← ScienceWhich outcome occurs when a refrigeration system uses HFC refrigerants?
A)Reduced system energy efficiency✓
B)Lower operational pressures achieved
C)Accelerated compressor mechanical wear
D)Increased ice formation during cooling
💡 Explanation
Reduced system energy efficiency occurs via increased heat transfer from the refrigerant because global warming potential requirements impact a refrigerant's latent heat of vaporization, influencing condenser behavior. Therefore the system's coefficient of performance decreases, rather than alternatives affecting pressure or causing icing.
