Improved ventilation and sanitary conditions inside the silo and factories in addition to raising the efficiency of labors, plays a fundamental role in reducing the damage caused by pollutants, the equipment inside the workshop and factory. In fact, the purpose of design of industrial ventilation is not necessarily heating and cooling , but also reducing the concentration of pollutants in the environment by removing emissions and getting fresh air.
Environmental pollutants can include different items:
1- Pollutants produced by internal combustion engines such as diesel generators, forklifts and heavy machinery, which are mainly in the form of combinations of carbon and nitrogen and soot in the environment.
2- Chemical contaminants that are generally caused by chemical processes within the production line in many industries, including the production of zinc, steel, acid production, mushroom production and even Avicultures . This type of pollutants in addition to severe injuries to personnel health, cause severe corrosion of equipment.
3- Particulate, this type of contamination is extremely common in the manufacture of cement, steel, fiberglass and rock wool, Woodworking Shops and Coal production workshops. This particulates in the absence of proper ventilation after breathing, causing acute and chronic diseases and at the same time can severely damage the electrical circuits and mechanical equipment.
According to late subjects it is recommended that for the design of industrial ventilation for warehouses, factories and workshops with using Jet fan or axial fans reviews of the professionals must be used, not just dealers. However, after simulations of air flow inside the enclosure, the resulting data to be matched with the nearest weather station information.
Design and Simulation of parking ventilation using jet fans
Construction and operation of commercial and office complex is highly booming, according to the optimal use of existing spaces in major cities.
Due to the compression of space in such complexes , parkings are designed with assumption to use the most space possible. Large numbers of cars in parkings and enclosed spaces, it will be certainly necessary to design a very powerful ventilation system. In such situations, we recommend to use of jet fans for parkings ventilation. At the same time, for the installation of such a ventilation system it must first be carried out to simulate flow rate in the parking .
It should be noted that due to the high cost of this type of ventilation system, design and simulation must be carried out by the consulting companies. Designing by manufacturers and retailers can lead to a sharp increase in project costs.
PyroSim and FDS Simulations
PyroSim is a graphical user interface for the Fire Dynamics Simulator (FDS). PyroSim helps companies to create and manage the details of complex fire models.
PyroSim and FDS are both using as main softwares to simulate the fire reaction in different environments like Building, parking lot, Subway, Tunnel, Cinema, Commercial office complex and …
Meanwhile it is possible to define smoke detectors and sprinklers in 3D model, in order to examine the current design in case of fire with both softwares.
Meanwhile it is possible to link PyroSim results with Pathfinder software which is advanced movement simulation combined with high-quality 3-D animated results, gives reliable answers.
