  • the present invention relates to a refrigerator with backwall condenser. Via the condenser, heat extracted from the storage chamber of a refrigerator is released to the environment. For energy-efficient operation of the refrigeration device, it is therefore crucial that the heat can flow away quickly and unhindered from the back wall condenser.
  • the condenser When a refrigerator with backwall condenser is installed in a household, the condenser is generally located in a small gap between the back of the refrigerator housing and an opposite building wall.
  • Condenser heats the air in the gap, he brings a Konvezzysströmung in motion. Heated air flows upwards out of the gap and is replaced by the cooler ambient air flowing in from below. So the back wall condenser is constantly lapped by cool air.
  • the strength of the convection flow depends decisively on the width of the gap. In a gap that is too narrow, the air flow is too much damped by friction on the split walls to allow efficient convection to form. If the gap is too wide then heated upwardly flowing air at the condenser will mix on its way with cooler air located in the gap at a greater distance from the condenser. The resulting buoyancy remains low, and it takes a long time for the gap to heat up to its full depth. Since the back wall condenser usually releases heat only in phases, a heat release phase is usually already finished again before the gap is heated homogeneously and an efficient convection flow is initiated.
