Peltier

What is a Peltier element?

This is an electrical component that controls heating and cooling.

When electricity is passed through the element, the phenomenon where one side is “heated” and one side is “cooled” occurs. This is a heat movement phenomenon (heat pump) caused by the temperature difference between the high-temperature side that dissipates the heat and the low-temperature side that absorbs it. The temperature can be adjusted by changing the amount of electricity flowing. Further, the cooling and heating can be reversed by changing the direction of the electricity flow. This action is called the “Peltier effect” and it can be easily used to adjust the heating and cooling temperature.

Advantages of Peltier Element

Difference between “Electronic Cooling” and “General Refrigeration Cycle Method (Compressor / Refrigerant Freon)”

• This is a green technology that does not use the ozone layer to destroy Freon or emit any greenhouse effect gases.
• It is compact and lightweight and does not produce any noise or vibration during operation.
• Heating, as well as cooling, is possible just by the electricity flow direction. Constant temperature control is possible even close to room temperature using both the cooling and heating functions that are proportional to the amount of electricity.
• The excellent temperature responsiveness provides immediate cooling and heating.
• Accurate temperature control is possible using just a simple device. Operation is possible using just electric wires, so building in and handling is easy.
