PROBLEM TO BE SOLVED: To improve cooling efficiency and to drop noise. SOLUTION: In the heat radiator of an outdoor apparatus, heat caused inside a hermetic sealed outdoor casing 1 is discharged to an outer part by a heat exchanger 7. A control means measuring the air volumes of an inner air circulation fan 16 and an outer air circulation fan 17 in the exchanger 7 and controlling them so that outer air circulation air volume ≤ inner air circulation air volume is arranged. The first air volume that the inner air circulation fan 16 generates is set to be a master and the second air volume that the outer air circulation fan 17 generates based on the first air volume is set to be a slave.
