Abstract
The invention relates to a refrigerant for a cooling device (10) comprising a cooling circuit (11) comprising at least one heat exchanger (12), the refrigerant undergoing a phase transition in the heat exchanger, the refrigerant being a refrigerant mixture composed of a fraction of carbon dioxide (CO2), a fraction of 1,1-difluoroethene and a fraction of at least one other component, wherein the fraction of carbon dioxide in the refrigerant mixture is 45 to 90 mole percent, the fraction of 1,1-difluoroethene being 5 to 40 mole percent.
Claims11
A refrigerant for a cooling device having a cooling circuit comprising at least one heat exchanger in which the refrigerant undergoes a phase transition, the refrigerant being a refrigerant mixture composed of 70 to 74 mole percent of carbon dioxide (CO2), 14 to 18 mole percent of 1,1-difluoroethene (C2H2F2), 2 to 6 mole percent of pentafluoroethane (C2HF5), and 5 to 10 mole percent of fluoroform (CHF3).
