The integrated fresh air system supports internal and external circulation for cleaner, more comfortable airflow. It helps to purify the indoor air with two modes: Internal circulation and external purification. In internal circulation mode, condensed water is electrolyzed to generate oxidizing ozone and oxygen atoms, effectively eliminating bacteria, viruses, and odors. Purified air is then partly released indoors and partly mixed with conditioned air to prevent direct drafts. In external purification mode, outdoor air is filtered and introduced through multiple channels, ensuring a healthy, balanced indoor environment.
