← TechnologyWhich risk increases significantly when laminar flow fails inside an evaporator?
A)Coolant circuit thermal runaway
B)Compressor oil viscosity reduction
C)Localized surface ice buildup✓
D)Decreased refrigerant subcooling period
💡 Explanation
Localized ice buildup risk escalates greatly because reduced airflow creates a thermal bottleneck that accelerates water vapor freezing via ice nucleation, therefore leading to equipment damage, rather than efficient convective cooling as expected.
