PROBLEM TO BE SOLVED: To provide a rotary compressor and a refrigerating/cooling system, which will not spoil the chemical stability of lubricating oil or difluromethane even when the difuoromethane is used as a refrigerant and which is high in performance and reliability. SOLUTION: A plurality of rotary compressing elements are received in one unit of sealed vessel and a refrigerant circuit, in which refrigerant sucked from the outside of the sealed vessel is compressed sequentially by the plurality of compressing elements and, thereafter, is discharged to the outside of the sealed vessel, is constituted while difluoromethane is employed as the refrigerant and in the refrigerant circuit, connecting the rotary compressing element, incorporates an intermediate cooler 35.
