What does liquid slugging refer to in the context of refrigeration?

• A. Liquid refrigerant in the system pipes
• B. Liquid refrigerant in the compressor clearance space
• C. Liquid refrigerant in the condenser
• D. Liquid refrigerant entering the evaporator

Answer: (B)

Liquid slugging specifically refers to a condition that occurs when liquid refrigerant enters the compressor clearance space. This can lead to significant mechanical damage because compressors are designed to compress vapor rather than liquid. When a compressor tries to compress a liquid, it can result in fluid hammer, causing stress on the compressor components and potentially leading to failure. In refrigeration systems, it is critical to ensure that only vapor reaches the compressor, as the presence of liquid in this part can interrupt the normal operation of the compressor, reduce its efficiency, and even damage the unit itself. Therefore, understanding that liquid slugging involves liquid refrigerant in the compressor clearance space is key for maintaining the proper functioning and longevity of refrigeration systems.
