摘要
An anti-slugging control method and control apparatus for an air-conditioning system and an air-conditioning system. The control method comprises the following steps: obtaining a discharge superheat DSH of a compressor in real time, and monitoring the discharge superheat DSH during operation of the air-conditioning system (S10); controlling a timer to start timing if the discharge superheat DSH is less than a first preset value M1 continuously for a first preset time t1 (S20); and controlling an outdoor unit of the air-conditioning system to stop to prevent slugging from occurring in the compressor when a measured time t of the timer reaches a second preset time t2 (S30). The discharge superheat DSH in the air-conditioning system is monitored in real time, such that a refrigerant drawn back to an air return port of the compressor can be ensured to be in a completely gaseous state, thereby preventing a liquid refrigerant from entering the compressor and preventing slugging. In addition, because a value of the discharge superheat is relatively large, it is convenient to inspect and control data, thereby improving the precision of anti-slugging control, and operation safety and reliability of the air-conditioning system.
