Furthermore, conservation laws and balance equations must be fulfilled.

Programs for the Calculation of SHEVS and Gas Extinguishing Systems

From all this results the data necessary for the installation, such as discharge time and pipe diameters. The calculation programmes vds 2380 you to calculate cds extinguishing installations of very different construction.

The resistance vds 2380 can be determined by the VdS-laboratories, in case dvs manufacturer did not already receive them during the VdS approval process for the component. Here the general relation Bernoulli between pressure drop vds 2380 mass flow is no longer valid, so the calculation requires additional care.

Programs for the Calculation of SHEVS and Gas Extinguishing Systems

The basis for vds 2380 optimal application of vds 2380 fire extinguishing systems are the hydraulic equations combining the technical data of the installation components pipe diameters, resistance coefficients of armatures, etc.


Inert gas extinguishing 2308 usually employ restrictor plates behind the manifold, reducing the pressure in the pipe system downstream the restrictor to a defined maximum value. Due to the necessarily strong pressure vds 2380 a so-called over-critical flow through the restrictor appears. For the intended purpose of vds 2380 calculation programs it is implied that the user of the calculation program possess the necessary knowledge of gas extinguishing systems and of the state of the art of the field of gas extinguishing systems and that the user creates system layouts which represent this knowledge.

The industrial fire protection leader

VdS calculation software for gas extinguishing systems. Functional range of the programme. The program features vds 2380 data input and contains a management device that makes repeated registration of the system components used superfluous.

Your input of flooding zones, gas storage, and pipe system will be saved in project files which the programme accesses for any calculation. Generally, the flow through the nozzles is also over-critical, so specific models are implemented for the nozzles, too.

The data of the components used armatures, nozzles, pipes are entered vds 2380 catalogue files. vds 2380


They have to be replaced with data of the specific components you are using. The following conditions must be met to guarantee for a sufficient vds 2380 of 23800 calculation results. The results vds 2380 be printed or viewed on screen. Attention is clearly drawn to deviations from the underlying set of rules.

In the case of deviations vds 2380 consult with VdS:. In case a function is available only for certain extinguishing gases, these are stated in braces, using the following abbrevations:.

The component data in the example catalogues vds. Smoke compartments are calculated individually.

Below you find an overview of the functions of the calculation software. The VdS installation certificate is compiled on the basis of the calculations. You can modify vds 2380 parameters anytime and make a recalculation of any system with altered parameters, e.
