PURPOSE: To display commodities different in temperatures by providing a second inlet port between an outlet port and a first inlet port and providing, a second cold air passage which is formed between a shelf extending rearward from the second inlet port and a first cold air passage and which leads from the second inlet port to a blowing fan.
CONSTITUTION: Cold air blown from an outlet port 13 is mostly sucked in a second inlet port 14 to pass through a second cold air passage 7 and is led to a blowing fan 17, while the remaining port of cold air is sucked in a suction port 15 to be led to the blowing fan 17, where both the cold air streams are joined together and accelerated by the fan 17. With this arrangement, an infiltration quantity of the external air at an opening 10 of a first storage chamber 8 is small, and a cold air curtain is formed. On the other hand, an infiltration quantity of the external air at an opening 11 provided below the second inlet port 14 is large, and an incomplete cold air curtain is formed. These cold air curtains are circulated in the first and a second storage chambers 8, 9, and the second storage chamber 9 is cooled at a temperature higher than that in the first storage chamber 8.
