Which condition can lead to compressor failure due to high temperatures?

High discharge temperature is a critical factor that can lead to compressor failure, as it indicates that the compressor is operating under excessive thermal stress. When the discharge temperature rises above the designed safety limits, it may cause several problems.

First, elevated temperatures can lead to overheating of the compressor components, including the motor windings, which can result in insulation breakdown and electrical failures. Additionally, high temperatures can affect the lubrication within the compressor; oil may start to degrade or thin out, compromising its ability to properly lubricate moving parts. This can lead to increased wear and tear on these components, culminating in a total failure of the compressor.

Moreover, high discharge temperatures can also indicate inefficient refrigeration cycles due to a variety of issues, such as insufficient refrigerant flow or excessive load on the system. In worst-case scenarios, prolonged exposure to high discharge temperatures can severely damage the compressor, ultimately leading to its failure.

Addressing the causes of high discharge temperatures is essential for maintaining compressor health and ensuring efficient operation in refrigeration systems.
