In automatic-defrost freezers and refrigerators (and in larger-capacity units) that require a more rapid cooling of the condenser, additional air movement through the condenser is provided by a fan (called forced draft cooling). Air is drawn into the compressor compartment from one side of the front grille, circulated through the condenser, and expelled through the other side of the front grille.
In some side-by-side models, air is expelled at the rear of the compressor compartment. In addition to the rapid cooling of the condenser, the condenser fan also causes rapid evaporation of water in the condensation tray.
