Electric fans save energy.
The air conditioner is also driven by the car's engine, which is more powerful, while the fan is smaller and powered by the battery.
The car engine generates a lot of heat during the combustion process. Thanks to the water cooling system, the coolant draws heat away from the engine and dissipates it in winter, when you need to turn on the heater. . It will bring heat from the water cooling system inside the cabin, so that hot air appears. It doesn't use any electricity at all, as the heat comes from the heat of the motor running. , this means that it consumes it to blow the air. Electricity does not consume electricity compared to cold air.
