What is the potential consequence of introducing excessive liquid refrigerant into the compressor?

Introducing excessive liquid refrigerant into the compressor can lead to compressor lock-up, which is a serious issue in refrigeration systems. The compressor is designed to handle vaporized refrigerant, which allows it to compress and circulate through the system effectively. When liquid refrigerant enters the compressor, it can create hydraulic lock, where the liquid does not compress and causes mechanical damage to the compressor components. This situation can lead to increased wear and potentially catastrophic failure of the compressor due to the inability to properly function under these conditions.

In contrast, increased cooling capacity, improved efficiency, and reduced power consumption are typically the outcomes associated with an optimal balance of refrigerant, not excessive amounts leading to such complications. Hence, the potential consequence of introducing excessive liquid refrigerant into the compressor is indeed compressor lock-up, as this scenario directly disrupts the intended operation and can lead to severe system failures.
