The development of an alternate refrigerant composition which is free from a possibility of causing depletion of the ozone layer and capable of maintaining the performance of a conventional refrigerating circuit without modifying the circuit is desired. An object of the present invention is to provide such a refrigerant composition and a refrigerating circuit using the refrigerant composition. A refrigerant composition of the present invention comprises R245fa (CF<SUB>3</SUB>CH<SUB>2</SUB>CHF<SUB>2</SUB>), R125 (CHF<SUB>2</SUB>CF<SUB>3</SUB>), R508A (R23/R116:39/61) and R14 (tetrafluoromethane: CF<SUB>4</SUB>). Thus, the refrigerant composition has no possibility of causing depletion of the ozone layer. Further, since the composition is noncombustible, possible combustion can be prevented even if it leaks.
