Technical Terminology
•
Refrigerant
Liquids that can be used to a generate a cooling
effect are known as refrigerants. They have a rela-
tively low boiling-point, indeed so low, that the
warmth from the food stored in the fridge or
freezer can cause the refrigerant to boil and
vaporise.
•
Refrigerant Circuit
Closed circulation system that contains the refrig-
erant. The refrigerant circuit comprises primarily
of an evaporator, a compressor, a condenser and
pipe work.
•
Evaporator
The refrigerant is evaporated in the evaporator.
Similar to all other liquids, refrigerant requires
heat to evaporate. This heat is removed from the
interior of the appliance, as a result the interior is
cooled. The evaporator is therefore located inside
the appliance or placed in foam immediately
behind the inner wall and thus not visible.
•
Compressor
The compressor looks like a small drum. It is
driven by a built-in electric motor and is mounted
on the base of the appliance at the rear. The task
of the compressor is to draw in vaporised refriger-
ant from the evaporator, to compress it, and to
pass it on to the condenser.
•
Condenser
The condenser normally has the form of a grid.
The refrigerant compressed in the compressor is
liquefied in the condenser. During this process,
heat is released to the surrounding air at the sur-
face of the condenser. The condenser is mounted
on the base of the appliance.
