An air circulation system for a refrigeration apparatus provides a controllable baffle for selectively opening or closing dual output ports. Particularly, the refrigeration apparatus includes an evaporator and an evaporator fan providing flow of refrigerated air. The fresh food compartment is to be cooled by the refrigerated air. First and second air inlet passages are provided in communication with the fan and upper and lower zones in the compartment for delivering refrigerated air in the compartment. First and second air outlet passages are provided in communication with the compartment and the fan for returning air from the compartment upper and lower zones to the fan. A baffle is mounted at the first and second air outlets and has independent open positions for each outlet allowing movement of air through its associated zone, and a closed position for each outlet preventing movement of air through such zone. A control is provided for selectively operating the baffle to assume any one of four positions for selectively opening or closing each port outlet according to the sensed temperature in the zone as compared to a desired temperature.

A refrigeration apparatus comprising: a compartment to be cooled by refrigerated air; refrigerated air providing means for circulating refrigerated air; air inlet means for providing an air inlet passage, through which air flows from the refrigerated air providing means to said compartment; first air outlet means for providing a first air return passage, through which air flows from said compartment to said refrigerated air providing means; second air outlet means for providing a second air return passage, through which air flows from said compartment to said refrigerated air providing means; baffle means for selectively and independently opening and closing said first and second air return passages, said baffle means comprising a unitary baffle positioned at both said first and said second air outlet means; and temperature control means operatively associated with said baffle means for controlling said baffle means to selectively open and close said first and second air return passages to control the movement of air through said compartment to maintain said compartment at a desired temperature.
