What consequence might occur if the discharge pressure exceeds the expected value?

When discharge pressure exceeds the expected value in a refrigeration system, one notable consequence is the potential reduction in the lifespan of the compressor. Compressors are designed to operate within a specific pressure range, and exceeding this range can lead to various mechanical and thermal stresses.

High discharge pressure can cause the compressor to work harder than it should. This excessive workload often results in overheating, which can damage the internal components of the compressor, such as bearings and seals. Over time, this can lead to premature compressor failures.

Moreover, the increased pressure can cause the refrigerant to operate inefficiently, leading to further strain on the compressor as it attempts to maintain the desired cooling effect. If these conditions persist without intervention, the overall reliability of the refrigeration system diminishes, leading to increased maintenance costs and potential downtime.

Thus, acknowledging the impact of high discharge pressures on compressor integrity is crucial for maintaining the longevity and efficiency of an industrial refrigeration system.
