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.

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.
