Types of Ventilation Systems

There are three types of systems that you need to know about, helping you identify which ones you need, how they will benefit you and what options are available for each type of ventilation system available. The three options include smoke, natural and mechanical.

Smoke ventilation systems are designed for stairwells, corridors, smoke shafts and roofs. These systems can be valuable in the event of a fire, enabling everyone to get out of the building with minimal risk of smoke inhalation. We all know that hot air rises and the heat and smoke from a fire will rise and taken out of the ventilation system, enabling those inside the building to quickly find their ways out of the fire exits and to the fire assembly point with minimal risk.

Smoke systems are essential in all types of commercial buildings, agricultural buildings, hospitals, hotels and more. They are the ideal choice for high rise buildings, where people need to escape via their stairs to get to safety. The smoke can be reduced as it is drawn out of the ventilation system, providing ample time to get to safety and wait for the fire department to arrive.

Natural ventilation systems are a top choice of buildings, home and more. They come in a variety of options that you can choose from to find the perfect match based on your specific requirements. The benefit of natural ventilation systems is that they don’t work with motorised fans, which can help you save money in the long run.
The natural solutions are based on the fact that hot air rises and uses ventilation vents to draw out the hot air while cooler and natural air enters the building through windows.

One of the options available is the cross ventilation system. This system requires you have your windows open in your office, the system provides a positive pressure which draws fresh air through windows on one side and then as the air rises it is drawn out of the system on the other.

Stack systems are very popular and also works on warm air rising. These systems have a vacuum at a lower level which sucks fresh air into the building; the hot air is then pushed up, escaping through roof vents. This system is very similar to roof vents, which provide the same service, enabling all the hot air to escape through the roof, helping keep the area cool and reducing the need for your air conditioner to run all day, this can also be a cost effective solution helping you save money in the future.

Passive cooling has grown in popularity with larger buildings throughout the world. During the day the floor gets hot as the hot air gets trapped, during the night when the temperatures drop the building is cooled via vents. This means when you get to work the next day, the building is cool and comfortable.

Mechanical ventilation systems are usually chosen when natural ventilation cannot be used. This normally applies to areas which cannot benefit from a natural air flow, such as an underground parking garage. Mechanical systems come with smoke and ventilation solutions, using mechanical fans to draw out the hot and polluted air and pumping in fresh and clean air from outside.
