In a refrigeration system, what does the failure of the equalizer line generally indicate?

In a refrigeration system, the equalizer line plays a critical role in maintaining proper pressure balance between the high and low sides of the system. When the equalizer line fails or malfunctions, it often indicates that the liquid levels in the system are mismatched. This mismatch can lead to one side of the system not receiving the appropriate amount of refrigerant, disrupting the flow and causing inefficient operation.

Maintaining balanced refrigerant levels via the equalizer line ensures that the expansion device operates correctly, preventing issues such as liquid refrigerant returning to the compressor or excessive pressure build-up. Recognizing the symptoms of a malfunctioning equalizer line can help operators diagnose and address potential problems before they escalate, ensuring the efficiency and longevity of the refrigeration system.
