A method for operating an electromotive refrigerant compressor having an electric motor, includes operating the electric motor using a supply voltage from a second on-board electrical system. The electric motor is operated in an emergency mode if a fault in a low-voltage supply from a first on-board electrical system and/or a fault in a bus for transmitting a control signal, in particular for a desired rotation speed of the electric motor, to the electromotive refrigerant compressor, are/is detected. An electromotive refrigerant compressor, an air-conditioning installation including such an electromotive refrigerant compressor, a computer program product and a computer-readable medium, are also provided.
