The invention relates to a method for operating an electric refrigerant compressor (12) having an electric motor (14), the electric motor (14) being operable by means of a supply voltage of a second on-board electrical system, and the electric refrigerant compressor (12) being operable by means of a supply voltage of a second on-board electrical system. The electric motor (14) is operated (continued) in an emergency mode when a malfunction of a low voltage from the first on-board electrical system and/or a malfunction of a bus (18) for transmitting a control signal to the electric refrigerant compressor (12), in particular a control signal for a target rotational speed of the electric motor (14), is detected. The invention further relates to such an electric refrigerant compressor (12) and to an air-conditioning system (8) having such an electric refrigerant compressor.

    本发明涉及用于运行电动制冷剂压缩机(12)的方法,电动制冷剂压缩机具有电动马达(14),其中,电动马达(14)能借助第二车载电网的供电电压来运行,并且其中,当检测到来自第一车载电网的低压电压发生故障和/或用于向电动制冷剂压缩机(12)传输控制信号、尤其是用于电动马达(14)的目标转速的控制信号的总线(18)发生故障时,让电动马达(14)在紧急状况模式下(继续)运行。此外,本发明还涉及这种电动制冷剂压缩机(12)和具有这种电动制冷剂压缩机的空调设施(8)。
