What can happen if liquid refrigerant reaches the compressor?

When liquid refrigerant reaches the compressor, it can lead to significant issues that compromise the operation of the refrigeration system. Compressors are designed to compress gas, not liquid. If liquid refrigerant enters the compressor, it can cause hydraulic lock, leading to mechanical damage such as broken rods or severe wear on internal components.

This situation severely impacts the efficiency of the system because the compressor is unable to process the liquid as it would gas, which is necessary for proper compression and circulation in the system. Additionally, compressor operation under these conditions can lead to overheating and increased wear and tear, ultimately resulting in a shorter lifespan for the compressor itself and possible failure of the refrigeration system.

Recognizing these outcomes is critical for maintaining system reliability and performance, as the correct operation depends on ensuring that only vapor refrigerant enters the compressor, preventing any possible damage or inefficiency associated with liquid entering the system.
