PROBLEM TO BE SOLVED: To prevent suction/exhaust air from going in/out in refrigeration circuits adjacent to each other. SOLUTION: Two refrigeration circuits 11, 12 are juxtaposed inside a common machine room 3. In this situation, a cover 26 of an evaporator 17 in one refrigeration circuit 11 is arranged so as to be interposed between both refrigeration circuits 11, 12. A shield plate 36 is put up between the cover 26 and a rear face 3A of the machine room 3. When condenser fans 19 of both refrigeration circuits 11, 12 are driven, the outside air is sucked from intake openings 33 of the rear face 3A of the machine room 3 to cool condensers 15, and exhaust air is exhausted from exhaust openings 34 of a ceiling face to the outside of the machine after compressors 14 are cooled. At that time the cover 26 of the evaporator 17 of the refrigeration circuit 11 is arranged so as to interrupt between both refrigeration circuits 11, 12, and since the shielding plate 36 is provided between the cover 26 and the rear face 3A of the machine room 3, the situation in which suction/exhaust air by each condenser fan 19 goes in/out between both refrigeration circuits 11, 12 is avoided.
