Abstract


In this paper, a proposed Ceiling Personalized Ventilation (CPV) system was numerically exanimated to explain the influence of the proposed system on both of energy demand and thermal human comfort. This system was installed on the ceiling above the occupant zone to make sure that the fresh air supplied directly to the occupant zone. In addition, this system considers the main ventilation system in the investigated room and targeted the occupied zone only with limited working hours. A validated CFD model was used in this examination. The results show that an insulated healthy zone will appear and bounded the area around the occupant by using the proposed CPV system. This zone will enhance the conditions of the occupant environment and protect the working area from the unwanted thermal effects. Also, the results show that using this system will provide a supplied fresh air directly to the occupied area and this will reduce the demand on energy by reducing the load on the cooling coil. Therefore, using this system will improve the local thermal environment and saving more energy.
