What does the term "flooding" refer to in refrigeration terminology?

In refrigeration terminology, "flooding" specifically refers to the condition when liquid refrigerant enters the compressor. This can occur when the system is not operating correctly, leading to excessive amounts of liquid refrigerant accumulating in the suction line. Compressors are designed to compress gases, and when liquid refrigerant enters, it can cause significant damage due to hydrodynamic action, which can result in compressor failure.

Understanding flooding is crucial for maintaining the efficiency and integrity of refrigeration systems. It emphasizes the importance of proper refrigerant management, as liquid refrigerant in a compressor can disrupt the normal operation and lead to operational issues or equipment damage. This concept is central to understanding the overall functionality and maintenance of refrigeration systems.
