VENTOS EN

VENTOS ONLINE 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. The 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 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 leveling in the building. The program allows for taking into account mechanical ventilation and wind effects.

VENTOS ONLINE 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.

Formulas in this program are created to determine equilibrium between all thermal gains produced by industrial processes within a building as well as air flow exhausted by the ventilation system. Based on this principle, the program is not intended to calculate air exhaust used to prevent thermodynamic disasters such as fires or an explosion blast in the case of accidental discharge of flammable gases. This program requires the user to possess and apply engineering knowledge and to understand physical phenomena occurring in the natural ventilation of buildings. The results of the program’s calculations will always correspond to the adopted criteria and the input data which have been entered, for which only the user is responsible.
