient. Heat exchangers and their sizing. Heat transfer in dynamic conditions: calculation methods

Thermodynamics of moist air
Definition of significant parameters: relative and absolute humidity, enthalpy. Mollier diagram for moist air. Transformations on the diagram. Applications and calculations relating to HVAC systems: fundamental thermodynamic processes, mass and energy balances, sensible and latent heat loads, the main systems' configurations. Measuring instruments. The behavior of materials against moisture. Surface and interstitial condensation. Application examples.

Acoustics

Testing and exams

The final verification is represented by a written test and an oral exam (usually the day after the written test) in the dates fixed in the calendar. It is possible to carry an exercise (optional) on the application of concepts. The mode of execution and delivery of the exercise, the access to educational materials are given in the teacher's web page.
