The invention provides a compressor state control method and device and relates to the technical field of air conditioners. The method comprises the steps of acquiring relevant data of each compressor; computing the oil temperature superheat degree of each compressor through the data during operating; raising the frequency of each compressor with the oil temperature superheat degree less than or equal to the preset oil temperature superheat degree, and lowering the frequency of the at least one compressor with the oil temperature superheat degree greater than the preset oil temperature superheat degree. Through the compressor state control method and device provided by the invention, the oil temperature superheat degree of the compressor with too low oil temperature superheat degree is controlled to be raised to the preset oil temperature superheat degree or above on the basis of guaranteeing that the total working frequency of an air conditioner is constant; accordingly, the air conditioner can operate normally, and the service life of the compressor is prolonged.
