Abstract:

Hybrid ventilation systems present many advantages compared to the natural or mechanical ventilation systems. In thecase of buildings with significant heat gains, they seem to be the proper solution, if correctly analyzed and designed. Thepaper presents the calculations and study of the natural ventilation parameters with the possibility of including roof fans inthe model glasswork in Kielce, Poland. The calculations for the optimization process were conducted using Ventos software.The limitations of the method include maximal values of air temperature at the top of the building, air velocity at the inletsand outlets, and negative pressure. Conclusions for the summer season arise that the most optimal solution ensuring theminimum internal temperature and air velocity conditions for the glassworks building is the use of wall inlets located on twolevels. On the other hand, in winter conditions not all wall intakes should be open. Further analyses and simulations wereperformed for hybrid ventilation. Assessments confirm the accuracy and efficiency of using natural ventilation in facilitieswith significant heat gains, including glassworks.
