The course consists of four main topics: Thermodynamics, Heat Transfer, Acoustics and Illumination design. The basic theoretical knowledge is provided together with examples, exercises and analysis of practical cases.
THERMODYNAMICS
Foundations of Thermodynamics. Mass, energy and entropy balance equations. Work, heat and bulk flow interactions. Thermophysical properties of pure substances. Perfect-gas. Heat engines, heat pumps and refrigeration units, thermal efficiency and coefficient of performance. Thermophysical properties of moist air. Psychrometric chart. Dew-point temperature
Applied Thermodynamics. Examples and exercises about components for the treatment of moist air, heating and air conditioning of buildings.
HEAT TRANSFER
Conduction. Steady heat conduction for one dimensional problems with or without heat generation. Thermal-electrical analogy. Critical thickness of insulation. Brief notes on thermal bridges. Brief notes on unsteady heat conduction.
Radiation. Electromagnetic spectrum. Definitions of emittance, irradiance and radiosity. Properties of absorption, reflection and transmission of a surface. The black body radiation, the Planck law and the Stefan-Boltzmann law. Definitions of gray body approximation and of emissivity. Linear approximation of radiation heat transfer and radiation heat transfer coefficient.
Convection. Definition of convective heat transfer coefficient. Foundations of forced convection and free convection.
Buildings applications. Heat transfer through transparent and opaque walls. Thermophysical properties of walls. Estimation of thermal losses and loads and brief notes on some technical standards Brief notes on thermal bridges estimation.
ACOUSTICS
Basic concepts. Sound pressure levels. Reverberation time. Sound reduction index of horizontal and vertical partitions. Façade sound insulation. Sound insulation composition of opaque and transparent elements. Italian legislation: sound insulation of buildings - acoustic requirements.
ILLUMINATION DESIGN
