CAR PARK VENTILATION SYSTEMS
Optimizing Car Park Ventilation through CFD Analysis with Flowpak
The use of Computational Fluid Dynamics (CFD) for the analysis and design of carpark ventilation systems is a crucial step in ensuring compliance with Qatar Civil Defense regulations.
The main advantage of using CFD is assessing the ventilation system’s performance before installation, providing confidence to all parties early in the project.
At Flowpak, our team of experts utilises state-of-the-art CFD software, such as ANSYS CFX, to analyse and evaluate the airflow patterns, visibility and temperature distribution in the carpark. This allows us to identify potential areas of improvement in the ventilation design and make necessary adjustments before installation.
By utilising CFD in the design phase, it is much easier and cost-effective to agree on expectations and correct any problems, as opposed to discovering them after testing upon completion of the installation.
Flowpak’s CFD Analysis Solutions for Optimizing Ventilation and AC in Souq Waqif Underground Car Park
Flowpak, a specialised consulting firm in ventilation and air conditioning systems, helped design and implement a successful combination of car park ventilation and air conditioning systems in the underground car park of Souk Wakif. Using CFD simulation, the team identified potential areas of improvement in the design to meet the safety and regulatory requirements of Qatar Civil Defense for underground car parks. The result was a design that met safety standards and provided a comfortable environment for the car park occupants.
King Fahd University Car Park: Optimizing Ventilation Design with Flowpak’s CFD Analysis
Flowpak provided CFD simulation for the King Fahd University Car Park project in Saudi Arabia, helping the designer meet the local civil defence criteria.
The team quickly adapted to local regulations and standards, identifying potential areas of improvement in the ventilation design. The simulation results optimised the design, ensuring the systems effectively controlled smoke and maintained safe visibility and temperatures during a fire.
Ensuring Compliance with Qatar Civil Defense Standards for Car Park Smoke Control and Ventilation System with Flowpak
The Qatar Civil Defense has set requirements for designing and operating smoke control and ventilation systems in enclosed or underground car parks with more than 2000 square meters of floor area.
These systems, which can be either conventional mechanical smoke extract systems or smoke purging systems, shall be designed to maintain smoke layers at the height of at least 1.8 meters from the floor, contain the smoke within a 1000 square meter area from the centre of the fire, and be independent of other building systems.
The systems shall also have a minimum exhaust rate of 6 air changes per hour for general ventilation and 10 air changes per hour under the smoke mode and be designed in accordance with NFPA 88A and ASHRAE Handbook.
The use of impulse ventilation or jet/thrust fans assisted car park smoke exhaust ventilation systems must be confirmed through a performance-based design approach and CFD fire modelling.
