High Boiling Residue & Solids
Equipment Type: Vapor-Compression
Fluid Type: CFC, HFC, HCFC Refrigerants

In operating equipment, the refrigerant will mix with the compressor oil in the normal operation of the cycle. A refrigerant sample taken from a chiller will normally have some small percentage of oil or "high boiling residue". Excessive amounts of oil and other solids present in the refrigerant can indicate problems with the system.
