  • the conduit system 84 can include the tube 110, but not the refrigeration conduit 110A fluidly coupled to the freezer conduit 128, to direct airflow from the freezer compartment 22 into the refrigeration compartment 20 as the refrigeration door 14 is moved to the open position 30 or from the refrigeration compartment 20 into the freezer compartment 22 as the freezer door or drawer 16 is moved to the open position 30.
  • the conduit system 84 can include the refrigeration conduit 110A fluidly coupled to the freezer conduit 128, but not the tube 110, to direct airflow from the freezer compartment 22 into the refrigeration compartment 20 as the refrigeration door 14 is moved to the open position 30 or from the refrigeration compartment 20 into the freezer compartment 22 as the freezer door or drawer 16 is moved to the open position 30.
  • the conduit system 84 can include both the tube 110 and the refrigeration conduit 110A fluidly coupled to the freezer conduit 128 to direct airflow from the freezer compartment 22 into the refrigeration compartment 20 as the refrigeration door 14 is moved to the open position 30 or from the refrigeration compartment 20 into the freezer compartment 22 as the freezer door or drawer 16 is moved to the open position 30.
  • the drawings include both embodiments simultaneously for ease of description, but the refrigeration appliance 10 could include just one of the embodiments to the exclusion of the other. Note that in the instances where the refrigeration appliance 10 includes the tube 110 but not the refrigeration conduit 110A fluidly coupled to the freezer conduit 128, the refrigeration appliance 10 can additionally include the refrigeration conduit 110A and the freezer conduit 128 in separate fluid communication with the drain pan 144.
  • Incorporating the conduit system 84 with the refrigeration conduit 110A fluidly coupled to the freezer conduit 128 but not the tube 110 may be advantageous to decrease the number of apertures (such as eliminating apertures 102, 108) through the refrigeration passthrough 98 and the freezer passthrough 104, because the apertures 136, 120 for the freezer conduit 128 and the refrigeration conduit 110A, respectively, may need to be included anyway to drain condensate from freezer evaporator 124 and the refrigeration evaporator 106.
  • the embodiments of the conduit system 84 of the present disclosure address the problem described in the Background, because, as the user pulls the refrigeration door 14 toward the open position 30, the conduit system 84 allows airflow from the freezer compartment 22 to the refrigeration compartment 20. The additional airflow into the refrigeration compartment 20 lessens the air pressure differential between the air within the refrigeration compartment 20 and atmospheric air pressure. The user thus uses a lesser pulling force to move the refrigeration door 14 to the open position 30 compared to if the refrigeration appliance 10 did not include such a conduit system 84.
  • the conduit system 84 may reduce moisture imbalance between the refrigeration compartment 20 and the freezer compartment 22 compared to if no conduit system 84 was included to allow air to flow between the refrigeration compartment 20 and the freezer compartment 22.
  • the reduction in the moisture imbalance could mean a reduced relative humidity within the refrigeration compartment 20.
  • the reduced relative humidity reduces the volume of insulation needed to cover refrigeration cycle lines within the refrigeration compartment 20, which leads to increased capacity for the refrigeration compartment 20 to hold food items 24.
