The fresh air system consists of an open circulation system with fans, air inlets, exhaust outlets and pipes. After starting the fan, negative pressure is formed indoors, and the polluted air is discharged to the outside through the exhaust outlet. At the same time, fresh air from outdoors enters the room through the air inlet. The outdoor fresh air and the indoor dirty air exchange energy through a high-performance air mass exchanger (heat converter). Part of the energy of the dirty air is transferred to the fresh air. The fresh air is preheated (precooled) and humidity exchanged before being sent into the room. The fresh air system can comprehensively and thoroughly discharge harmful chemical odors, pollutants, moisture, odor, viruses, bacteria, etc. in the room to the outside to keep the indoor air fresh.
