Carbon emission fan time

Between 9 am and 6 pm.

Because the noise of the fan in the underground garage is relatively loud, it is usually between 9 am and 6 pm every day in order not to affect the daily rest of the owner. The reason why the fan is turned on in the community garage is mainly because the weather is hot in summer and the underground garage is humid, so it is necessary to turn on the fan for ventilation.
