← TechnologyWhich outcome occurs when excess humidity accumulates near air conditioner's evaporator?
A)Ice formation reduces heat exchange✓
B)Refrigerant flashes increasing thermal efficiency
C)Compressor workload decreases indefinitely over time
D)Evaporator pressure unexpectedly shows rapid increase
💡 Explanation
Ice formation occurs because excessive humidity leads to water condensation, and the system operating below freezing causes the water to freeze. This frosting acts as thermal insulation, using the mechanism of thermal blockage and reduces heat exchange to refrigerant, therefore cooling output decreases, rather than improving due to flash or pressure rising.
