Abstract
This numerical study, made inside a virtual office, considers a Building Thermal Response software to evaluate the surrounding surfaces, a CFD software to evaluate airflow around the occupants and the indoor air quality and a Human Thermal Response to calculate the occupants’ temperature distribution and the thermal comfort level. This study considers a Heated, Ventilation and Air Conditioning system constituted by an inlet and exhaust systems. The inlet system, based on confluent jets, is built with horizontal ducts, located on the sides of the room, equipped with nozzles to promote vertical jets. The exhaust system is founded on a vertical duct, placed in the ceiling central area. The virtual office is occupied by four persons seated around a table. The Air Diffusion Index (ADI) and Air Diffusion Turbulence Index (ADTI) are calculated for winter typical conditions. The results show that ADI and ADTI improve with increasing inlet air velocity.
