More Information
Summary: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). Cette composition de réfrigérant n'est pas susceptible de provoquer l'appauvrissement de l'ozonosphère, peut être utilisée en tant que produit de substitution dans un circuit de réfrigération classique, et permet de conserver les performances de ce circuit sans qu'il soit nécessaire de modifier celui-ci. L'invention concerne également un circuit de réfrigération dans lequel on utilise cette composition, laquelle est caractérisée en ce qu'elle comprend du R600 (n-butane; CH3CH2CH2CH3), du R125 (CHF2CF3), du R508A (R23/R116=39/61) et du R14 (tétrafluorométhane; CF4).
