PROBLEM TO BE SOLVED: To prevent the deterioration of the condensing capacity of a condenser when an outdoor temperature is high by a method wherein a duct, guiding air in a chamber, which is discharged out of a ventilating device, into the suction side of outdoor air of the condenser, is formed. SOLUTION: Air guiding passages 51, 52, guiding cooled air in a container from cooling air passages 48, 49 into the outdoor air suction side of a condenser 4, are bored while opening and closing lids 53, 54 are provided at the outlet ports of the air guiding passages 51, 52. When an outdoor air temperature is high and, accordingly, the condensing capacity of the condenser 4 is deteriorated, the air suction hole 32 of rotary disc 31 of a ventilating device is aligned with an outdoor air introducing port 32 and, at the same time, the opening and closing lids 53, 54 are opened. Then, a part of air in the container is introduced into the outdoor air suction side of the condenser through the air guiding passages 51, 52 and is passed through the condenser 4 while being accompanied by outdoor air, sucked into an outdoor air flow passage 36. The temperature of air, passing through the condenser 4, is lowered in such a manner and the condensing capacity of the condenser 4 is improved. |
