Abstract

The invention discloses a control method for anti-liquid-impact of an air conditioning system, and belongs to the field of air conditioner control. The method comprises the steps that temperature dataare acquired, whether the temperature data meet preset conditions for executing the anti-liquid-impact operation is judged; if the preset condition is met, an electric heating device is controlled tobe started. According to the embodiment of the control method for anti-liquid-impact of the air conditioning system and an air conditioner, whether the anti-liquid-impact operation needs to be carried out or not is determined according to the temperature data obtained in real time, when the anti-liquid-impact operation needs to be carried out, the electric heating device is started, the adjustingprocess is simple, and the liquid-impact of a compressor with fixed frequency can be effectively avoided in time. The invention further discloses the air conditioner.

Description

technical field

[0001] The invention relates to the technical field of air conditioning control, in particular to a control method for preventing liquid shock of an air conditioning system and an air conditioner. Background technique

[0002] The compressor is the core component of the entire air-conditioning system, and it is the key to controlling the air-conditioning system to ensure the reliable operation of the compressor under various operating conditions. However, under certain harsh environmental conditions, the amount of refrigerant output by the compressor does not match the heat transfer of the evaporator unreasonably, and the evaporator is prone to insufficient evaporation, and a large amount of liquid refrigerant is directly sucked into the bottom of the compressor by the compressor. Although the surface of the refrigerating machine oil inside the compressor seems to be sufficient, in fact the refrigerating machine oil has been diluted or replaced by the refrige...
