What is the main purpose of monitoring discharge temperature in a compressor?

Monitoring the discharge temperature in a compressor is crucial for preventing overheating. When the discharge temperature exceeds a certain threshold, it indicates that the compressor is operating under conditions that could lead to significant damage or failure. High temperatures can result from excessive refrigerant load, insufficient cooling, or mechanical issues within the compressor.

By keeping an eye on the discharge temperature, operators can take corrective actions, such as adjusting the refrigerant flow or checking lubrication levels, before severe damage occurs. This is essential not only for the longevity of the compressor but also for maintaining safe operating conditions within the refrigeration system.

While maintaining sufficient lubrication, ensuring efficiency, and adjusting refrigerant flow are important aspects of refrigeration system operation, they become secondary when considering the critical need to prevent overheating, which can have immediate and severe consequences for compressor operation.
