Subsequently, the operation will be described. When cooling the refrigerating compartments 6A to 6C, both the refrigerating circuits 11, 12 and the in-compartment fan 31 provided for each of them are driven. First refrigeration circuit 11
On the side, the cool air generated near the evaporator 17 is
The cold air blown into the duct 22 by the in-compartment fan 31 and blown down the duct 22 to the left and right refrigerating compartments 6A and 6B through the ventilation port 23 while descending in the duct 22, and the cold air blown out to the left refrigerating compartment 6A continues to the left refrigerating compartment. 6A, the cold air blown into the refrigerator compartment 6B on the right side flows into both ducts 2A.
After flowing to the left refrigerator compartment 6A through the gap between the two, it rises in the same way, and generates a circulating flow such that it is guided from the suction port 29 to the evaporator 17 side, and thus both refrigerator compartments 6A, 6B
Is cooled. On the second refrigeration circuit 12 side, cool air generated in the vicinity of the evaporator 17 is blown into the left side of the refrigerator compartment 6C by the in-compartment fan 31, and the in-compartment air flows from the right side to the suction side of the evaporator 17.

When the condenser fan 19 is driven, the outside air is sucked through the intake port 33 on the rear face 3A of the machine room 3 and passes through the condenser 15, thereby cooling the condenser 15 and further hitting the compressor 14. After the compressor 14 is cooled by the exhaust gas, the exhaust gas is exhausted outside from the exhaust port 34 on the ceiling surface. By the way, since the two refrigeration circuits 11 and 12 are arranged side by side in the common machine room 3, when both condenser fans 19 are driven, the outside air drawn by one condenser fan 19 When part of the exhaust gas goes to the condenser 15 side of the other refrigeration circuit, and part of the exhaust gas goes to the compressor 14 side of the opposite refrigeration circuit, the intake and exhaust of both refrigeration circuits 11 and 12 occur. There is a risk of getting in and out of the room.

After passing through the condenser 44 while being bent at a substantially right angle, the condenser 44 is cooled. Further, the compressor 46 is cooled by hitting the compressor 46, and then the exhaust gas is directed along the guide surface 51 of the cover 48. The air is exhausted from the ceiling through an exhaust port 54. Also in the second embodiment, the cover 48 of the evaporator 49 in the left refrigeration circuit 41 has a function of shutting off between the two refrigeration circuits 41 and 42, and the intake and exhaust of the condenser fan 45 causes the two refrigeration circuits 41 and 42 to operate. Getting in and out between 42 is avoided.
