How is the condenser outlet pressure measured in an abnormal condition?

The measurement of condenser outlet pressure under abnormal conditions is typically represented in PSIG, or pounds per square inch gauge. This measurement is crucial because it indicates the pressure relative to the ambient atmospheric pressure. By using PSIG, operators can easily assess fluctuations in pressure that may occur due to system anomalies, as this gauge pressure excludes atmospheric pressure from the reading.

Using PSIG is advantageous in refrigeration systems because it allows for monitoring any deviations that may signify issues within the condenser itself, such as blockages or refrigerant flow problems. This helps operators to promptly identify and rectify potential problems, ensuring safe and efficient operation of the refrigeration system.

In contrast, measurements in kPa, PSI, or bar do not inherently provide the same level of insight into gauge pressure as PSIG does, since they may refer to absolute measurements or lack the contextual relationship with atmospheric pressure that is vital for accurate diagnostics in an industrial setting.
