During the cooling process heat will be generated at the condenser fins on the backside of the refrigerator, which must be transferred with sufficient airflow to the ambient.
If there is not enough space for the air to leave, the cooling performance will drop down and the energy consumption will rise.
Incorrect ventilation could cause decline of refrigerator’s longevity.
To get the best performance the refrigerator needs at least 200 cm2 free air inlet and this space should be kept until the air outlet. Behind the rear border part please leave minimum 20 mm distance to the furniture wall.
