Electric fans, also known as electric fans or mechanical fans, are devices powered by electricity used to create air currents to reduce body heat, cool down, and provide comfort. When operating, electric fans consist of fast-rotating fan blades creating airflow from behind the fan to the front. However, under hot sunny conditions with high temperatures, things don't go smoothly as expected.
In addition, many people mistakenly believe that the stronger the electric fan, the cooler it will be. However, this is not entirely true. When we turn the fan on at high speed, the fan's airflow is stronger and faster. In hot weather, air from the fan is pushed away, creating a void in front of the fan and quickly filled back with hot air in the room. Turning the fan on stronger and continuously makes hot air blow onto the body, causing the skin to dry quickly due to water loss, increasing discomfort and stuffiness.
Furthermore, you should only turn on the fan at low speed, allowing the fan to rotate evenly to create a gentle airflow and freshen the air, instead of directing the fan directly towards people at high speed. At the same time, do not let the fan run continuously but let it 'rest' for 10 - 20 minutes to limit the decrease in air humidity in the room, reduce skin dryness, and maintain the fan's lifespan.
Moreover, choose a well-ventilated location for the fan in the room with few obstacles to the airflow. Place the fan facing open doors, ventilated doors, skylights... to ensure efficient air circulation in the room; do not place the fan at the windward position as this will cause the fan to push hot air from outside in when the weather is sweltering. Of course, no matter how much you optimize, the electric fan still plays a role as an alternative solution if you cannot or have not installed air conditioning for the room.
