| 摘要 |
The development of a substitutable refrigerant composition that enables a conventional refrigerating circuit to maintain its performance without changing the circuit configuration has been demanded. An object of the present invention is to provide such a refrigerant composition and a refrigerating circuit using it. A refrigerant composition of the present invention is characterized by comprising R600 (n-butane: CH3CH2CH2CH3), R125 (CHF2CF3), R508A (R23/R116: 39/61), and R14 (tetrafluoromethane: CF4).
