| Your car's engine
is the power source for both heating and air conditioning systems. The
systems also share other components, as the following diagram shows. Here's
what happens when you flip on the heat or the air conditioner: |
| |
 |
Heating
System
Heat is a byproduct
of the engine's combustion 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 blower motor and fan, and temperature and duct
controls, which selct the desired temperature and direct the flow of warm
air. |

Air
Conditioning System
This system shares
air ducts, controls and a blower with the heater, but has its own refrigerant
system. The air conditioning system is comprised of the following components: |
|
| |
|
 |
Compressor
This is a pump
that pressurizes and circulates the refrigerant through the system. |
| |
|
|
| |
 |
Condensor
As the refrigerant
flows through the condensor, it gives up heat and converts from gas to
liquid. |
| |
|
|
| |
 |
Receiver/Dryer
or Accumulator
This is where clean,
dry refrigerant is stored as it circulates through the system. |
| |
|
|
| |
 |
Orifice
Tube or Expansion Valve
This is a metering
device that controls the flow of refrigerant through the system. |
| |
|
|
| |
 |
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 you care |
