Patent ID: 8235673

Claim:
A control method of an inverter compressor that has a motor operated by an inverter, a main body of the compressor rotationally driven by the motor, an oil separator separating a lubricant from a compressed air of the main body of the compressor and a discharge valve discharging the pressure on the discharge side of the compressor, wherein when the inverter trip occurs, the discharge valve is opened to lower the pressure on the discharge side of the compressor, and in case that an operation elapsed time tm from the time the inverter is started to the time the trip occurs is shorter than a preliminarily-set standard elapsed time t 3 , the inverter compressor waits for a retry waiting time shorter than a retry waiting time in case that the operation elapsed time tm is longer than the standard elapsed time t 3 , then, when the retry waiting time elapses, the discharge valve is closed, and the inverter is restarted.
