| The Technical Building Code (CTE) demands a minimal renovation of air to guarantee the quality of the interior air in the residential buildings. The air renovation is realized by the circulation of the air through several ventilation opening (intake, intermediate and exhaust) [1]. The distribution of the air flow and the design of the ventilation system are important factors in order to achieve an effective renovation of the air in the enclosure with the lowest energy cost. Therefore, in this paper the ventilation is analyzed in a typical house distribution which takes place in the majority of the residential buildings, in particular when the bedroom has a bath (exhaust) incorporated inside, being conditioned the exit of the air. In the housing study, the ventilation system is calculated and dimensioned as the CTE dictates. The flows of exhaust calculated in the house are superior to those of intake; therefore a flow balance is necessary to equalize them. In this sense, when the designer balances the air flows of intake to those of exhaust, several options appear which depend on the distribution of the air flow and the redistribution of the air flows of intake. This implies that the air flows in the intake room change and therefore, the size of the ventilation grids also does. Finally, the most representative dimensional options which concern to the bedroom are analyzed. In order to do this, a simulation model, constituted by the geometry of the room, the furniture and three ventilation grids (intake, intermediate and exhaust), has been developed using the program STAR_CCM + of Computational Fluid Dynamics (CFD) [2]. | |
