How does the air heater in a car work?
Air-cooled cars. If necessary, the air may be warmed further by an electrically ignited petrol-burning heat exchanger. The heat exchanger also allows the heater to work with the engine off -unlike a water-heated type. The rest of the system, the way in which the heat is distributed, is like that of any other car.
Why does my car blow cold air when the car is moving?
My car has 165 miles. My car has an automatic transmission. When the car is moving, versus stopped, there is more air flow over the condenser (the heat exchanger in front of the radiator) and that airflow is essential to system operation.
Where does the air flow in a car?
Air flow Air enters a large duct at the front of the car, placed so that when the car is moving the entry point is in a high-pressure area and air is forced in. From there it goes to the heater, which warms it if required. Another common entry point is through grilles on top of the bonnet.
How does the cooling system work in a car?
Remember that airflow created by vehicle movement is a bonus, and usually matches the extra heat generated by the engine in moving the vehicle along. The fan must draw enough air to transfer all of the heat in the system. Engine fans have big fan offsets and draw large volumes.
How does a car heating and ventilation system work?
The heater. Incoming air goes through the water-heated matrix and is warmed. There is also an electric fan, which can be switched on to blow air through the system when the car is stationary, or when extra ventilation is called for. The fan can be adjusted to run at different speeds, according to need.
