Design and simulation of integral modelling used in thermal acoustic evaluation in occupied spaces

摘要

In this study a design and simulation of integral modelling used in thermal acoustic evaluation in occupied spaces is developed and applied. The study considers a virtual manikin equipped with capacity to evaluate the thermal and the acoustic components. The component of the virtual thermal manikin evaluates the internal airflow around the occupant, the human thermo-physiological and clothing thermal systems and calculates the thermal comfort and the indoor air quality levels. The component of the virtual binaural manikin evaluates the direct and indirect sound and calculates the reverberation time. The space geometry with complex topology is developed using a Computer Aid Design, while the occupants' geometry is made using geometrical equations. The geometry in the surrounding space surfaces and around the occupants' surfaces geometry, is developed by the Computer Aid Design software, is used to calculate the airflow, the radiative heat exchanges and the sound propagation. In this study, performed in an office occupied by eight seated manikins and equipped with confluent jets, the thermal comfort level and the space reverberation time are evaluated and discussed. In accordance with the obtained results the thermal comfort level and the reverberation time are in accordance with the actual standards.
