01.01.2021The fundamental principle of the thermoelectric generator is the thermoelectric effect. In the thermoelectric effect, based on a temperature gradient, the electrons are moved from one place to another place. The temperature gradient is obtained, when there is a difference in temperature levels between two points. Thermoelectric Generator

First, it removes refrigerant from the evaporator and ensures that the pressure in the evaporator remains low enough to absorb heat at the correct rate. Second, it raises the pressure in outgoing refrigerant vapor to ensure that its temperature remains high enough to release heat when it reaches the condenser.
