Abstract
The invention relates to a compression apparatus (10) comprising a turbocompressor (1) with a plurality of compression stages (1a, 1b, 1c, 1d) as well as infeed flows (5b, 5c, 5d), where the compression apparatus (10) serves for operating a refrigerant circuit, especially with a hydrocarbon gas such as propane, ethylene, methane, or a mixture thereof, wherein a mixer device (8a, 8b, 8c) is arranged outside the turbocompressor (1) and wherein a preceding and a succeeding compression stage (1a, 1b, 1c, 1d) are connected to one another via the mixer device (8a, 8b, 8c) in such a manner that the infeed flow (5b, 5c, 5d) provided for the succeeding compression stage (1b, 1c, 1d) opens into the mixer device (8a, 8b, 8c) in order to mix the infeed flow (5b, 5c, 5d) with a main flow (6a, 6b, 6c) of the preceding compression stage (1a, 1b, 1c).
