← TechnologyWhich outcome occurs when a refrigeration system uses an incompatible refrigerant with mineral oil lubricant?
A)Compressor valve damage from oil dilution
B)Evaporator icing from moisture absorption
C)Condenser corrosion from acid formation
D)Expansion valve clogging from wax deposition✓
💡 Explanation
When an incompatible refrigerant is used with mineral oil, poor miscibility causes oil to separate and paraffin wax precipitates at low temperatures, blocking the expansion valve. Therefore expansion valve clogging results, rather than valve damage, icing, or corrosion, each requiring distinct chemical processes.
