Technical terminology

• Refrigerant

Circuit

• Evaporator

• Compressor

• Condenser

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.

Closed circulation system that contains the refriger-

ant. The refrigerant circuit comprises primarily of an

evaporator, a compressor, a condenser and pipe

work.

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 appli-

ance or placed in foam immediately behind the

inner wall and thus not visible.

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 evaporator, to compress it, and to pass it on to

the 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

condenser. The condenser is mounted on the base of

the appliance.
