The refrigerant gas then passes through the receiver/dryer so that the contaminants and moisture get removed. It then enters the expansion valve/accumulator. Here, the refrigerant is cooled down further so that it loses the pressure and temperature before it enters the evaporator.
The evaporator can be considered to be a mini radiator that gets colder as it lowers the refrigerants temperature more and, additionally, discards moisture from the air. There is a ventilation system’s blower motor in the system that blows air over the cooled down evaporator and sends cool air into the passenger compartment.
