Development of a Double Skin Facade System Applied in a Virtual Occupied Chamber

In this study a system constituted by seven double skin facades (DSF), three equipped with venetian blinds and four not blinds, applied in virtual chamber, is developed. The project will be carried out winter conditions, using numerical model, transient based on energy mass balance linear integral equations. equations are used to calculate the air temperature inside DSF blind, inner outer glass, distribution surrounding structure of chamber. These consider convection, conduction, radiation phenomena. heat transfer convection calculated natural, forced, mixed dimensionless coefficients. radiative exchanges, incident solar radiation, absorbed transmitted considered. water concentration contaminants concentration. diffusion work cases studies occupation levels simulated. each case influence ventilation airflow level analyzed. total number thermal indoor quality uncomfortable hours evaluate performance. accordance obtained results, general, acceptable; however, when occupants chamber increases, Predicted Mean Vote index value increases. When rate increases Uncomfortable Hours decreases and, after certain rate, it associated minimum production higher than without system.
