Heating & A/C (A7)Câu 81 / 120
In an automotive A/C system, the compressor's job is to:
a.Condense refrigerant into a liquid
b.Store refrigerant
c.Raise refrigerant pressure and circulate it through the system
d.Absorb moisture from the refrigerant
Giải thích
The compressor pressurizes low-pressure refrigerant vapor and pumps it through the system, raising its temperature and pressure before the condenser. It is the pump that drives the refrigeration cycle. A failed compressor clutch or internal damage stops cooling.
