An auxiliary method and apparatus therefor for cooling refrigerated enclosures equipped with a primary refrigerating system, includes an intake opening mounted in fluid communication with a source of cold air and a blower having its inlet connected in fluid communication with the intake opening to draw cold air from the source of cold air, such as cold outside ambient air. The blower is mounted within a heated enclosure to prevent the blower housing from collecting moisture therewithin. A discharge opening is provided in the walls surrounding the refrigerated enclosure and a conduit connects in fluid communication the outlet of the blower and the discharge opening for supplying the cold air to the interior of the refrigerated enclosure when the blower is activated. Thermostats are provided for controlling the turning on and off of the blower, and, in this regard, the auxiliary unit is activated when the temperature of the cold air falls below a predetermined value and when the temperature in the refrigerated enclosure falls below another predetermined temperature below the setting of the thermostat for the primary refrigeration unit. A diverting device is mounted at the discharge opening to direct the cold air away from objects, such as comestibles, within the refrigerated enclosure to prevent them from being damaged by the cold air.
