PROBLEM TO BE SOLVED: To contrive the stabilization of preserving quality of foods due to the averaging of indoor temperatures as well as the averaging of indoor illumination, in a forced ventilation cooling system refrigerating chamber. SOLUTION: Cold air discharging ducts 23 are arranged at both sides of rear surface in a refrigerating chamber 17 while an air circulation duct 26 for discharging air, sucked by an air circulating fan 27, into the refrigerating chamber, and an illumination cover 32, provided at the indoor side fore part of an indoor illuminating lamp 31, are arranged between the cold air discharging ducts 23. In this case, the cold air discharging ducts 23 are arranged in the same plane across a plurality of stages of racks 25. According to this method, the cooling temperature distribution in the vertical as well as the transverse directions are averaged while the distribution of illuminating degrees in the vertical direction is also averaged. |
