What is a sign of a well-functioning ammonia refrigeration system?

A sign of a well-functioning ammonia refrigeration system is indicated by stable pressure readings. When pressure remains steady during operation, it reflects that the system is effectively maintaining a consistent refrigerant flow and is operating within its designed pressure parameters. This stability suggests that components such as compressors, evaporators, and condensers are functioning properly without significant leaks, blockages, or other issues that could disrupt the system's efficiency.

In contrast, fluctuations in pressure readings may signal underlying problems such as refrigerant leaks, changes in load conditions, or mechanical issues with the compressor. Proper pressures are essential for optimal system performance, ensuring that the refrigeration cycle can efficiently absorb and reject heat as intended. Hence, stable pressure readings are a crucial indicator of overall system health.
