Peltier effect: Heat pump

Principle

When direct current flows through a Peltier element, one side heats up and the other side cools down. Based on this characteristic, the mode of operation of a heat pump can be explained. The hot side is not only heated by the electric current, but also by the fact that the other side cools down. Energy is "pumped" from the cold side to the hot side. In this experiment, the temperatures and electric work are measured as a function of time. Based on these values, the electrical energy and thermal energy on both sides can be determined and the coefficient of performance as well as the efficiency can be calculated.

Benefits

• Part of a system solution - Easily expandable for further experiments
• easy teaching by using the demo board for demonstration
• Simplified implementation: all pre-settings already prepared
