Fans and heating systems in cars are critical components for the comfort of the driver and passengers, especially in extreme weather conditions.

Car fans:

Car fans' primary function is to circulate air within the passenger compartment. They are used to improve air quality, remove humidity, and regulate temperature. The ventilation system can be set to different speeds to meet the specific needs of passengers, with the option of directing the airflow toward the windshield, side windows, or the center console.

There are different types of ventilation:

• Simple ventilation : Outside air is allowed into the vehicle, without heating or cooling.
• Recirculation ventilation : The air inside the passenger compartment is circulated without outside air entering. Useful in case of polluted outside air or extreme temperatures.

Car heating:

A car's heating system relies on a heater that uses the heat produced by the vehicle's engine. When the engine is running, the water circulating in the engine's cooling system heats up and releases part of its heat to a radiator that heats the passenger compartment. The warm air is then released into the passenger compartment through vents.

Some modern cars also have gas or electric heating systems that allow the passenger compartment to be heated without the engine running. These are particularly useful in extremely cold conditions.

Additional Features:

• Air Conditioning : Many modern vehicles are equipped with air conditioning systems, which combine heating and cooling functions to maintain a constant, comfortable temperature in all seasons.
• Heated seats : Some models also offer heated seats for added comfort in the winter.
• Defrosting Systems : Fans and heaters are also used to defrost windows, preventing ice or moisture from forming that could impair visibility.

These systems can be adjusted manually via controls or automatically, depending on the options present in the vehicle.
