PROBLEM TO BE SOLVED: To maintain reliable and stable operation even at a low load time. SOLUTION: The refrigeration system is provided with a refrigerating cycle comprising a compressor 7 driven with a variable capacity, a condenser 9, an expansion valve 13, and an evaporator 15, and a cooling load provided with a cooler 11 including the expansion valve 13 and the evaporator 15, and cooled by a coolant cooled by the cooler 11. The coolers 11 are plurally provided in parallel between the compressor 7 and the condenser 9, an operation capacity is controlled based on a suction pressure of the compressor 7 in the compressor 7, and the number of coolers 11 to be operated is controlled based on the operation capacity.
