Peltier Effect (Thermoelectric Phenomenon)
The Peltier effect is a thermoelectric phenomenon discovered in 1834 by physicist Jean-Charles Peltier. It involves the movement of heat induced by an electric current when two conductive materials are connected at points of contact.
When a direct current is applied to two metal plates, the plate carrying positive electrons becomes hot, while the plate carrying negative electrons becomes cold.
This phenomenon is widely used for air dehumidification:
- Humid air moves between two electrically charged metal plates,
- The temperature difference between the plates allows water molecules to be extracted from the air,
- These water molecules form condensation,
- The liquid water is then collected in the dehumidifier's reservoir.
