The thermoelectric principle was first discovered in 1834
by J.C.A. Peltier – that’s why the temperature producing
parts of thermoelectric systems are described as Peltier
elements. It is based on the fact that – depending from
the polarity – cold or heat is generated when a direct
current (DC) flows through a junction of two dissimilar
metals. This cooling or heating power is still increased
by heat exchangers and fans. It is sufficient for small
and medium-sized coolers.
Compressor devices are running with the help of a
refrigerant. This cooling agent changes from the liquid
to the gaseous state inside the evaporator.
At the same time the evaporator binds the warmth
from the interior of the cooling device – it’s getting
cold. The compressor draws in the gaseous refrigerant,
compresses it and passes it on to the condenser, where
the binded heat is released again. The refrigerant
changes to the original liquid state once more and flows
back to the evaporator, where the cycle starts again.
Concentrated solution of ammonia is heated up to a
vaporous state in a tank. Under high pressure, this gas
enters a condenser where it is liquefied. There it is
supplied with hydrogen, which causes the liquid
ammonia to evaporate. At the same time heat is
extracted from the cooler’s interior. The ammonia gas
then enters the absorber, where it is taken up by a weak
ammonia solution. The saturated ammonia solution
flows back to the tank, and the cycle starts again.
