A heat pump is a device which uses mechanical or electric energy
to pump thermal energy from a medium A into a medium B. The heat Q
conducted to the medium B is greater than the used mechanical or
electric energy E0. The Q factor (performance) of a heat
pump is described by the so-called "coefficient of performance"
ε = Q / E0. It is always necessary to
apply ε > 1.
The heat pump is known by the students as an important element for
alternative heat-engineering. In this industry, compression heat
pumps are primarily used.
In this experiment a Peltier-heat pump is used. The most important
quality of a heat pump, that the coefficient of performance is
bigger than 1, is also valid here:
The heat pump delivers more thermal energy than utilized electric
energy, since it extracts heat from another medium (from the
surroundings). For this purpose, solar collectors or geothermal
energy, among other things are used.
