When these air conditioners are running, the room is often tight for the reason of energy saving. And that reduces the natural ventilation to remove the stale air and replace it with a fresh supply. So, in many situations, we can feel the effect of poor indoor air quality (IAQ) because of the accumulated pollutants and the insufficient fresh air. The poor indoor air quality affects not only the emotion but also the occupant’s health. In order to promote the air exchange rate and consider less influence to nowadays air conditioners, a ventilation fan and the methods to improve the indoor air quality is suggested here. We, therefore, design an air-conditional ventilation fan system that does not affect the habit of those using traditional air-conditioning. The system adopts simpler fans exhausting less energy to lead into outdoor air in the nick of time. So those fans can promote the indoor ventilation to achieve our healthy require and are not burdens to traditional air-conditioning. The amount of indoor ventilation can been adjusted by the “User Mode” or the “Auto Mode”. According to the condition of outdoor air, the outdoor is drew in to adjust indoor air. In addition, the energy is saved by leading into the serviceable outdoor cool air. Consequently, the ventilation fan system can both satisfy the demands of the thermal comfort and meet the function of saving energy.
