The main accessories of the fresh air system include air inlet, filtration system, heat recovery device, air supply and exhaust vents. Its working principle is as follows:
Air inlet: The fresh air system inhales fresh air from the outside through the air inlet installed outdoors. These air inlets are usually located on the outer wall of the house to ensure that the air inhaled is fresh.
Filter system: The inhaled air first passes through the filtration system to filter out harmful substances such as dust, pollen, bacteria, etc., to ensure the cleanliness of the air introduced into the room.
Heat recovery device: Some fresh air systems are equipped with a heat recovery device, which can recover the heat in the exhausted dirty air, reduce energy loss, and improve the energy efficiency of the system.
Air supply vent: Fresh air after filtration and (or) heat recovery treatment is evenly distributed to each room through the air supply vent.
Exhaust vent: The dirty air in the room is discharged to the outside through the exhaust vent installed in the room to ensure the freshness and cleanliness of the indoor air.
