How Should Parking Lot Ventilation Systems Be?

Parking lot ventilation systems; Jet fans consist of panels and circuit control systems that keep these fans under control. Jet fans work by pushing air masses through the discharge mouth, thanks to the high air speed created.

Jet fans strategically placed within the parking area remove daily harmful exhaust gases and, in the event of a fire, direct the smoke towards the shafts, leaving time for people to escape.

Axial fans are produced in accordance with ISO 9001 standards. These are systems suitable for installation inside or outside the fire zone, at a standard temperature of flow and static pressure determined according to project standards or at 300 degrees.

How to Install Car Park Ventilation Systems?

Mandatory installations in indoor parking lots ventilation systemsIt is mounted in a way that is visible to the eye. Therefore, it 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 car park, an expert team carries out a survey, evaluates the system and offers you the most suitable ventilation system.

How to Perform Project Design?

Since parking lots 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 must be removed and fresh air must be provided, and all car park floors must 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 on the control panels are created.

• Fan room installation and drawings are carried out.

It is thought that the smoke evacuation system and fire hazard for the project will start from the upper floors, and therefore the smoke flow rates are determined accordingly and the project design is carried out.

How to Perform Ventilation Cold Smoke Test?

Parking lot ventilation systems The jet fan systems used in it must operate with high performance. Thus, maintenance can be easily carried out at certain periods, ensuring a long life.

During the control of the system;

• jet fans

• Jet fan system panel

• Main axial exhaust and fresh air fans located in the shafts

• Make sure 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 ventilation systems for the parking lot, supply and exhaust points are determined and a system that complements the natural airway and circulates the car park effectively is selected.

To make the system more active, jet fans are placed flush with the supporting ceiling joists. If this is not possible, the probability of the system working efficiently and with performance decreases and the need to use more fans arises.

If there is sufficient vertical space, the highest flexibility is provided in system design; Fans can also be mounted recessed between ceiling joists to minimize the height of the system.

How to Calculate Exhaust Rates?

Supply air flows must be between 75% and 90% of the exhaust air amount. This rate is based on car park pressure, which should be no more than 12Pa. When calculating, the area or level area is taken as square meters. At the same time; Factors such as parking lot usage factor, vehicle type factor and personnel usage are also taken into account.

What is the level of sound emission in the system to be installed?

Indoor parking areas are one of the places with the highest noise source. The biggest source of this noise is cars. The sound pressure level inside the car park is approximately 75 dB(A) due to moving cars.

In addition, there are other sources of noise in parking lots. Ventilation systems are also sources of noise in car parks. Parking lot ventilation systems The jet fans used inside produce 45-61 dB(A) of noise per fan, depending on the type and size.
