Abstract: A refrigerator is divided into a freezing compartment and a cooling compartment. An intermediate partition wall separates the compartments. The partition wall is vertically adjustable for increasing a volume of one of the compartments while simultaneously reducing a volume of the other compartment. The door carries a vertically adjustable sealing member for engaging a front surface of the partition wall. The freezing compartment includes an evaporator separated from the remainder of the freezing compartment by a vertical isolating wall, a portion of which isolating wall is spring-biased toward the partition wall.
