1. Optimizing Electricity Usage with Fans During Hot Seasons
Discover some common mistakes and hacks when using fans in hot seasons to reduce electricity costs for your family while still effectively cooling your home.
Apart from various solutions like air conditioning and misting fans, electric fans are still considered the most basic cooling device that every Vietnamese household equips for the upcoming hot season. However, using electric fans effectively, minimizing electricity costs, and avoiding regrettable mistakes are things that not everyone grasps.
Here are some common misconceptions about electric fans that readers can refer to for optimizing and effectively using this cooling device.
Turn on the fan at a high setting to save electricity
Some people believe that turning the fan to a high setting means less electrical wire winding (lower resistance), hence less electricity consumption. Conversely, when the setting is low, the fan speed is slower because the current runs through more winding (higher resistance), resulting in higher electricity consumption.
Therefore, even if it's not very hot, some people still turn the fan to the highest setting with the reason of 'saving electricity'. However, applying physics knowledge, a high setting fan means higher power consumption, equivalent to higher electricity consumption.
Using measuring devices in real conditions, it can be seen that for a standard desk fan in Vietnam with 3 cooling levels, setting 1 (lowest) consumes about 30W, setting 2 consumes 36W, and setting 3 consumes 43W.
However, if we consider the criteria of airflow / consumption ratio, a higher setting is actually more advantageous because it cools more effectively. Therefore, choose the fan speed that feels appropriate for the weather conditions where you live.
The hotter it gets, the higher the fan setting should be
Choosing the Right Fan Speed for Hot Weather
Turning off the fan when not in use not only saves electricity but also ensures safety from fire hazards and fan damage.
