← ScienceIn a refrigeration system using R-134a, which consequence results from compressor overheating and Freon molecular decomposition?
A)Formation of corrosive hydrofluoric acid✓
B)Iced evaporator coil constriction
C)Increased lubricant oil viscosity
D)Condenser pressure relief activation
💡 Explanation
Decomposition of R-134a releases fluorine which reacts with trace moisture via nucleophilic substitution. This bond breakage forms hydrofluoric acid (HF), because HF formation reduces system PH; therefore, corrosion risk increases rather than viscosity or pressure relief.
