Which situation could potentially result in damage to a reciprocating compressor?

A reciprocating compressor relies on both the proper intake and discharge of refrigeration gases to function safely and efficiently. When the discharge service valve is closed while the compressor is running, pressure builds up in the discharge line, which can lead to excessive pressure levels within the compressor itself. This situation can result in mechanical failures or even complete breakdowns due to the inability of the compressor to relieve pressure effectively.

In addition to the potential for increased wear or catastrophic failure, closed discharge valves can also lead to overheating. This is because the compressor continues to operate, but with no pathway for the refrigerant to exit, the heat generated during compression has nowhere to go. Over time, this can damage internal components, including valves, gaskets, and bearings. Understanding the importance of maintaining open discharge paths during operation is key to ensuring the longevity and reliability of a reciprocating compressor.
