Heating / Air Conditioning
Heating / Air Conditioning
Both the heating and air conditioning systems in your car rely on the engine as their power source and share various components, as illustrated in the diagram below. Let’s delve into the processes that occur when you activate either the heating or air conditioning functions.
- Heating System
Heat is generated as a byproduct of the engine’s combustion process. This heat is absorbed by the coolant in your car’s radiator. The coolant subsequently circulates through the heater core before being directed back to the radiator. The heating system comprises a network of air ducts, a blower motor and fan, as well as temperature and duct controls that enable you to select the desired temperature and direct the flow of warm air.
Air Conditioning System
While sharing air ducts, controls, and a blower with the heater, the air conditioning system operates independently, utilizing its own refrigerant system. The components of the air conditioning system include:
Compressor
This component is a pump responsible for pressurizing and circulating the refrigerant throughout the system.
Condensor
While passing through the condenser, the refrigerant releases heat and undergoes a phase change from gas to liquid.
Receiver/Dryer or Accumulator
This component serves as a storage point for clean, dry refrigerant as it continues to circulate through the system.
Orifice Tube or Expansion Valve
This is a metering device responsible for regulating the flow of refrigerant throughout the system.
Evaporator Core
Refrigerant enters the evaporator core in a liquid state. As air passes over it, the heat from the air transforms the liquid refrigerant back into a gas, subsequently cooling the air before it flows into your car.
