Compressor control method, compressor, heating and ventilation equipment and computer storage medium

The invention discloses a control method of a compressor, the compressor, heating and ventilation equipment and a computer storage medium, the compressor comprises a screw rod, a slide valve, a frequency converter and a motor, the frequency converter is used for controlling the motor to drive the screw rod, and the slide valve is used for adjusting the effective working length of the screw rod; the control method of the compressor comprises the steps of obtaining exhaust pressure of the compressor; and reducing the frequency of the motor and/or unloading the slide valve according to the condition that the exhaust pressure is greater than the preset pressure value to reduce the load of the compressor. According to the control method of the compressor, on one hand, the compressor can be prevented from being overheated, and on the other hand, the current of the motor is reduced by reducing the load of the compressor, so that the heating value of the motor is reduced, and the motor overheating fault is prevented.
