What is the normal reading for compressor discharge temperature?

The normal reading for compressor discharge temperature varies based on the specific type of refrigeration system and the refrigerant used; however, in many industrial refrigeration systems, a discharge temperature in the range of approximately 34°F is often considered an ideal condition, specifically in systems using ammonia as a refrigerant. This temperature indicates that the compressor is performing well, and the refrigerant is being effectively compressed without excessive heat build-up, which can lead to efficiency loss or mechanical failure.

Monitoring the discharge temperature is crucial because it helps ensure the compressor is working within its designed temperature and pressure limits. If the temperature were too low, it could indicate issues such as insufficient refrigerant or improper system operation. On the other hand, significantly higher temperatures could signal overheating, which might damage the compressor or reduce its lifespan.

Other provided options, such as 30°F, do not represent typical discharge temperatures for a properly functioning industrial compressor. Meanwhile, 235°F is unusually high, likely indicating a malfunction, while 8.4 AMPS pertains to electrical current and not directly to temperature measurements, thus highlighting the importance of understanding the specific parameters related to each aspect of refrigeration system operation.
