1. Solar Thermal Energy Production in DSF Applied in the Human Comfort Improvements

This work presents a numerical study of solar thermal energy production in DSF applied in the human comfort improvements, in winter conditions. The study considers a solar thermal energy production made in a DSF system placed in the outdoor environment and the improvement of human comfort conditions, namely the thermal comfort and the indoor air quality in a virtual office provided with impinging jets ventilation and occupied by eight occupants seated around the table with eight seats. This study uses a Building Dynamic Response numerical model and coupling of the Computational Fluids Dynamics and Human Thermal Response numerical models. The impinging jets ventilation is built with an inlet system and an outlet system. The inlet system integrates 4 vertical ducts, installed near the corner of the walls, whose airflow direction is descendent, at 0.5 m from the floor. The outlet system integrated six vertical ducts, located above the head level, with ascendant airflow direction. The study considers a solar thermal energy production in DSF during all day and the detailed evaluation of comfort condition in the middle of the morning and afternoon. The indoor air quality, thermal comfort, Draught Risk and Air Distribution Index are evaluated. The results show that the energy production ensures acceptable indoor air quality and thermal comfort conditions.
