Heating & A/C (A7)Câu 82 / 120
The component that changes high-pressure refrigerant vapor into a liquid by removing heat is the:
a.Condenser
b.Evaporator
c.Accumulator
d.Expansion valve
Giải thích
The condenser, mounted in front of the radiator, rejects heat so the high-pressure vapor condenses into a liquid. Airflow across it is essential; a blocked or dirty condenser causes high pressures and poor cooling. The evaporator, by contrast, absorbs heat inside the vehicle.
