← ScienceWhich outcome occurs when a refrigeration cycle's subcooling decreases significantly?
A)Reduced cooling capacity and efficiency✓
B)Increased compressor discharge temperature
C)Frozen evaporator coil operation
D)Higher condenser pressure swings
💡 Explanation
When subcooling decreases, the refrigerant entering the evaporator contains less liquid and more flash gas because of reduced heat rejection in the condenser, leading to lower latent heat absorption and reduced cooling capacity and coefficient of performance. Therefore reduced cooling capacity and efficiency results,rather than higher discharge temperature, freezing coils, and wild pressure swings, which originate with very diffent flaws.
