The ventilation of central fresh air system is not only to exhaust the polluted air, but also has the functions of deodorization, dust removal, moisture removal and room temperature regulation in addition to the ventilation function. The transmission mode of central fresh air adopts displacement type, rather than the internal circulation principle of air conditioning gas and the unhealthy practice of mixing old and new gas. In 1935, Auston Chun invented and manufactured the world's first heat exchange equipment that can filter air pollution, also known as fresh air system.

Outdoor fresh air will be automatically sucked into the room through negative pressure. When it enters the room through the new air outlet installed on the bedroom, living room or living room window, it will automatically remove dust and filter. At the same time, the corresponding indoor pipeline is connected with the exhaust outlets in several functional rooms, and the formed circulation system will take away the indoor exhaust gas and concentrate on the exhaust outlet to "exhale", while the exhaust gas will no longer be recycled, and the old and new wind forms a good circulation. Moreover, considering the energy conservation and reuse, the discharged air will be heat recovered, and the recovery rate will reach more than 80% as a new energy.
