Does a car consume fuel when using only the fan without the air conditioner?

[LeCaroline]

Using only the fan without the compressor in a car does consume fuel. Reasons for fuel consumption: Even when the compressor is off and only the fan is running, fuel is still consumed. This is because, according to the working principle analysis, it does consume fuel. The fan is one of the components that consume electricity. When the fan is turned on, the engine speed increases. You can observe that the engine RPM rises momentarily when the fan is activated. Working principle of the electric fan: The main component of an electric fan is the AC motor. Its working principle involves the rotation caused by the force exerted on the electric coil in a magnetic field. The energy conversion process is as follows: electrical energy is primarily converted into mechanical energy, but since the coil has resistance, a portion of the electrical energy is inevitably converted into heat energy.
