← ScienceWhich consequence results when a refrigerant leaks past an expansion valve in a refrigeration system, causing premature phase change?
A)Decreased evaporator section latent heat absorption✓
B)Increased compressor motor winding temperature
C)Superheated vapor entering compressor suction line
D)System overcharges due to refrigerant accumulation
💡 Explanation
Decreased latent heat absorption occurs because flash vaporization at the valve reduces refrigerant available at the evaporator; therefore overall cooling decreases rather than other consequences because of reduced liquid available.
