Parking (Car park) Ventilation by Jet Fan

Construction and operation of commercial and office complexes are highly booming, according to the optimal use of existing spaces in major cities. Due to the compression of space in such complexes, parking’s are designed with the assumption to use the most space possible. Large numbers of cars in the car park and enclosed spaces, it will be certainly necessary to design a very powerful ventilation system.

The design and implementation of a ventilation system are necessary for enclosed parking and car parks, because of vehicle density. During the normal operation in a car park, vehicles produce pollutant gases like carbon monoxide and NOx which could cause serious damages to people inside the parking lot. There is also another risk in car parks, which is the possibility of fire. Considering the enclosed area inside the parking’s, Incidence of fire will produce deadly gases and a huge amount of smoke. According to this situation, parking ventilation systems must have the capability to control the smoke and deadly gases and provide the required time for people to escape from danger.

The old method for parking ventilation was using ventilation ducts in the roof. This method cause many limits in design and operation and in a fire situation, ventilation was not good enough.

New technology in this field is the application of jet fan for normal ventilation and smoke extraction in case of fire in parking’s. In fact, this technology represents the most innovative and cost-effective alternative to traditional ducted mechanical extraction systems. Carefully managing the project in all its development stages, which requires the fundamental use of fluid dynamics calculation programs - CFD - and also ensures that the system is working correctly. The jet Fan system provides either normal ventilation and can also be provided for smoke extract in case of fire in the parking lot.

After the final design, the performance of jet fan can be evaluated using CFD in normal operation. Also by using PyroSim and FDS software the function of the installed jet fan could be tested during a simulated fire.

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 software to simulate the fire reaction in different environments like Building, parking lot, Car park, Subway, Tunnel, Cinema, Commercial office complex and …

Using PyroSim we could define smoke detectors and sprinklers in the 3D model, to examine the current design in case of fire with both software.

About CFD Simulation

CFD(Computational fluid dynamics) is a branch of fluid mechanics that uses numerical methods to solve and analyze fluid behavior.
During a CFD simulation, the computer calculates the interaction of liquids and gases with boundary conditions in small cells. These cells will form the computational domain in which the simulation takes place. Initial and boundary conditions shall be defined, according to each case. 
Ongoing research yields software that improves complex simulation scenarios such as turbulent flow accuracy and speed. 
We use CFD simulation for many projects, like ventilation, aerodynamics, pumps and turbines, and other industrial uses. Generally, CFD simulations help designers achieve better results and can reduce the cost of production. 
For example, in ventilation cases, CFD can show us the stream of air that circulates in a room or parking lot. In such circumstances, we can also calculate the temperature, pressure, and flow speed at any point of the computational domain.

We usualy recommend use CFD to check the design of industrial ventilation for a parking lot, warehouses, factories and workshops using a Jet fan or axial fans.

Tunnel ventilation and Industrial ventilation

In recent years contemporaneous with the advancement of technology, special consideration needs to transport infrastructure have been raised. One of the main methods of transportation is road and rail transportation. The main feature of these methods is their generality, which requires special attention to the design details.
One of the most important aspects of road tunnels is ventilation. Tunnel ventilation has a direct impact on car passengers' health. So tunnel ventilation could be designed using Jet-fans or other ventilation methods. We have good experience in tunnel ventilation design, using jet-fan(longitudinal tunnel ventilation method). We can handle tunnel ventilation design projects in the middle east(Iraq, Kuwait, Oman, UAE, and KSA)
We can also handle tunnel ventilation simulation(CFD) and fire and smoke simulation in tunnels(PyroSim, FDS)

Design and Simulation of road and rail tunnel ventilation

The new drilling techniques and TBM devices have led to the possibility of digging long tunnels in less time than usual. One of the requirements for digging long tunnels is proper ventilation. The most common method of urban tunnels ventilation is the longitudinal ventilation using jet fans.
To cause proper and healthy ventilation in tunnels, additional to equipment, correctly design and detailed calculations of pollutants and environmental conditions are needed.
To carry out tunnel ventilation computing feasibility studies, some processes must be performed regularly and with a particular order. To basic acquaintance with tunnel ventilation calculation process, the main steps of the process, will be mentioned as followed:

• Finding out technical drawings and geographical position of the tunnel

• Studying the Climatic traffic characteristics of the region and view

• Studying the status of pollutants produced by vehicles and analysis of traffic statistics

• Calculations to determine the required flow rate for ventilation in traffic and fire mode

• Studying different methods of ventilation and selection of the appropriate method

• Flow simulation inside tunnels with Fluent, SES and flow works software

• Figuring out all ventilation equipment on the chosen method, along with Technical Specification

Araco by having the suitable knowledge, work experience in the field of tunnel ventilation and utilizing Finite element flow simulation techniques is present to carry out projects in road and rail tunnel ventilation design with high certitude and quality.

Design and simulation of industrial ventilation and local ventilation - CFD

Improved ventilation and sanitary conditions inside the silo and factories in addition to raising the efficiency of labors play a fundamental role in reducing the damage caused by pollutants, the equipment inside the workshop and the factory. In fact, the purpose of the 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 Aviculture. 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 a Jet fan or axial fans reviews of the professionals must be used, not just dealers. However, after simulations of airflow inside the enclosure, the resulting data to be matched with the nearest weather station information.

 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.
