What could indicate a problem in the condenser's operation when measuring outlet drain temperature?

High temperature readings from the outlet drain of the condenser indicate a potential problem in the condenser's operation. In a properly functioning condenser, the outlet drain temperature should remain within a normal operational range that is indicative of effective heat exchange and efficient refrigerant cooling.

When the temperature readings are higher than expected, this could suggest several issues, such as inadequate cooling, a restriction in the refrigerant flow, or an overburdened system due to high ambient temperatures or excessive load. Such elevated temperatures may lead to decreased efficiency and could potentially affect the overall refrigeration system negatively, risking overheating and compromising the reliability of the process.

The other options, though relevant, do not signify malfunction as directly. Normal operational range suggests that the system is working correctly. Low pressure readings might imply other issues but not directly correlate to condenser outlet temperature problems without further context. Consistent readings with no fluctuation can indicate stable operation, which is not symptomatic of a problem. Therefore, high temperature readings serve as a clear signal to investigate further and troubleshoot the condenser's function.
