Abstract

PURPOSE: To achieve a decrease in cooling load and equalization of temperature distribution in the storage by setting the ratio to be 2 or more between the diameter of a blowoff opening and that of a suction opening to improve an outside air shutoff capacity. CONSTITUTION: A cooler 14 is installed on a rear in a duct 12 for an cool air curtain to form a cool air curtain circuit 13 of an open showcase 10. The flow of cooled air cooled by the cooler 14 is blown in circulation by a blower 15 provided on a bottom part in the duct 12. The diameter of the opening of a diffuser part 16 of the duct 12 for the cool air curtain is made more than twice as large as that of the opening of a suction part 17 thereof. This enables better prevention of the entrainment of outside air at the suction part to improve the outside air cutting capacity thereby achieving a decrease in cooling load and an equalization of the temperature distribution in the storage.
