There are many different types of ventilation systems, each one suited to a particular type of building and with a specific defined role. The same is true of car park ventilation systems, which offer unique features that make them particularly appropriate for their particular function.
One of the main considerations when it comes to installing this type of system is that it needs to meet one very specific requirement - the safe and timely removal of toxic exhaust fumes that can build up in an area.
In high rise car parks it is often possible to integrate natural ventilation systems due to access to open air that is often built into structures that are to serve this function. For basement and enclosed car parking facilities however, mechanical systems are often required in order to effectively remove exhaust and keep the building within the legal health and safety norms.
It is often more effective to actually design a building to integrate natural ventilation as much as possible in order to reduce the expense of installing a mechanical ventilation system, although it can also be argued that the latter solution can allow for greater usable floor space, which is of great importance when it comes to car parks.
Two of the main features of mechanical car park ventilation are the induction fans and impulse jets that are necessary to remove large volumes of air and gases from the building. These two elements work to move the air towards smoke shafts, which will then expel air to the exterior of the building.
These are some of the more recent technological developments that have been proposed for car park ventilation; previous models often relied on extensive ducting throughout the building in order to complete this necessary task.
Although efficient enough to meet the required healthy and safety standards, the presence of the ducting can have a knock on effective on the commercial returns that a car park can benefit from; an extensive amount of it means that a great deal more space is taken up, reducing the number of levels that can be placed in the structure.
Car park ventilation may also bring a number of great benefits to fire fighters in the event of a fire in building or where smoke needs to be cleared after a fire has been extinguished. One of these is the fact that a system such as this can limit the spread of smoke throughout the building due it its efficiency at displacing air in great volumes on a regular basis.
The system also works by enhancing any other smoke ventilation systems already in place, the two working in tandem to remove the smoke resulting from a fire as rapidly as possible. This makes mechanical car park ventilation a great solution in many cases due to its added safety advantages.
In all instances, however, professionals recognise that each building is unique and will require a different number of features and a tailored installation to be effective at what it is supposed to do. Due to this, car park ventilation systems can vary enormously depending on the structure itself and the company hired to find the ideal solution for the building.
During the design and installation of a system, certain regulations must also be respected, depending on whether natural or mechanical ventilation is used. In the case of the latter, it is necessary to provide six air changes per hour in normal conditions to remove exhaust and other gases; this rises to ten air changes per hour in the case of a fire.
The structure of the building, the technology supplied by the installation company and regulation will all therefore have an impact on the final set-up installed in a parking area, to ensure the health and safety of users of the building in regular circumstances as well as in emergency situations.
