Abstract
Frost in a freezer and/or traffic between the freezer and an anteroom is controlled. The frost is controlled by estimating a condition of the anteroom that promotes the frost in the freezer and by opening a door in the doorway in response to the estimated condition in order to supply cold air from the freezer to the anteroom. The traffic between the freezer and the anteroom is controlled by detecting the traffic approaching the doorway and by opening the door in the doorway in response to the detected traffic.
