Technical Terminology
•
Refrigerant
Liquids that can be used to a generate a
cooling effect are known as refrigerants.
They have a relatively 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
refrigerant. The refrigerant circuit compri-
ses primarily of an evaporator, a compres-
sor, a condenser and pipe work.
•
Evaporator
The refrigerant is evaporated in the evapo-
rator. 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 eva-
porator 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 refrigerant from the eva-
porator, 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 surface of the con-
denser. The condenser is mounted on the
base of the appliance.
