On a hot summer day, there’s nothing like sitting below a ceiling fan and enjoying a chilled beverage. Most of us take this humble electrical gadget for granted. After all, there are only a few Australian homes where you won’t find a ceiling fan of some form or the other installed and hence, it gets barely noticed. However, have you ever noticed or wondered how the design of the fans has evolved over the years? Do you know which type of fan is the best, AC or DC? Do you realise a ceiling fan’s motion can be reversed as well? Get acquainted with these and more interesting facts about ceiling fans.
How Does a Ceiling Fan Work?
Ceiling fans do not lower the room temperature. Their function is similar to a breeze that simply moves the air around your body thus cooling you by accelerating perspiration evaporation. They make an excellent alternative to air-conditioners that are much more expensive and bulkier.
Which makes a better ceiling fan, AC or DC?
Traditionally, only fans with an alternating current motor (AC) have been used and installed in homes. They are cheap and mostly trouble-free. However, all modern ceiling fans come with direct current (DC) motor. They are more efficient and lead to savings in running costs. DC fans also offer more speed settings (up to 7) as compared to AC (up to 3) ones and hence allow more control over air movement.
Ceiling fans are not just useful in summer but in winter as well. Yes, you heard it right. You can reverse the direction of the fan to make it draw air upwards than downwards. When used in conjunction with a room heater, the fan moves the warm air around without creating a downward breeze in the room. DC fans can have up to seven speed controls including a reverse motion but even if your fan doesn’t have this control, running a normal fan at the slowest speed can achieve the same effect.
The design and the features list of ceiling fans has undergone a massive evolution since they were first introduced. You can control a fan speed using a remote or a pull-down cord, change the ambience of the room using a fan integrated light, or even have your fan start and stop automatically using a sensor app on your smartphone.
Which material makes the best blades for a ceiling fan?
While most fan blades are made of aluminium or stainless steel, it isn’t uncommon to find fans with plastic or wooden blades. All of these provide a similar throw of air and cooling. However, fans made of wood and plastic blades tend to be quieter.
Role of Ceiling Height in Cooling
This largely depends on the model of fan you’ve chosen to install. The general guideline is that the minimum height of the ceiling needs to be between 2.1 m and 2.4 m. If the ceiling is higher, then an additional rod must be installed to lower the fan.
Ceiling fans are not just cost-effective coolers but can also deliver great fashion statements for your interiors. To extract maximum benefit from a ceiling fan, make sure that your room is as heat-proof as possible.
