| 摘要 |
The problem addressed by the invention is that of improving the operating reliability of a refrigerant compressor system comprising a first refrigerant line that conducts expanded refrigerant, a second refrigerant line that conducts compressed refrigerant, at least one refrigerant compressor, which is arranged between the first and the second refrigerant lines and which is driven by a motor, and a control unit for operating the refrigerant compressor system. This problem is solved in that the control unit has a first central processor unit and at least one input/output unit for control variables that communicates with the first central processor unit, and that a second central processor unit is associated with the first central processor unit, which second central processor unit takes over the control functions for controlling the refrigerant compressor system if the first central processor unit fails. |
