Abstract: This numerical work develops a HVAC system, based in a ceiling mounted localized air distribution system. This work presents and applies a numerical model that considers the coupling of the Computer Fluid Dynamics and Human Thermal Response. The coupling system, itself, generates all equations and space geometry and occupation presence and transfers the inputs/output between the Computer Fluid Dynamics and Human Thermal Response numerical models. The study is made in a virtual chamber occupied by twenty-four virtual occupants and twenty-four seats and equipped with a new ceiling mounted localized air distribution system. The inlet airflow and the outlet is located above the head levels. In the present study the thermal comfort level, the air quality level, the effectiveness and the ADI are calculated, in winter conditions. In accordance with the obtained results the ADI index increase slightly when the inlet air velocity increase.
Keywords: Human Thermal Response, CFD, ADI, Heat Exchange between the Human and the Environment.
