Principle

If an electric current flows through the Peltier element, then
one side will heat up, the other will cool down. In the process,
the temperature of the warm side has an influence on the
temperature of the cold side.
This can be used, e.g., for cooling with ambient heat: If the warm
side is held at a constant temperature by air, water or earth
(geothermal energy), the cold side cools down stronger than without
storage. The aluminium block of the thermo generator is used as
storage in this experiment.

Benefits


Experiment is part of a complete solution set with a total of
17 experiments for Renewable Energy Basics and Heat energy

Direct protection of the thermocouple against overheating due
to fixed aluminum plates

Additional aluminum block for storage of heat energy


Tasks
