(1) Heating System
Heat is a byproduct of the engine's combusion process. The heat is absorbed by the coolant
in your car's radiator. The coolant is then circulated through the heater core before returning to the radiator.
The heating system also includes a series of air ducts, a blowermotor and fan, and temperature and duct controls, which selct
the desired temperature and direct the flow of warm air.
(2) Compressor
This is a pump that pressurizes and circulates the refrigerant through the system.
(3) Condensor
As the refrigerant flows through the condensor, it gives up heat and converts from gas to liquid.
(4) Receiver/Dryer or Accumulator
This is where clean, dry refrigerant is stored as it circulates through the system
(5) Orifice Tube or Expansion Valve
This is a metering device that controls the flow of refrigerant through the system.
(6) Evaporator Core
Refrigerant enters the evaporator core as a liquid. Heat from the air converts the liquid
refrigerant back into a gas, which cools the air before it enters your car.
