Abstract
A refrigerant compressor for air-conditioning systems and to a method for operating a refrigerant compressor, is based on the object of specifying a solution with which safe functioning of a refrigerant compressor is achieved and in which the effort during production of the refrigerant compressor and the costs are reduced.
Claims9
A refrigerant compressor for an air-conditioning system, comprising:
- a filter arranged in a region in front of a spiral nozzle insert of the refrigerant compressor, as seen in a direction of a mass flow of a refrigerant of the refrigerant compressor, to prevent blockages in the refrigerant compressor, wherein an annular channel surrounding a molding is arranged on a central housing of the refrigerant compressor, that the molding has a circular ring-shaped flat face, and that a friction plate is arranged parallel to the circular ring-shaped flat face, wherein a gap acting as the filter is formed between the circular ring-shaped flat face and the friction plate.
A method for operating a refrigerant compressor, in which particles exceeding a predefined size are filtered out in a region in front of a spiral nozzle insert of the refrigerant compressor, as seen in a direction of a mass flow of a refrigerant of the refrigerant compressor, wherein an annular channel surrounding a molding is provided in a central housing of the refrigerant compressor, that the molding is provided with a circular ring-shaped flat face, and that a friction plate is provided parallel to the circular ring-shaped flat face, as a result of which a filter which retains the particles exceeding the predefined size is formed by a gap between the circular ring-shaped flat face and the friction plate.
