COLD RESERVING STORAGE

PROBLEM TO BE SOLVED: To equalize distribution of inside temperature of a cold reserving storage loaded on means of transport such as refrigerator trucks, trucks, trains, ships and aircraft. SOLUTION: In this cold reserving storage 12 loaded on the means of transport 10 and including an air cooler 28 having a suction opening 34 and a supply opening 36 at one end of a loading space S, a cold air duct 38 is connected to the air cooler 28, the cold air duct is extended to at least a central region of the loading space S along a ceiling surface 13, and the cold air c is supplied from the supply opening 40 of the extended end, so that an upper circulation flow c1 for returning the cold air c toward the suction opening 34 of the air cooler 28 along an uppermost face of the load from a terminal end region of the loading space S, a lower circulation flow c2 for allowing the cold air c to flow downward from the terminal end region of the loading space S and returns toward the suction opening 34 through a ventilation space s1 formed on a pallet 20 on which a load f is placed, and a return inflow channel s2 for guiding the upper circulation flow c1 and the lower circulation flow c2 to the suction opening 34.
