A Quick History of the type of
Refrigeration used in your
Wine Cooler...
In 1834, the French physicist Peltier discovered a very
intriguing phenomenon. When direct current goes through
different metals that are connected, one joint will produce
heat while the other will become cold at the same time.
Peltier’s discovery meant that he had found the
semiconductor (endothermic joint and exothermal joint
system). Whether the conductor joint is endothermic or
exothermal depends on the direction in which current flows
through the conductor.
This has become known as the ‘Peltier Effect’.
Semiconductor refrigeration is based on a
thermoelectric device that includes the different ‘P’ shape
and ‘N’ shape semiconductor materials placed in a certain
way. When direct current goes through, one end releases
heat while the other absorbs heat. Once the heat produced
at the exothermal joint is released, the temperature of the
endothermic joint decreases radically, resulting in cryogenic
refrigeration.
As the development and application of semiconductor
refrigeration technology develop further, it’s inevitable that
it will cause a revolution in the refrigeration industry,
radically changing the traditional monopoly of compression
refrigeration …
… This is especially important in protecting the
environment.
