1. Location of ventilator and vent

In the overall ventilation, the air supply outlet should be set as far away from the ventilator as possible, and in the local ventilation, due to the small space of the ventilation object, it should be as close to the ventilation as possible to reduce the impact on other aspects.

2. Bathroom or toilet

Therefore, ventilation fans often remove indoor moisture, which can maintain the comfort and health of rooms and people.

4) adjust the room temperature

On summer nights, the indoor heat is driven away by the ventilator, so that the cool air outside can be exchanged. The circulating ventilator can keep the indoor temperature uniform and improve the heating effect in winter.
