ABSTRACT:
An air circulation system for a refrigeration apparatus provides a controllable baffle to selectively open or close an air outlet port. Particularly, the refrigeration apparatus includes an evaporator and an evaporator fan for providing flow of refrigerated air. A fresh food compartment is to be cooled by the refrigerated air. An air inlet passage is provided in communication with the fan and compartment for delivering refrigerated air to the compartment. An air outlet passage is provided in communication with the compartment and the fan for returning air from the compartment to the fan. A baffle is mounted at the compartment air outlet and has an open position allowing movement of air through the compartment, and a closed position preventing movement of air through the compartment. A control is provided for selectively opening the baffle in response to the compartment temperature being above a desired temperature, and to close the baffle when the compartment temperature is below the desired temperature.
