REFRIGERANT COMPOSITION AND REFRIGERATING CIRCUIT EMPLOYING THE SAME

摘要

A refrigerant composition which has no fear of causing ozonosphere depletion and which can be used as a substitute in a conventional refrigerating circuit and enable the performance thereof to be maintained without the need of modifying the circuit; and a refrigerating circuit employing the composition. The refrigerant composition is characterized by comprising R600 (n-butane; CH3CH2CH2CH3), R125 (CHF2CF3), R508A (R23/R116=39/61), and R14 (tetrafluoromethane; CF4).
