Which of the following temperatures indicates an abnormal condition for the discharge?

The identification of discharge temperature as an indicator of abnormal operating conditions is crucial in maintaining the efficiency and safety of refrigeration systems. A discharge temperature of 192°F is significantly elevated compared to typical discharge temperatures which generally range from 130°F to 160°F for many industrial refrigeration systems. When the discharge temperature exceeds this range, it may suggest issues such as inadequate cooling, overloading of the compressor, or high ambient temperatures causing the system to work harder than normal. Elevated temperatures can lead to increased wear and tear on system components, potential compressor failures, and degradation of the refrigerant.

In contrast, temperatures such as 154°F and 95°F would typically be within or around operational limits, indicating the system is functioning properly. A pressure of 181 PSIG, while potentially outside normal operational thresholds in some contexts, does not specifically reflect a temperature concern. Thus, a discharge temperature of 192°F clearly stands out as indicative of an abnormal condition requiring immediate attention.
