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 freez- er 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 lique- fied 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.
