Car Park Fire Safety & Ventilation

Car park system solutions should monitor and control pollution and also be ready to jump-into-action during a smoke extraction emergency in the case of a fire.

image

The FläktGroup Thrust Fan System is one of the most efficient and cost effective car park ventilation systems available on the market today.

Both day-to-day pollution and emergency smoke are safely and effectively ventilated. Designed to the highest standards and meeting the most stringent criteria to ensure all design requirements are met.

 

  • High System Performance
  • Low Installation Costs
  • Low Running Costs Optimises Car Park space
  • CFD System Design
  • Complete Turnkey Package available

 

We have built up vast applicational knowledge through involvement in many major construction projects, such as offices, hotels, airports, commercial buildings but also demanding applications like car parks, cruise ships and oil & gas platforms. The ability to offer a full range of products, coupled with our vast experience of HVAC systems, makes FläktGroup the ideal provider of Fire Safety solutions.

Jet Thrust Systems

The FläktGroup Jet Thrust System replaces traditional ductwork with arrays of small fans called Jet Thrust Fans, that distribute the supply air towards the extract point.

 

Higher System Performance

 

By controlling the air supply with Thrust fans a full smoke control design can be made – something just not possible with a conventional ducted extract system. In an emergency situation, full fan extract rate can be reached in as little as 20 seconds allowing immediate response to the situation. Full smoke control can be designed into the system, which can encompass fully reversible Jet and extract fans if required.

 

Lower Installation and Running Costs

 

Installation costs are normally lower with a Thrust Fan System, compared to a ducted system. Installation is simpler saving on labour costs, dependant on the size and form of the car park. There are other hidden savings too. With no ductwork, other services such as, cables, gas and water supplies, soil pipes and so on, can be routed straight across the ceiling line, without having to divert around extract ductwork or hangers. Access for routine maintenance is easy, and of course, there are no distribution ducts and dampers to be cleaned and inspected.

Design & CFD

Jet Thrust Fans are one part of a system, and it doesn’t mater how good the product is if the design is flawed.

 

FläktGroup have a design and CFD Centre of Excellence based in the UK, supported by local specialists .  The Design team are focused on delivering the optimum design  tailored to local regulatory requirements, optimising air quality, fire safety, installed cost and full life cycle costs.

 

We design smoke clearance, smoke control, temperature control and pollution control systems, using the latest techniques.

 

For Consultants:

  • Preserve the integrity of the architects design
  • Reduce project costs by optimising  the system design
  • Reduce energy consumption in ventilation mode

For Contractors:

  • Lower installation costs
  • Simplify installation
  • Optimise other project costs: excavation, smoke shaft size, switchgear

For Building Owners/Operators:

  • Protect life & property
  • Reduce energy consumption
  • Increase lettable space

For Occupants:

  • Increased fire safety
  • Lower noise levels

PART ONE: CAR PARKS: UNDERSTANDING THE NEED FOR VENTILATION

Whether for simple pollution control, smoke clearance or purging, or complete smoke control, almost every car park needs ventilation. Understanding why – and the different purposes ventilation can fulfill – is key to designing and specifying the right system for each car park.

PART TWO: CAR PARKS: THE ADVANTAGES OF A THRUST FAN SYSTEM

While traditional ducted ventilation systems are relatively simple to design and install, they have some inherent disadvantages. A Ductless Jet Thrust System can provide better and more effective airflow, can be made reversible to aid smoke control, and is less likely to reduce vehicle clearance height or car park capacity.

PART THREE: CAR PARKS: POLLUTION CONTROL AND SMOKE CONTROL

Car Park mechanical ventilation systems can be broadly defined into three types: Pollution Only; Smoke Clearance or Purging; and Smoke Control. In this article we look at the characteristics of each type of installation, and how in each case a Jet Thrust System provides a more effective solution than a traditional Ducted System.

PART FOUR: THE BENEFITS OF ENHANCED DESIGN IN CAR PARK VENTILATION SYSTEMS

Enhanced Design involves computer modelling of a project and selecting the best Controls philosophy, depending on the restrictions of the site and the scope of supply. In this article we look at computational fluid dynamics, Advanced Controls, and System benefits.

Introducing the JTv JET THRUST RANGE

Increased Thrust:

  • Fewer fans required can save on fan costs and installation costs
  • Smaller diameters can be used to save on cost and space as well as being easier to install
  • Enhanced safety: Capable of handling larger design fires, where lower thrust fans can’t cope
  • Enhanced smoke control in difficult to ventilate areas
  • Potential to reduce insurance premiums due to increase in fire safety

 

 Increased Efficiency:

  • Lower running costs. Up to 42% less energy used per year
  • Smaller backup power supply requirement, reducing project cost and freeing up space
  • Buildings with lower carbon footprints and reduced energy usage can generate higher rental income as ownership costs are lower


Aerodynamic Hub Design:

  • The JTv uses the radically improved JMv hub design
  • Curved profile enables closer fitting components which reduces losses
