Is it true or false that high discharge temperatures are good for a compressor, creating a black sooty deposit?

High discharge temperatures are not good for a compressor. They can indeed lead to detrimental effects, such as the formation of carbon deposits, often referred to as black sooty deposits. Elevated temperatures can degrade lubricants, impair the compressor's efficiency, and cause increased wear on internal components. High temperatures indicate that the refrigerant is not effectively being compressed and could also point to other underlying issues, such as insufficient cooling or excess refrigerant flow.

While certain compressors might have varying tolerances for temperature fluctuations, generally speaking, consistent high temperatures pose a significant risk to compressor longevity and operational efficiency. Proper maintenance and monitoring of discharge temperatures are crucial to avoid these negative outcomes.
