Abstract (en)
[origin: WO2014173641A1] The invention relates to a method and a device for cooling an engine, wherein the engine drives at least one at least two-stage compressor (2) of a refrigerant circuit (1), which compressor comprises at least a first compression stage (3) and a second compression stage (4), wherein a refrigerant is conducted through the refrigerant circuit (1), which refrigerant is raised from a low pressure level to a medium pressure level in the first compression stage (3) and from the medium pressure level to a high pressure level in the second compression stage (4) and, subsequently to the second compression stage (4), is expanded to the medium pressure level with a release of heat.
