The Study Of Ventilation Calculation And Visualization

Ventilation calculation is needed in both the mechanical ventilation and the natural ventilation. The mathematics modeling of this paper is based on graph theory, technology of ventilation network, object-oriented programing and datebase system. The computer arithmetic of finding loops has been improved. The efficiency of the programme has been enhanced. The stability of Ventilation network calculation has also been improved.Using the object-oriented programing language of Visual C++ as a development tool is the characteristic of this paper. In the operating system of Microsoft Windows, ventilation network calculation and visualization system are established. The result of ventilation network calculation can be display in a more visualizing way with the form of text and graph. At the same time, fan performance curve calculation and visualization are realized. It makes technician more convenient to manage the ventilation system. And technician can manage the fan more intuitionistic. So it has realized the unification of calculation and data management. This has embodied the flexibility of the data change in mining enterprise. Through ventilation network calculation in this system, air natural distribution and air distribution according to need are both realized. In this paper, demonstration are given to show how the system work.
