COMPRESSOR, AND CONTROL METHOD FOR SAME

A compressor includes: a compressor body that suctions and compresses a gas to be compressed; heat exchangers that circulate a cooled target inside the heat exchangers to cool the cooled target; a fan that is driven by a fan motor and that sends a cooling gas to the heat exchangers to remove heat; a...

More Information
Summary:A compressor includes: a compressor body that suctions and compresses a gas to be compressed; heat exchangers that circulate a cooled target inside the heat exchangers to cool the cooled target; a fan that is driven by a fan motor and that sends a cooling gas to the heat exchangers to remove heat; a temperature sensor that detects an initial cooling gas temperature that is a temperature of the cooling gas not having been subject to heat removing for the heat exchangers; and a control unit that is capable of setting an upper limit frequency that is an upper limit for controlling a rotational frequency of the fan motor. The control unit sets the upper limit frequency to a rotational frequency equal to or lower than a frequency at which current at an acceptable current level is supplied to the fan motor, at each of the initial cooling gas temperatures detected by the temperature sensor.
