PROBLEM TO BE SOLVED: To appropriately adjust a condensation pressure. SOLUTION: This refrigeration device is provided with a circulation channel I of a closed refrigerant including first and second compressors 1 and 2 being arranged in parallel, an oil separation collector 5, air-cooling type first and second condensers 3 and 4 being arranged in parallel, and liquid reception equipment 6, an expansion valve 7, and an evaporator 8. In the refrigeration device, a condensation pressure is adjusted by parallelly operating and stopping fans 9a, 9b, 10a, and 10b for both condensers instead of each condenser and simultaneously increasing or decreasing the amount of wind for air-cooling the first and second condensers 3 and 4 for both condensers.
