Principle
When direct
current flows through a Peltier element, a temperature difference
results: one side heats up and the other side cools down. The
temperature on the hot side influences the temperature on the cold
side and vice versa. If the hot side is held at a constant
temperature by way of a reservoir, e.g. a water reservoir, the cold
side cools more strongly than would be the case without the
reservoir. In this experiment, the temperatures are measured over
time when the thermogenerator is used without and with a "water
reservoir" on the hot side.
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
