Abstract
This numerical work developed and analyzed a HVAC system, based on horizontal confluents jets system, in summer typical day conditions placed in a virtual office chamber. Presents and applies a numerical model, developed by the authors in the last years, that considers the coupling of the CFD and HTR. In the input data are used the Computer Aided Design geometry, the location of the occupants and the external environmental variables, while the occupants’ geometry is generated by empirical equations, based in height and weight. Above the head level, six air ducts, connected to the ceiling area, compose the exhaust system. The inlet system was based on four vertical ducts with 0.15 m diameter, located on the corner of the office chamber, are equipped with consecutive holes who promotes horizontal jets near the wall. The thermal comfort, the indoor air quality, the Draught Risk, the effectiveness for heat removal, the effectiveness for contaminant removal and the ADI are evaluated.
