How does A Fan Work?As mentioned, fans work by circulating air around a room. Ventilating the ambient air of a room naturally stimulates the movement of cold and warm air flow. This variation of flow causes an overall lowering of the temperature to provide a sensation of cooling and freshness.
The more volume of air is displaced, the stronger the feeling of cooling. The potential volume of air that can be displaced depends on the size and power of the fan.
It is important to consider that fans, even of a high power, are not able to significantly lower the temperature of a room as well as an air conditioner.
Types of FansTower Fans – are ideal for cramped spaces due to their tall and narrow shape. They are strong and sturdy, capable of strong air output and are favoured for their quiet noise operation.
Desk Fans – are perfect for individual use in the office or at home when quick efficient cooling is required. They can simply be turned on and the refreshing airflow will be noticed immediately.
Pedestal Fans – are larger than desk fans making them better for covering bigger rooms. They consist of a large blade inside a housing unit that sits on top of a stand. Many pedestal fans are height adjustable making them suitable for a wide range of applications.
Floor/Box Fans – are larger than desk fans but smaller than pedestal fans and can cool down rooms of all sizes. Most floor fans will resemble a pedestal fan minus the stand, whereas a box fan is usually square with a grill.
Ceiling Fans – as their name suggests, suspend from a ceiling and have the ability to cool whole rooms, making them great alternatives to air conditioning systems.
Tower Fans vs Pedestal FansIn general, tower fans have more and better features such as night lights and purifiers compared to pedestal fans. They also come in a variety of styles, sizes and are normally much quieter. However, tower fans are generally less powerful than pedestal fans and have a smaller output are size.
Pedestal fans are more powerful than tower fans as they have much bigger blades giving them more airflow output. This makes them an ideal choice for larger rooms. The direction of the airflow can also be easily controlled without the need to physically move the unit. However, pedestal fans tend to be much louder than tower fans. They also have limited features and variations in terms of style and size.
Key ConsiderationsFan Power - A combination of two key factors determines how powerful a fan is: the size of the fan and its speed settings
Fan Size - A small fan suits a small space, while a bigger fan is suits a larger space.
Fan Speed - A fan with higher speed settings and a higher wattage provides more power and airflow.
Fans by Room SizeYou a fast, portable cooling solution is needed in a bedroom, pedestal fans work well because the height can be adjusted and angled so the unit is facing the bed (with the fan facing one direction or oscillating around), whereas tower fans tend to suit living room areas because they’re more compact and can be positioned out of the way.
If something more permanent is required for the home, a ceiling fan is a cost-effective way to cool bedrooms and living rooms. Ceiling fans require a ceiling height of at least 2.1-2.4m to perform best, and the fan may be need to be lowered if the ceiling is higher.
Ceiling fans also consume less electricity than air conditioners, and most pedestal fans and tower fans (depending on which fan speed they are using)
Fans with a DC motor are the most efficient to run.
Fan Noise LevelsIt is important to take consideration of the noise level a fan will produce when operating.
A loud desk fan can break concentration while working and the fans close proximity can make the noise more noticeable, so it is important to look at a desk fan with a quiet noise level.
For a bedroom fan, a unit that won’t disrupt sleep will needed. Tower fans are generally quieter than pedestal fans, and many come with night modes.
*It is always important to check the rooms requirements against the fans specifications before purchasing.
