Car park ventilation systems consist of jet fans, panels that keep these fans under control and circuit control systems. Jet fans work by pushing air masses through the discharge opening thanks to the high air speed that occurs.
Jet fans strategically placed throughout the park area remove harmful daily exhaust gases and, in the event of a fire, direct the smoke toward the shafts, allowing people time to escape.
Axial fans are manufactured in accordance with ISO 9001 standards. They are systems suitable for installation inside or outside the fire zone, at standard temperature or 300 degrees, with flow and static pressure determined according to project standards.
How to Install Car Park Ventilation Systems?
Ventilation systems , which are mandatory in indoor parking lots, are installed in a way that is visible to the eye. Therefore, they must have an aesthetic appearance that is pleasing to the eye.
Oval
Octagonal
Banana
Round
Radial shape options are available.
In order to install the most suitable ventilation system for the indoor parking lot, an expert team carries out a survey, evaluates the system and presents you with the most suitable ventilation system.
How to Implement Project Design?
Since car parks are closed areas, the amount of gas emitted by cars increases during the day. Therefore, in car parks that will be mechanically ventilated, harmful gases and dust should be removed, fresh air should be provided and all parking floors should be ventilated in the same way.
Accordingly;
Fan locations and parking area fan layout drawings are created.
Working procedures and diagrams of the fans are drawn.
All electrical and connection diagrams to be found on the control panels are created.
Fan room installation and drawings are carried out.
For the project, it is considered that the smoke evacuation system and fire hazard will start from the upper floors, and therefore the project design is carried out by determining the smoke flow rates accordingly.
How to Perform a Ventilation Cold Smoke Test?
Jet fan systems used in parking lot ventilation systems must operate efficiently. Thus, maintenance can be easily done at certain intervals and their longevity is ensured.
During the control of the system;
Jet fans
Jet fan system panel
Main axial exhaust and fresh air fans located on the shafts
Care is taken to ensure that the shaft dampers and bypass dampers are connected correctly.
Thanks to the cold smoke test, the commissioning of the system is completed.
What are the Ceiling Features in Car Park Ventilation Systems?
In the ventilation systems designed for the car park, supply and exhaust points are determined and a system that complements the natural air path and circulates the car park effectively is selected.
To make the system more active, jet fans are placed in line with the supporting ceiling beams. If this is not possible, the possibility of the system operating efficiently and effectively is reduced and the need for more fans arises.
If sufficient vertical space is available, fans can also be flush mounted between ceiling joists to minimise system height, whilst providing maximum flexibility in system design.
How Are Exhaust Rates Calculated?
Supply air flows should be between 75% and 90% of the exhaust air volume. This ratio is based on the parking lot pressure, which should be at most 12Pa. When calculating, the area or level area is taken in square meters. At the same time; factors such as parking lot usage factor, vehicle type factor, personnel usage are also taken into account.
What is the Sound Emission Level in the System to be Installed?
Indoor car parks are one of the places with the highest noise sources. The biggest source of this noise is cars. Due to the moving cars, the sound pressure level inside the car park is approximately 75 dB(A).
In addition, there are other noise sources in parking lots. Ventilation systems are also noise sources in parking lots. Jet fans used in parking lot ventilation systems produce 45-61 dB(A) per fan, depending on the type and size.
