Thermoelectric (Peltier) coolers are semiconductor devices that function like small heat pumps. They consist of plates that heat up on one side and cool down on the other, operating on direct current and produced in various power levels depending on the direction of the current.
Metal-coated ceramic is used as the lateral plate to provide thermal conductivity, electrical insulation, and mechanical strength.
In Peltier technology, the absence of moving parts eliminates unwanted elements such as noisy vibrations, wear and tear, and oil leakage, making it easy to control capacity and temperature by simply reducing or increasing the current intensity, which is a significant advantage.
Peltier system minibars are environmentally friendly as they do not contain any refrigerants.
The most significant feature of Peltier cooling technology is its 35% lower electricity consumption compared to absorption system coolers.
In Turkey, minibar production using Peltier technology was first realized with the ISM brand.
