The fan: stirring air for a feeling of freshness
Unlike an air conditioner or air cooler, a fan doesn’t lower the temperature of a room, it simply stirs the air to give an instant sensation of freshness.
Its efficiency will vary according to its airflow capacity, and the possibility of adjusting the blast and rotation of the device, which can, for example, rotate on itself.
Advantages: lower cost, zero ecological impact. Limitations: the sensation of coolness is fleeting and artificial. It’s the same principle as with a fan: as soon as you turn it off, you feel even hotter than before, which is why you’re tempted to leave it running continuously… and come out with a nasty cold.
