Under abnormal conditions, what is the discharge temperature of the compressor?

In industrial refrigeration systems, the discharge temperature of the compressor is a critical parameter that helps indicate the compressor's operational health and efficiency. Under normal operating conditions, the discharge temperature typically falls within a specific range, but abnormal conditions, such as overloading or insufficient refrigerant flow, can elevate this temperature significantly.

The correct choice indicates a discharge temperature of 234°F, which is characteristic of a compressor that is experiencing stress due to high compression ratios or low evaporator temperatures. A temperature this high points toward issues such as inadequate cooling or heat rejection from the condenser, which can lead to compressor failure if prolonged. It's essential to monitor these temperatures closely to prevent damage, as excessively high discharge temperatures can lead to overheating and a breakdown of the compressor oil.

In contrast, the other temperatures listed would generally fall into more normal operational ranges for industrial compressors, making them inappropriate for situations categorized as "abnormal." Consistently high readings, such as the one indicated by this correct answer, constitute a warning sign for operational challenges that require immediate attention.
