mineral oil
The compressor oil
Oil in a AC compressor is there so that the mechanical parts don't over heat from friction
To prevent wear on the compressor.

An oil separator in a refrigeration system is designed to remove oil from the refrigerant flow before it returns to the compressor. This helps maintain the efficiency and performance of the system by ensuring that the compressor operates with the appropriate amount of oil for lubrication, preventing potential damage. By separating the oil, the system can reduce the risk of oil accumulation in the evaporator and other components, promoting better heat exchange and overall system reliability.
Floc in refrigeration oil is wax that has separated out from oil containing parathene.
Sludge in a refrigeration system can lead to reduced system efficiency, decreased cooling capacity, and potential damage to components such as the compressor. It can also cause blockages in the system, leading to uneven cooling or system breakdown. Regular maintenance and proper filtration can help prevent the formation of sludge in a refrigeration system.
