The disclosure relates to a method and a device for providing zeotropic refrigerants in which the refrigerant is formed from a refrigerant blend of at least two components, the components being added to a container in the ratio of their respective mass fractions to the refrigerant, and the refrigerant blend being formed in the container, wherein the temperature and/or the pressure in the container is set by means of a control device such that the refrigerant is present exclusively in the gas phase or exclusively in the liquid phase.

Method and device for providing zeotropic refrigerants

A test chamber () for conditioning air has a test space (), and a temperature control device () for controlling the temperature of the test space and allowing a temperature in a range of &#x2212;80&#xb0; C. to +180&#xb0; C., preferably &#x2212;100&#xb0; C. to +200&#xb0; C., to be established within the test space, the temperature control device having a cooling device () with a cooling circuit (), a heat exchanger (), a compressor (), a condenser (), and an expansion element (), wherein the refrigerant is a nearly azeotropic and/or zeotropic refrigerant mixture of a mass percentage of carbon dioxide and a mass percentage of at least one of the components ethane, ethene, hexafluoroethane, pentafluoroethane, monofluoro-ethane, 1,1-difluoroethene, fluoromethane and/or propane and/or xenon, the refrigerant having a relative CO2 equivalent of &#x3c;3000, preferably &#x3c;500, in particular preferably &#x3c;10, with respect to 20 years.
