What is the compressor inlet temperature under normal conditions?

The compressor inlet temperature under normal conditions is typically around 30°F. This is important in refrigeration systems because the compressor functions efficiently when it draws in refrigerant vapor at a low temperature. At this temperature, the refrigerant is in a gaseous state, which allows the compressor to effectively increase both the temperature and pressure of the refrigerant before it is sent to the condenser.

Inlet temperatures that are too high can lead to reduced efficiency and potential damage to the compressor, as the refrigerant is not in the ideal state for compression. The selected option of 30°F aligns with standard practices for industrial refrigeration, where the goal is to maintain optimal thermal conditions for efficient operation.

Higher temperatures, such as 235°F or 254°F, exceed typical operational limits for compressor inlets in refrigeration applications, and the option mentioned with PSIG relates to pressure rather than temperature, making it irrelevant in this context. Understanding the correct inlet temperature is crucial for maintaining system performance and ensuring reliability in refrigeration systems.
