A control method for an air conditioning compressor, comprising: obtaining a first correction temperature according to a first actual temperature reduction correction of an inner coil; when the first correction temperature is less than a first preset temperature, controlling a compressor to perform an up-frequency operation at a first up-frequency rate; and when a first correction temperature' is greater than or equal to the first preset temperature, and when a first temperature difference is greater than or equal to a first set temperature difference, controlling the compressor to perform an up-frequency operation at a second up-frequency rate. Further provided are a control apparatus for an air conditioning compressor, and an air conditioner. At up-frequency operation stages of a compressor, the temperature rise within a set detection interval duration is used as a switching parameter of a fast up-frequency operation and a slow up-frequency operation, the degree of lag between the inner coil temperature and
