Abstract (en)
[origin: EP0926343A2] The coolant compressor takes the compressed coolant flow through an evaporation channel (50) from the pressure zone (30) in the outlet channel (42). An inlet opening (60) of the evaporation channel opens into the pressure zone with an abrupt cross section change. An outlet opening (54) of the evaporation channel opens into the outlet channel with an abrupt cross-section change. The cross section changes between the evaporation channel and the outlet channel and the pressure zone are at least by a factor of 5 or at least a factor of 10.
