  • Patent number: 5816060
    Abstract: An air flow control arrangement for a side-by-side refrigerator which results in temperature variations, both spatial and temporal, of approximately about .+-.1.degree. F. in the fresh food compartment, is described. Such air flow control also is believed to even further reduce the internal "sweat" in the fresh food compartment. In one embodiment, and with respect to a side-by-side refrigerator, the middle duct in the center mullion wall is closed off, and a duct is added in the center mullion wall, or could be installed as a separate duct outside the mullion, connecting a supply port in the top, back, left hand corner in fresh food compartment to a position in the evaporator chamber. The added duct also seals off direct airflow between the evaporator chamber and the fresh food compartment.
