FLUIDS FOR REFRIGERANT CIRCUITS

摘要

New refrigerant media for use in refrigeration circuits as a replacement for chlorofluorocarbons (CFCs) in view of reducing risks in connection with environmental pollution and ozone depletion in the stratosphere. Said new refrigerant media are azeotropic mixtures of isobutane (R600a) and a fluorinated hydrocarbon in a percentage ranging from 5 to 50 percent and 50 to 95 percent, respectively.
