The invention provides a starting control method and system of a direct current frequency conversion air conditioning compressor. The starting control method and system is applicable to the field of refrigeration equipment control. According to the starting control method and system of the direct current frequency conversion air conditioning compressor, the corresponding working current is output to a motor of the air conditioning compressor within a preset starting time after a direct current frequency conversion air conditioning powers on so as to enable the motor of the air conditioning compressor to be rapidly started to work, the working current is adjusted according to a preset current frequency increment value if the motor speed of the air conditioning compressor is smaller than the target balance speed when the preset starting time arrives so as to enable the motor speed of the air conditioning compressor to reach the target balance speed, and accordingly the motor speed of the air conditioning compressor can be increased to the target balance speed within a short time so as to achieve the rapid starting of the air conditioning compressor and the booting refrigeration or heating speed can be increased.
