Study of the energetic performance of a personalized ventilation system

摘要

The personalized ventilation system aims to improve the quality of the inhaled air, to diminue the risk of transmission of the infectious agents and to improve the thermal comfort of the occupants . The principle of this work is to compare the classical ventilation system and the personalized ventilation system from the energy consumption and the thermal comfort point of view. The analyse was made with a nodal model, using the numerical simulations in the SPARK simulation environment. The object of the simulations was a classroom in Bucharest, Romania. The result showed that personalized ventilation can reduce the energy consumption of about 49% and to provide the desired thermal comfort.
