Which outcome occurs when heat infiltrates an HVAC evaporator?

A)Reduced refrigerant subcooling efficiency
B)Lower compressor discharge pressure
C)Increased oil return to compressor
D)Enhanced dehumidification performance

💡 Explanation

Reduced refrigerant subcooling results because increased heat load invokes the phase change, reducing the liquid portion; therefore, performance declines, rather than compressor protection which needs adequate subcooling to stay cool.
