Abstract

A refrigerator including a housing with a chassis and a door enclosing a chilled interior; and a pressure equalization valve extending through a wall of the housing thereby facilitating an inflow of air from the surroundings into the interior and thereby blocking an outflow of air from the interior into the surroundings, the refrigerator comprising, a wall having a throughbore formed therein in a parallel flow arrangement with the pressure equalization valve, through which air can pass in two directions, wherein the flow of air is less than that of the airflow through the pressure equalization valve in the throughflow direction and greater than that of the air leakage value of the pressure equalization valve in the blocked direction.
