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. An auxiliary air flow control fan located in a port in the center mullion wall controls air flow through the fresh food compartment, and ducts located in a middle portion of the center mullion wall are provided to allow cool air in freezer compartment to flow into fresh food compartment. Manually set dampers may be located in these ducts to control the amount of air flow from the freezer compart…
