Abstract
Refrigerant compressor includes an electrical drive unit, a piston/cylinder unit which can be driven by the drive unit for the cyclical compression of refrigerant, and at least one sound-damping unit made of a thermoplastic, through which sound-damping unit refrigerant can flow and which sound-damping unit includes at least one damping chamber. The at least one sound-damping unit is connected to the piston/cylinder unit in order to enable an exchange of refrigerant between the sound-damping unit and piston/cylinder unit. The at least one sound-damping unit includes at least in sections a functional surface. The functional surface is embodied such that an emissivity of a section of the sound-damping unit includes the functional surface is less than 0.7. The at least one sound-damping unit or at least one of the sound-damping units is embodied as a discharge muffler arranged downstream of the piston/cylinder unit in the direction of flow.
