What is liquid slugging?

High oil levels in the compressor
Liquid refrigerant in the compressor clearance space
Low refrigerant levels in the system
Refilling the refrigerant in the system

The correct answer is: High oil levels in the compressor

Liquid slugging occurs when liquid refrigerant enters the compressor and is not properly vaporized before entering the compression chamber. This can lead to damage to the compressor components due to the inability to compress a liquid. High oil levels in the compressor could contribute to liquid slugging by mixing with the refrigerant and creating a liquid refrigerant-oil mixture that can enter the compressor. Therefore, high oil levels in the compressor are associated with the occurrence of liquid slugging. The other options do not directly describe the phenomenon of liquid slugging in air conditioning systems.
