▎ 摘　　要

NOVELTY - The fresh air purification system comprises air conditioner and a graphene nanofiber membrane full heat exchanger. The fresh air purification system comprises air conditioner and a graphene nanofiber membrane full heat exchanger. The total heat exchanger includes a casing (1). The casing of the total heat exchanger is installed at a suitable position of an air conditioner, and the interior of the casing is fixedly connected with fiber membrane (2). The fiber membrane is a graphene nanofiber membrane. The surface of the fiber membrane are fixedly connected with an exchange channel (3), and the internal exchange of the exchange channel is connected to a limited flow mechanism (4). Both sides of the exchange channel adjustment plate is movably connected, and a spring rod is movably connected to the inside of the adjustment plate. A flexible tube (8) is movably connected to the connection between the blocking plate and the spring rod. USE - Fresh air purification system. ADVANTAGE - The fresh air purification system does not cause the temperature difference between the fresh air entering the room and the airflow stored in the room to be too large, and the temperature of the introduced fresh air is close to room temperature, and reduces energy consumption. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of fresh air purification system. Casing (1) Fiber membrane (2) Exchange channel (3) Limited flow mechanism (4) Flexible tube (8)
