Ventilation fans, or air ventilators, do more than just exchange stale air in your house with fresh air from outdoors – they carry a few important benefits as well when you install them in your space. Ventilation fans can encourage more fresh air intake indoors by efficiently promoting quality air exchange. This will in turn lead to better indoor air quality (IAQ) that can promote better productivity, health and wellbeing for occupants in your house. Ventilation fans also help to save cost for long term comfort – for example, the Energy Recovery Ventilator (ERV) can recover up to 80% of heat energy which generally translates to at least 50% reduction in HVAC costs in general.
Ventilation fans can perform efficiently and come with many significant benefits, but what makes for a successful and optimal ventilation that works for you depends mainly on a few factors that lie with the ventilation fan’s design.
Optimal ventilation is a product of successful factors’ combo
In order for have optimal ventilation to occur, there are a few important contributing factors:
Ventilation fan selection
Getting the right ventilation fan that suits your needs and space will depend on these following sub-factors:
- Fan type: Turbine fans basically work by drawing hot, humid air from the ceiling. As the air enters the fans’ vents, they twist and rotate. As the wind blows, the turbine fins spread out and the motion of the rotating turbine produces a suction force that pulls hot, humid air upwards from the ceiling. Centrifugal fans work by a wheel of blades or impellers that drags air into a circular motion, which is then pushed out of the fan through a centrifugal force created by the rotation and the flow of air changes direction when both exiting and entering the fan.
- Ceiling or wall-mounted location: The exact location to install your ventilation fan will depend on the airflow pattern desired in your space and also the physical characteristics of the building. You will need to survey the building structure and visualize how the air should flow – and thereafter, the place to install the ventilation fan will become evident.
Intake or exhaust hole size
The intake or exhaust hole size can make a difference to mount your ventilation fan – having the right size that suits your ventilation fan model makes it easier to install in your intended space.
Placement of components and usage of accessories
The components in your ventilation fan can help improve efficiency and your space’s air quality. Components such as louvers, dampers, silencers, air filters and so on can be chosen or incorporated into your ventilation fan system to better suit your space needs or requirements – which means that the air ventilation system can be tailored to accommodate your building.
Having known these factors that play an important role in determining optimal function of a ventilation fan, it is easier to understand how to improve your building’s ventilation with ventilation fans.
4 practical tips to improve ventilation with your ventilation fan.
Installing a ventilation fan is the first step to better air quality, but how do you improve the ventilation within your space so that you get more from your ventilation fan? Here are 4 practical tips to follow:
Use the proper ventilation fan model for your space.
The proper ventilation fan model that suits your space – be it in the kitchen, bathroom, laundry room and so on – will be able to draw air more effectively and efficiently. This in turn will work to improve the airflow and create a fresher space without stale air for higher productivity and better wellbeing benefits.
Use proper accessories to help extend the lifespan of ventilation fan.
The proper accessories that complement your ventilation fan can help your ventilation fan to perform better and last longer – therefore saving you energy and costs in the long term.
Change the air filters and keep them clean all the time
Maintaining your ventilation fan is more than just dusting them on the surface; by changing the air filters and keeping them clean at all times not only help to keep your ventilation fan durable, but it is also beneficial for you as you breathe in properly filtered, unpolluted air that is of good quality at all times – preventing you from falling ill when you stay indoors.
Keep the inlet and outlet vents in the same room.
The vents on either inside or outside should be separated in height as much as possible – preferably with the outlet close to the roof and the inlet close to the floor. Ideally, the inlet vent should be on the side of the house that receives the wind or breeze and be in a position that isn’t obscured by an object that might affect the airflow.
In conclusion, you can improve your ventilation at home with an understanding of your ventilation fan’s optimal functions – and benefit from the improvement that comes with it.
