    Peltier Heat Pump
    Working model with aluminium water tanks which are thermally coupled to the surfaces of a Peltier element. When an electric current flows through the Peltier element, heat is transferred between the tanks, causing one of them to cool and the other to heat up. Each of the reservoirs has an electric stirrer to ensure even distribution of the heat. Two digital thermometers indicate the respective water temperatures. Since the specific heat capacity of the system is known, it is possible to determine the power involved in heating and cooling and for a comparison to be made with the electrical power supplied. The system is supplied in a handy transport case which also ensures sufficient thermal insulation from the surroundings.

    Peltier element:
    Supply voltage: 5 – 8 V
    Current consumption at 8 V: 2.5 – 3.5 A
    Surface area: 40x40 mm²
    Thickness: 3.7 mm
    Water tanks:
    Volume: 200 ml
    Weight: 105 g
    Stirrer:
    Current consumption: 100 mA approx.
    Carrying case:
    Dimensions: approx. 244x160x70 mm³
    Weight: approx. 920 g
