Course description

The aim of the course is to give engineering students a technical-design knowledge related to the field of HVAC systems. Based on the analysis of the interior microclimate and of the thermal and hygrometric loads, the various types of HVAC and the selection criteria are described from an energy and economic point of view for a system optimization. The problems encountered in the design stage and the design methodology of HVAC systems are shown. The students are required to carry out an exercise, aimed at verifying the capacity to design the different types of conditioning systems.


Fluid and thermal sciences


FIRST MODULE (6 ECTS): Properties of moist air and transformations. The thermo-physical properties of building materials : thermal conductivity, vapor permeability , thermal capacity. Technical standards. The thermo-hygrometric verification of building components: vapor diffusion equation, condensation phenomena in building components, verification methods, techniques, protection techniques of components (vapor barrier and thermal insulation). Isolation techniques of building components: diffuse and concentrated isolation, the problems of external, internal and interstitial insulation, in vertical walls and in floors, special types of construction: straight and inverted roof, coat insulation. Bioclimatic architecture: a brief outline of the use of solar energy (solar roofs and ventilated façade), the heat capacity of the buildings. Thermal loads of buildings: the heat losses of the building envelope, thermal bridges, the free contributions, the thermal inertia of buildings, methods of calculation. The verification of building energy consumption: coefficients of thermal dispersion, current regulations. Exercises: project developed during the course concerning the thermal insulation of a building, evaluation of thermal loads and verification of energy consumption by calculation codes.
