PROBLEM TO BE SOLVED: To provide a refrigerating unit capable of efficiently controlling a capacity within a wide range. SOLUTION: The refrigerating unit is provided with a compressor 21, a condenser 22, a first electronic expansion valve 23A, a second electronic expansion valve 23B, a first evaporator 24A and a second evaporator 24B, and is constituted so as to repeat the change of state by circulating a refrigerant through a refrigerating cycle consisting of refrigerant pipelines 25 sequentially connecting the instruments. The first evaporator 24A and the second evaporator 24B are divided into two systems having different capacities. Further, the first evaporator 24A and the second evaporator 24B are equipped with the first electronic expansion valve 23A and the second electronic expansion valve 23B in the respective systems.
