PROBLEM TO BE SOLVED: To stabilize the preserving quality of foods by averaging indoor temperatures, in a forced ventilation cooling system refrigerating chamber. SOLUTION: An air circulation duct 26 is provided at the central rear part in a refrigerating chamber 17 in a vertical direction and an air circulating fan 27 is provided at the lower part of the duct 26 to such air in the lower part of the chamber and discharge the same into the upper part of the chamber. Cold air discharging ducts 23 are arranged in a vertical direction at both sides of the rear part in the refrigerating chamber 26 with a predetermined space between the air circulating duct 26 whereby the cooling temperature distributions in the vertical and transverse directions in the chamber are averaged. |
