VENTOS is meant for designers to calculate natural ventilation. The program is mainly suitable for industrial facilities in which, as a result of a manufacturing process, a significant thermal load is created. Then a thermal current generated by a heat source in industrial facilities is a sufficient “driving force” behind ventilation which gusts of wind are not able to disturb.
Input data for the program consists of thermal load, parameters of inlet and outlet vents as well as of mechanical ventilation devices installed in them. The program calculates the maximum temperature under the roof, the quantity and speed of air flowing through each vent as well as pressure levelling in the building. The program allows for taking into account mechanical ventilation and wind effects.
VENTOS operates in three languages: Polish, English, and German. It is able to produce a report with all numerical data and a diagrammatic drawing of the building in each of those three languages. The program can be run, for instance, in the Polish language and then a report in another language can be printed additionally.
