PROBLEM TO BE SOLVED: To provide a refrigeration unit comprising a mixed refrigerant adjusting means for adjusting a mixture ratio to enlarge fields utilizing the mixed refrigerant adjusting means for adjusting ratio, with respect to the refrigeration unit wherein the mixture ratio is adjusted and controlled. SOLUTION: In this refrigeration unit wherein a condenser 2 for condensing and liquefying the mixed refrigerant, an evaporator 15 for evaporating the mixed refrigerant, a compressor 1 for compressing the evaporated and vaporized mixed refrigerant, and discharging the same to the condenser 2, and mixing refrigerant adjusting means (4, 6, 8), (16, 18, 19), (24, 25) for adjusting the mixture ratio of each refrigerant of the mixed refrigerant, are connected by predetermined ducts, the mixed refrigerant adjusting means adjusts the mixture ratio to lower a ratio of the refrigerant of low boiling point in the evaporator 15 to reduce the operation noise of the compressor 1.
