ABSTRACT:
If the ambient temperature of a pressure volute measured by a temperature sensor exceeds 0° C., a compressor is instantly started at normal operation. If the temperature of the pressure volute measured by the temperature sensor is 0° C. or lower, vibration along the axial direction is given to the rotary shaft by way of an axial magnetic bearing. If the vibration amplitude of the thus given vibration exceeds a predetermined value, the compressor is started at normal operation after idle operation. On the other hand, if the vibration amplitude is lower than a predetermined value, the heater is actuated to heat the pressure volute only for a predetermined time. Thereafter, the ambient temperature is detected again, and if the ambient temperature exceeds 0° C., the compressor is started.
