What is the normal compressor discharge pressure?

The normal compressor discharge pressure is typically expressed in pounds per square inch gauge (PSIG), rather than in temperature degrees Fahrenheit. The value 154 PSIG represents a standard range for discharge pressures in many industrial refrigeration systems, thus making it the correct answer.

Compressor discharge pressure is a critical metric in refrigeration systems because it directly relates to the efficiency and effectiveness of the refrigeration process. It indicates the pressure of the refrigerant as it is compressed and discharged from the compressor into the condenser. In a well-functioning system, this discharge pressure should be sufficient to maintain the necessary flow of refrigerant throughout the system while preventing issues like flooding or starvation of the evaporator.

Understanding the significance of compressor discharge pressure is essential for maintaining operational efficiency, diagnosing issues, and ensuring proper system maintenance.
