PROBLEM TO BE SOLVED: To facilitate installation, and to improve energy-saving effect, in a rack for a freezing-refrigerating warehouse having an air curtain device. SOLUTION: This invention is characterized by installing the air curtain device 38 for shielding space between a low temperature area 16 of a freezing temperature zone, and a high temperature area 18 of a refrigerating temperature zone by an air flow of two layers, in the rack 10 arranged in the low temperature area 16, in the freezing-refrigerating warehouse 12 divided into the area 16 and the area 18. This air curtain device is composed of an upper unit 40 composed of a first air blower 42 taking in and delivering air in the low temperature area and a second air blower 44 taking in and delivering air in the high temperature area, and a lower unit 60 for sucking and returning the air flow from the first air blower 42 to the low temperature area.
