The indoor and outdoor circulation functions of the Wall Mounted Air Fresh Ventilation Device play a crucial role in optimizing air circulation. Here's a detailed explanation of how these functions effectively optimize indoor airflow:

I. Outdoor Circulation Function

The outdoor circulation function of the Wall Mounted Air Fresh Ventilation Device actively draws fresh air from outdoors into the indoor environment. This is particularly important for indoor spaces that remain closed for extended periods, ensuring timely improvement of indoor air quality.

When outdoor air quality is good, activating the outdoor circulation function can effectively increase indoor oxygen content and reduce the concentration of harmful gases like carbon dioxide.

The incoming outdoor air passes through the device's filtration system, effectively removing harmful substances such as dust, pollen, and bacteria, ensuring that only clean air enters the indoor environment.

The high-efficiency filtration system significantly improves indoor air cleanliness, reducing the risk of allergies and respiratory illnesses.

The outdoor circulation function also helps ventilate the indoor environment, expelling stale air and odors, creating a fresh and pleasant indoor atmosphere.

II. Indoor Circulation Function

During cold winters or hot summers, activating the indoor circulation function can effectively maintain indoor temperature, minimizing the impact of outdoor temperature fluctuations on the indoor environment.

The indoor circulation function circulates indoor air, further purifying it through the filtration system, and further improving indoor air quality.

This function is particularly useful when outdoor air quality is poor or when indoor air needs to be quickly purified.

Compared to the outdoor circulation function, the indoor circulation function consumes less energy and generates less noise during operation, providing a more comfortable environment for occupants.

The indoor and outdoor circulation functions of the Wall Mounted Air Fresh Ventilation Device work together through different mechanisms to ensure continuous optimization of indoor air quality. During actual use, users can flexibly switch between indoor and outdoor circulation modes based on the indoor environment and personal needs to achieve the best airflow effect.
