High discharge temperatures in a compressor create which of the following?

High discharge temperatures in a compressor can indeed lead to the formation of black sooty deposits. This occurs because elevated temperatures can cause the thermal decomposition of lubricants or refrigerants, resulting in carbonization. The sooty deposits are a byproduct of this degradation process, which can accumulate on various components within the compressor, potentially leading to performance issues and further heat generation.

Understanding this phenomenon is important for maintaining compressor efficiency and longevity. While it may seem like lower temperatures would foster better lubrication or enhance cooling, high discharge temperatures are detrimental and contribute to efficiency losses. Recognizing the implications of these temperatures can aid in addressing maintenance needs and potential operational adjustments to enhance performance and prevent damage.
